Deoxyribonucleic acid (DNA) was extracted from air-dried blood spotted on Fast Technology for Analysis (FTA) card. The extracted DNA were amplified with predefined mitochondria (mtDNA) primers. A total of 843 base pair fragment of the mitochondrial DNA (mtDNA) D-loop region of 30 pigs were analyzed. Seven (7) haplotypes and 64 polymorphic sites were identified, with no insertion or deletion between nucleotide 3 and 835. The mean haplotypic and nucleotide diversity were found to be 0.381±0.058 and 0.315±0.155 respectively. The phylogeny revealed one divergent haplotype clade, suggesting one possible maternal lineage (European domestic pig) in South-west Nigerian pigs. The median joining network formed a star-like pattern, suggesting population expansion from a small number of founding ancestor (IFE1). Genetic variation within and between populations accounted for 63.32% and 36.68% of the total genetic variation respectively. This study concluded that there was relatively high genetic diversity in our indigenous pig population, thus, will probably pave way for preservation and improvement of Nigerian pigs as genetic resources.</p> <p><strong>Keywords</strong>: mtDNA, genetic variation, phylogenetic relationship</p> A.B.

Indigenous species have suffered a sharp decline in population from hunting, diseases and slaughter as food animals by different tribes in Nigeria. Very little information on their cardiac excitability is available, owing to negligence and lack of comprehensive and coherent national program on donkeys’ conservation and preservation, hence the need to carry out the study. The study was carried out using 22 apparently healthy Jacks (male donkeys) with a mean age of 8 ± 0.7 years and an average weight of 135kg ± 0.5. The donkeys were manually restrained on standing position on an insulated ground surface using a rubber mat; Electrocardiogram was conducted using single lead channel ECG recorder (EDAN VE-100). The durations of P, R, T, QRS, P-R interval and Q-T interval were recorded as well as the amplitudes of P, R and T. The highest amplitude of P- wave was obtained in lead II while the highest R-wave amplitude was obtained in lead aVR. P and T wave’s durations were highest in lead aVR while higher R-wave and QRS complex durations were obtained in leads aVL and aVF, respectively. The P-R and Q-T intervals (duration) were highest in lead I. Positive P-wave, Negative T-wave and Negative deflection of QRS complex were predominant. Variable QRS-complexes were recorded with predominant QS deflection. The mean heart rate was 52.8±1.8 and ranged between 30-142beats/minute. ECG parameters of donkeys in Sokoto differ from that of other breeds. Data generated will serve as baseline references for quick detection of deviations and early diagnosis and management of potential cardiovascular conditions in studied breed.</p> <p><strong>Key Words</strong>: Arrhythmias, Electrocardiogram, Tropics, Auraki Donkeys, Extinction, Sokoto</p> B.

One hundred and twenty Arbor acre broiler chickens were used for the experiment. At day-old, the birds were acclimatized for 7 days, after which the birds were randomly allotted into 4 treatment groups which was replicated three times with 10 birds per replicate in a Completely Randomized Design. Four experimental diets were formulated in which the first treatment (T1) served as the control without vitamin, second treatment (T2) had 100mg of vitamin C per kg of feed, third treatment (T3) had 200mg of vitamin E per kg of feed, and fourth treatment (T4) had combination of 100mg vitamins C and 200mg Vitamin E per kg of feed. Data were collected on feed intake, weight gain, feed conversion ratio, environmental temperature, relative humidity, rectal temperature, pulse rate and respiratory rates of the chicken. Data were subjected to descriptive statistics, correlation analysis and Analysis of Variance using SAS (9.13). There were no significant effects on growth performance parameters monitored. Physiological indices showed mean values of 40.08 ± 5.85 0C, 67.41 ± 7.22 beats/min and 60.34 ± 5.84 breathes/min for rectal temperature, pulse rate and respiratory rate of the broiler chicken, respectively. There were low and positive correlations between rectal temperature and pulse rate of the chickens (r = 0.23); rectal temperature and respiratory rate (r = 0.15); pulse rate and respiratory rate (r = 0.32). There were significant (p&lt;0.05) effects of Vitamins C and E on rectal temperature, respiratory rate and pulse rate of the chickens. Based on the findings of this study, it was concluded that Vitamin C supplement was most effective than Vitamin E and their combination in suppressing thermo-physiological responses of the broiler chicken.</p> <p><strong>Keywords</strong>: Humidity, response, temperature, physiology, supplement</p> T.I.

A total of one hundred and eighty (180) cockerels with an average weight of 250±0.50g were randomized into six treatment groups. Each treatment group comprised of ten birds per replicate and was replicated three times. Treatment 1 (T1) (250 mg turmeric/kg of feed + coconut oil), treatment 2 (500 mg turmeric/kg of feed + coconut oil), treatment 3 (250 mg turmeric/kg of feed), treatment 4 (500 mg turmeric/kg of feed), treatment 5 (control), treatment 6 (500 mg turmeric/kg of feed + Vitamin C).Weekly body weight and daily feed intake of the birds were recorded for 7 weeks, after which carcass analysis was carried out. At the end of seven weeks, blood samples from ten birds per treatment were collected for haematology and serum biochemical parameters after which six chickens were humanely sacrificed for carcass analysis. Samples of ingesta were collected from crop and ileum and analyzed for lactobacillus counts. There was significant difference (p&lt;0.05) in the average weight gain of birds with birds in treatment 2 having the highest weight gain. In all carcass parameters, there was no significant difference among the treatments. The packed cell volume (PCV) of birds in T1 group (27.00±0.45%) was significantly highest when compared with birds in other treatments. The serum total protein and albumin of birds in groups T4 (7.860±0.15g/dl) and T6 (7.880±0.36g/dl) were significantly (p&lt;0.05) highest compared to other groups. There was no significant difference in the lactobacillus counts in the crop while birds in T2 group had the highest (2.68±0.21 CFU/ml) lactobacillus counts. It can be concluded that <em>Curcuma longa</em> fed to cockerels have no deleterious effect and can be included in their feed up 500 mg/kg of feed with or without coconut oil.</p> <p><strong>Keywords</strong>: <em>Curcuma longa</em>, cockerel, growth performance, haematological parameters, microbiological indices</p> B.O.

A total of 46 Balami (18 males and 28 females), 30 Uda (5males and 25 females), 36 Yankasa (9 males and 27 females) and 37 WAD (7 males and 30 females) were sampled. Sampling was done from the selected States based on distance from one another and an abundance of sheep. Data were collected during the hottest season of November to March. Blood samples were collected from 60 adult sheep out of the entire population for the study. Blood samples were collected from jugular vein puncture using a 5ml syringe, and the samples were then transferred into well-labelled ethylene diamine tetra acetate (EDTA) bottles. Data collected for the study were analyzed using the General Linear Model Procedure of SAS using the fixed-effect model that incorporated breed, sex and age of the sheep. The pulse rate of adult Balami sheep was higher than what was obtained from the other three breeds (P&lt;0.01). The pulse rate for Balami sheep was 94.33±6.50 beats per minute as against those of WAD, Uda and Yakasa (77.42±8.38, 76.85±8.38 and 72.80±7.84 beats per minute, respectively). Adult WAD, Yankasa and Balami had similar (p&gt;0.05) respiratory rate (73.92±8.73, 71.20±7.73, 69.33±6.40 breath per minute, respectively). The values for the three breeds were higher than 67.76±8.16 breath per minute obtained for Uda sheep. The rectal temperature of adult Balami (39.29±0.21oC) and Yankasa (39.21±0.25oC) were similar but differed from the values obtained for adult WAD sheep (38.40±0.29oC). Malondialdehyde (MDA) is not a good marker for monitoring heat stress among breeds of sheep in Nigeria because breeds did affect (p&gt;0.05) the activity level of MDA. Metabolic markers like thyroid, cortisol hormones level and glucose could also be used in the future. Pulse rate had a high and positive correlation (0.452; P&lt;0.01) with an atmospheric temperature of Balami sheep. Moderate and positive correlations (0.265, 0.221; P&lt;0.05) were obtained between pulse rate and temperature of Uda sheep and WAD, respectively. Molecular markers of biochemical and heat stress such as like heat shock protein (HSP) should be used to study the diversity of sheep breeds in Nigeria.</p> <p><strong>Keywords</strong>: Biochemical, Nigeria, physiological profile, sheep, heat stress.</p> R.O.

Cola rostrata seed was processed using different methods; boiling, boiling/fermenting, fermenting, and toasting to eliminate the anti-nutritional factors in it. Six (6) experimental diets were formulated with diet 1 (Control) containing 0% CRSM, while diets 2, 3, 4, 5 and 6 contained boiled, boiled/ fermented, fermented, toasted and raw CRSM respectively. Sixty (60) weanling male rats aged 6-7 weeks, were randomly divided into the six (6) dietary treatments groups, which were replicated twice with five (5) rats per replicate in a Completely Randomized Design (CRD). The experiment lasted for 21 days. The results indicated that there were significant differences (P&lt;0.05) in packed cell volume (PCV) and Haemoglobin among the treatment groups. The raw seed (diet 6) resulted in the reduction of the serum total protein, serum albumin and serum globulin. It is concluded that Cola rostrata seed boiled for 30 minutes can be used as feed ingredient in replacing maize in animal diets without adverse effects on haematological and serum biochemical indices studied.</p> <p><strong>Keywords</strong>: Cola rostrata seed meal; haematology; serum biochemistry; and male wistar rats</p> Grace.

The result showed that 14 (5.7%) samples were positive for endoparasites. There were prevalence variations among different endoparasites such as Ascaridia galli (2%), Raillietina tetragona (0.4%), Subular brumpti (0.4%) and Eimeria oocyst (2.9%). The endoparasites in local chicken revealed Eimeria oocyst and Ascaridia gallias 5.7% and 14.3% respectively, but layers reported Eimeria oocysts 8.6%. While Broilers recorded 2.9% of Eimeria oocyts, Raillietina tetragona and Subular brumpti each. Pigeon also recorded 2.9% of Eimeria oocyts. In Checheniya market, 1 (2.9%) was positive for <em>Ascaridia galli</em> and in Library market, <em>Eimeria oocyst </em>and<em> Ascaridia galli</em> had 1 (2.9%), while in <em>Kasuwan Barci, Eimeria oocyst </em>and<em> Raillietina tetragona</em> had 1 (2.9%), and Kawo market had 1 (2.9%) with <em>Subbular brumpti</em>., Railway market had 2 (5.7%) , with <em>Eimeria oocyst</em>, and in Sabo market,<em> Eimeria oocyst</em> and <em>Ascaridia galli</em> had 1 (2.9%) while in Station market, Eimeria oocyst and <em>Ascaridia galli</em> had 2 (5.7%). Conclusively, this study observed a less prevalence of endoparasitism of poultry with 5.7% prevalence rate and <em>Eimeria oocyst</em> was implicated as the most infested parasite in live bird markets within Kaduna metropolis.</p> <p><strong>Keywords</strong>: Screening, Endoparasites, Live-birds Markets, Species of birds.</p> F.B.

A total of 384 faecal samples were examined, the overall positive for the parasite was 86.19% of which, 87.31%, in sheep and 85.03% in goats. Sex and species did not significantly influence (p &gt; 0.05) the trend of infection. The prevalence of identified pathogenic species present in sheep were <em>Eimeria crandallis 5(3.22%), E. ovindallis 8(5.16%)</em> and mixed infection 142(82.59.6%). The prevalence of pathogenic species from goats were <em>E. arloingi</em> 27 (30 %), <em>E. ninakohlyakimovae</em> 12(13.33%), E. christenseni 8(8.89%) and mixed 43(47.78%) infections. There was significant (p &lt; 0.05) difference observed in prevalence of <em>coccidia spp</em>. in Mocharae compared with the other study sites. The overall prevalence of pathogenic Eimeria species was 63.8 %, while the prevalence of that in sheep and goats were 78.68% and 48.13% respectively. Species, sex and age of animals in this case significantly influenced (p &lt; 0.05) the prevalence of pathogenic Eimeria species. The females (74.87%) significantly (p &lt; 0.05) had higher infection rates than males (53.3%). Animals of age 3 months (91.13%) had significantly (p &lt; 0.05) higher prevalence rates than 4-6 months (59.86%) and 7-12 months (38.94%).

Their ages ranged between 1.5-2 years, their body condition score was 3 out of 5 scale. Test groups were ascorbic acid at 400mg/kg orally administered; ascorbic acid at 300mg/kg PO; ascorbic acid at 200mg/kg PO and control group without ascorbic acid administration. Thus, 16 animals were used for high stocking rate and 16 stocked using low stocking rate in the experiment. Physiological and biochemical parameters were assessed. The heart rates of the bucks treated with 200mg/kg ascorbic acid midway into the journey were low (P&lt;0.05) compared to those treated with 300 and 400mg/kg, and the control group. High dose of ascorbic acid (400mg/kg) produced significantly higher values of sodium and chloride serum concentrations. Mg levels were significantly (P&lt;0.05) lowered with lower doses of ascorbic acid treatment compared to the control. In contrast, T4 values in all treated groups were lower than that of the control animals. Ascorbic acid caused a significant (P&lt;0.05) increase in red blood cells; the leucocytes and lymphocytes counts. Conclusively, ascorbic acid at 300 mg/kg and 400 mg/kg had better anti-stress property that could be used to improve animal welfare in bucks exposed to long road transportation.</p> <p><strong>Key Words</strong>: Ascorbic acid; Doses; Stress; Sahel bucks.</p> K.T.

Thirty-two apparently healthy Sahel bucks were subjected to an experimental journey. Four groups were randomly assigned into control none treated, xylazine (0.02 mg/kg) and ascorbic acid (200 mg/kg), xylazine (0.01 mg/kg) and ascorbic acid (400 mg/kg), xylazine (0.015 mg/kg) and ascorbic acid (300 mg/kg) each group had four animals each in both high and low stocking density sub-groups. The xylazine was administered intravenous while ascorbic acid was administered orally. Group (0.02mg/kg) xylazine and (200mg/kg) ascorbic acid at high stocking rate significantly (p &lt;0.05) increased the dressing percentage, while low stocking rate decreased using the same combination significantly (p &lt;0.05) decreased dressing percentage. Group of (0.015mg/kg) xylazine and (300mg/kg) ascorbic acid at high stocking rate significantly (p &lt;0.05) increased the excitatory score at slaughter. There were also interactions of treatment on excitatory score, dressing percentages and triiodothyronine. This means that the treatment using the two drugs influenced these parameters.

Black Bovan Nera hen strain (n=480) aged 59 weeks were randomly allotted to five dietary treatments; each treatment was replicated six times with eight hens per replicate. The hens were raised in a conventional cage and an open-sided deep litter (DPL) HS. Five isocaloric and isonitrogenous diets were formulated and each was supplemented with 0.25% proprietary VMP 1, 2, 3, 4 and 5 for the hens in cage and DL in 2x5 factorial arrangement and completely randomized design. At age 71 weeks, six randomly selected eggs per treatment (n=60) were processed and assayed for vitamin B1, folate, B6 and D3. Significantly higher (p&lt;0.05) thiamine deposition (0.063 mg/100g) was in the eggs of hens on VMP5 with similar (p&gt;0.05) content of pyridoxine, folic acid and vitamin D. The HS had significant impact on vitamin D (93.969 IU) and foliate content (51.909 mg/100g) of the eggs in the DPL. Effect of interactions of HS x VMP on pyridoxine, folic acid and vitamin D3 deposition in egg were similar (p&gt;0.05) but was significantly higher (p&lt;0.05) for thiamine deposition. Hens from DPL had higher vitamins deposition in egg than cage, while vitamin depositions in eggs were influenced by different the proprietary VMP and HS.</p> <p><strong>Keywords</strong>: Deep litter, Battery, Proprietary vitamin-mineral premixes, Vitamin composition</p> O.A.

A total of 96 two-weeks old American bronze turkey poults were randomly allocated into four dietary treatments. 24 poults per treatment replicated thrice with 8 turkey poults per replicate in a completely randomized design (CRD). The turkey poults were given a basal diet supplemented with 0, 0.2, 0.4 and 0.6% ginger powder during the 42days of the experiment. Growth performance and serum biochemistry were determined. The final liveweight, body weight gain and feed conversion ratio improved in treatment groups especially among turkey poults fed diet containing 0.6% of ginger powder. The supplementation of ginger powder at 0.6% reduced cholesterol, triglyceride, low density lipoprotein, ALT, AST values and increased the high density lipoprotein value. Supplementing turkey poults with ginger enhanced the growth performance and reduced the cholesterol profiles. It was obvious that birds on treatment 4 (0.6%) ginger inclusion increased final liveweight and improved the feed conversion ratio (FCR) of turkey poults. It is therefore concluded and recommended that the dietary inclusion of ginger powder meal at 0.6% levels in turkey poults should be adopted by animal nutritionist and farmers.</p> <p><strong>Keywords</strong>: ginger, turkey poults, growth performance, serum biochemistry</p> O.T.

Experimental design was a complete randomized design with three replicates on 4m by 12m bed. Results showed significant (P&lt;0.05) increase in the number of leaves (16.70 – 55.67), leaf length (7.63 – 11.34 cm), leaf width (1.00 – 1.68cm) and plant height (49.34 – 108.40cm) from 8 to 14 WAS. Higher significant (P&lt;0.05) DMY was recorded in 12 WAS (7.47t/ha) and 14 WAS (7.80t/ha). There was a significant (P&lt;0.05) difference in crude protein, crude fibre, neutral detergent fibre, acid detergent fibre, non-fibre carbohydrate, ash, calcium and phosphorus. Significant (P&lt;0.05) values were recorded for dry matter intake, dry matter digestibility and relative feed value across the cutting regimes. Significant difference (P&lt;0.05) was also observed for the methane (CH4) gas production (18.00 – 21.33 ml) and methane reduction percentage (87.88 – 91.67%). Similar (P&gt;0.05) contents were observed for 24 hours’ gas production, in vitro dry matter digestibility, in vitro organic matter digestibility, short chain fatty acid and metabolizable energy across the different cutting regimes. Conclusively, growth pattern and DMY of <em>Centrosema pascuorum</em> across the different cutting regimes 8 – 14 WAS consistently increased, coupled with nutritive parameters and post in vitro characteristics.

Eighteen seven-weeks old male rabbits were randomly distributed into three groups A, B and C each consisting of six rabbits, managed on deep litter and were given maize, sorghum and millet-based diets respectively as their sources of energy and were fed for a period of five weeks before data collection and analysis. Results obtained showed that the dietary treatments significantly (p&lt;0.05) affected the growth performance of rabbits, but not the carcass characteristics, hematology and serum biochemistry. Nevertheless, in all treatments, the red blood cells ranged from 3.52 to 4.61 ×106/mm3 and fell below the normal range (5 – 8 ×106/mm3), while the alkaline phosphatase ranged from 182.67 to 218.57 U/L, and was above the normal range (4 – 20 U/L). It is therefore concluded that the test materials were not toxic to the muscle, kidney and liver of rabbits at 52.21% inclusion level. This implies that sorghum or millet can completely replace maize in rabbit diet with no adverse effect on the hematology and serum biochemistry parameters of rabbits but it may compromise growth.</p> <p><strong>Keywords:</strong> Animal protein consumption, Carcass, Energy sources, Growth performance, Hematology and Rabbits.</p> E.B.

Each group was replicated five times and a replicate comprised seven chicks. The design was 1+ (4 x 3) augmented factorial arrangement in a completely randomized design. The experimental diets were sundried cassava peel meal (SCPM), coarse cassava peel mash (CCPM), whole cassava peel mash (WCPM) and fine cassava peel mash (FCPM) each at three dietary inclusion levels to replace maize at 20, 40 and 60%, while the control diet was a maize-based diet. The diets were fed ad libitum to the respective grower (10-24 days) and finisher (25-46 days) experimental chickens. Results showed no significant effect (p&gt;0.05) of feeding chickens with cassava peel-based diets on carcass primal cuts and internal offals except breast meat and spleen. Breast meat yield (24.90%) of chicks on maize-based diet was significantly higher (p&lt;0.05) than others. Effect of interaction of cassava peel products and inclusion levels on eviscerated weight and breast weight was significant (p&lt;0.05). The eviscerated weight (80.86%) and breast meat yield (24.90%) of chickens on control were higher (p&lt;0.05). In conclusion, replacement of up to 60% dietary maize with cassava peel products had similar effect on broiler carcass yield and productivity but breast yield. Also, further processing of WCPM to FCPM and CCPM did not confer any advantage on chick productivity.</p> <p><strong>Keywords</strong>: Cassava peel, Internal offal, External offal, High-Quality Cassava Peel, Carcass yield</p> S.O.

One hundred and eighty (180) eight weeks old broilers were used. The birds were assigned to six dietary treatments of three replicates each. The experiment was conducted using the Completely Randomized Design (CRD). Each diet represented a treatment. Diet I served as the control free of the test component. The remaining five (5) diets were formulated on 20, 40, 60, 80 and 100 percent substitution levels of matured sun-dried nypa palm fruit nut meal for maize. The diets and water were provided ad libitum throughout the experimental period. Data generated on carcass and visceral organs were analyzed using Analysis of Variance (ANOVA). Results revealed that dressing percentage decreased with increasing level of nypa palm fruit meal substitution. Carcass mean for the drumstick, breast, back and thigh were significantly (P&lt;0.05) different, while the relative weights of the neck and wings were not significantly (P&gt;0.05) different from each other. Weights of the visceral organs for the gizzard, heart, liver, proventriculus, abdominal fats and intestinal weights were significantly (P&lt;0.05) different. However, the relative organs of the kidney, lungs and crop were not significantly (P&gt;0.05) different. Conclusively, the low abdominal fat associated with increase substitution level of nypa palm fruit nut meal for maize is an assurance of good benefit for people with heart related problems.</p> <p><strong>Keywords</strong>: Carcass and organs, characteristics, broiler finisher, matured sun-dried, nypa fruit meal</p> V.E.

Results showed that the main and interaction effects of enzyme supplementation and inclusion level of ECSM did not significantly (p&gt;0.05) influence the growth parameters studied. Enzyme supplementation significantly (p&lt;0.05) increased glucose concentration. Birds fed 5% ECSM based diet recorded the highest globulin value (1.96g/dL). The albumin, globulin and glucose concentration significantly influenced by the interaction effect of enzyme supplementation and ECSM inclusion levels. Birds fed 5% ECSM based diet supplemented with enzymes recorded the highest globulin value (2.02g/dL). Birds fed ECSM based diet supplemented with enzyme had lower (62.22%) lymphocytes value. Interactive effect of ECSM and enzyme supplementation had no influence (p&gt;0.05) on the haematological indices of broiler chicken except the white blood cell and lymphocytes values. The white blood cell and lymphocytes values increased across the dietary treatments as the ECSM supplemented with or without enzyme increased. Main and interactive effects of enzyme supplementation and ECSM inclusion levels significantly (p&lt;0.05) affected the nutrient digestibility. Birds fed diet supplemented with enzyme and those fed 5% ECSM based diet had better nutrient digestibility values.

The rabbits were randomly allotted, 5 each, to five experimental diets, with each animal serving as a replicate. The diets were designated D1, D2, D3, D4 and D5. Diet D1 contained no rice milling by-products and served as the control, D2 contained 20% rice offal, D3 20% rice bran, D4 20% rice grain rejects and D5 10% rice bran + 10% grain rejects. Feed and water were provided ad-libitum. Daily feed intake, daily weight gain and feed conversion ratio (67.94-79.42g, 13.50-15.97g, and 4.71-5.67 respectively) were not affected (p&gt;0.05) by inclusion of rice milling by-products in the diets. Apparent nutrient digestibility indices, except for Nitrogen Free Extract (NFE), were also not influenced (p&gt;0.05) by treatments. NFE digestibility was depressed by the feeding of rice offal (p&lt;0.05). Feed cost per kg of weight gain was highest for the rabbit fed the control diet (₦587/kg) and lowest (p&lt;0.05) for those on diet containing rice bran (₦436/kg). Gross margin between total production cost and revenue was highest for rabbits fed a combination of rice bran and rice grain rejects(₦701.18/rabbit), and lowest (₦561.62/rabbit) for the diet that contained no rice milling by-products. It was, therefore, concluded that the use of these rice milling by-products can be recommended for meat rabbit production.

However, oils are used in formulation without any considerations given to the peculiarities of their innate constituents particularly, vitamin, fatty acids and phytochemicals. Thus, the basis of these determinations. Three lipids: palm kernel oil (PKO), shea butter (SB) and sesame seed oil (SSO), were analyzed chemically in triplicate using standard methods. Results showed that SB had the highest (p&lt;0.05) peroxide value (meq/kg) of 7.4 while PKO (0.7) and SSO (0.3) were similar (p&gt;0.05). The iodine values (g/100g) of the lipids were not significantly different (p&gt;0.05). The saponification value (mgKOH) of PKO (249.9) was significantly higher than SBO (190.9) and SSO (15.8) while the acid value (mgKOH/g) of SBO (10.6) was significantly lower (p&lt;0.05). The α-tocopherol of SBO was 119.2 μg/mL which was significantly higher (p&lt;0.05) than 69.6 μg/mL in SSO and 24.4μg/mL in PKO while there were significant variations (p&lt;0.05) in the fatty acid composition of the oils.

Crop residues and by-products could result in environmental burden or pollution if not recycled or consumed by livestock. Efforts are being geared towards harnessing crop residues or by-products into animal feed. An on-farm experiment was conducted to investigate if fermentation and/or enzyme supplementation would improve the growth response of locally-reared rabbits. The weaner rabbits of similar age were sourced locally and were randomly distributed to groups. The animals were fed ad libitum with commercial basal diet but each treatment group was daily supplemented with 20 g of wheat bran, fermented wheat bran, fermented and enzyme-treated wheat bran, fermented wheat bran and fermented and enzyme-treated cowpea husk accordingly in a completely randomized design. Specific contrasts were also performed. Fermented cowpea husk improved (P&lt;0.05) body weight (day 21) and body weight gain of experimental animals compared with the control group. Other treatments were statistically similar to the control group. The fermentation process improved body weight of experimental animals fed wheat bran diets. The fermentation process enhanced feed intake of experimental rabbits fed wheat bran over the animals fed unfermented wheat bran. Enzyme supplementation improved feed intake of the animals fed wheat bran-based diets. The small intestine of rabbits fed control diet showed normal mucosal layer with normal glands without inflammation (slender arrow), the villi appeared normal (white arrow). The small intestinal photomicrographs of rabbits fed fermented wheat bran-based diet showed mild necrosis and glandular degeneration (black arrow), and the circular muscle layer was normal (grey arrow). The photomicrographs of rabbits fed a fermented cowpea husk-based diet showed normal central venules. The study concluded that fermented cowpea husk could boost rabbit production.</p> <p><strong>Keywords</strong>: crop residue, nutrition, rabbit, sub-Saharan Africa</p> Isaac Oluseun Adejumo, K.A.

This study was conducted to evaluate the effect of tiger nut (Cyperus esculentus) waste (TNW) as feed ingredient on the growth performance and carcass characteristics of broiler chicken. One hundred and twenty day-old Arbor acre strains of broiler chicken were assigned to four treatments with thirty birds per treatment, each treatment had 3 replicates of 10 birds each in a Completely Randomized Design. Dietary treatment included: basal diet + 0.0% TNW (T1), basal diet + 5% TNW (T2) basal diet + 10% TNW (T3) and basal diet + 15% TNW (T4). The study lasted for 7 weeks. Data were collected on growth performance and carcass quality using standard method. Significant means were separated using Duncan multiple range test&nbsp; at p ≤0.05 level of significance. The final weight, feed intake and feed conversion ratio varied significantly (P&lt;0.05) among treatments. Highest feed intake was obtained in T1 (3913.87g) and lowest value in T4 (3720.94g). However, highest weight was obtained in T2 (1825.33g), while the lowest value was obtained in T4 (1600.00g). No Significant (p&gt; 0.05) difference was observed in primal cut part. Highest drumstick value of 10.36% was obtained in T2 and lowest value of 9.00% was obtained in T3. Highest breast weight of 26.73% was obtained in T2 and lowest value of 23.88% in T4. However, there was no significant differences (p&gt;0.05) in organ weight.

A total of fifty four (54) Large White growing pigs with mean weight of 15.33±0.02 kg was placed into three treatment groups based on weight range (Homozygous heavy weight, homozygous light weight and heterozygous weight) for a twenty week study. Eighteen growing pigs served as a treatment group which was further divided into 3 replicate groups of 6 pigs per replicate. At the end of 20<sup>Th</sup> week study, 6 pigs per treatment i.e. 2 pigs per replicate were selected, fasted and slaughtered for carcass yield evaluation. The ham muscle was excised and used to determine pork proximate composition, minerals and lipid profiles. Data collected were subjected 1-way Analysis of Variance utilizing SAS software while significant differences were separated using New Duncan Multiple Range Test as contained in the same statistical package. Result revealed that the prime cut parts (ham, shoulder and puck weights) were significantly higher in homogeneous light weight pigs. Most of ham proximate composition were positively influenced by weight asymmetry. Likewise, weight asymmetry affected total cholesterol, triglycerides, high density lipoprotein, potassium and magnesium values of growing pigs. Heterogeneous weight pigs had highest total cholesterol value of 94.67±2.77 mg/dl and the least value of 85.33±3.41 mg/dl was noted for homogeneous light weight pigs. It can be concluded from this present study that grouping pigs on uniform weight basis especially light weight groups enhanced the welfare of pigs as shown by improvement in pork characteristics and composition.</p> <p><strong>Key words</strong>: Animal; proximate composition; meat yield; pork quality; mineral contents</p> C.P.

A seven weeks trial was conducted to investigate the effect of graded levels of <em>C. papaya</em> leaf meal on broiler growth performance, carcass characteristics, hematological parameters and its anticoccidial properties. A total of one hundred and fifty day-old Marshal broiler chicks were randomly allotted to five dietary treatments with 30 birds per treatment, replicated thrice in a completely randomized design. The treatments were; diet with coccidiostat as a positive control (T1), diet without <em>C. papaya</em> leaf meal nor coccidiostat (T2), diet with 200 g of <em>C. papaya</em> leaf meal/100kg of feed (T3), diet with 400 g <em>C. papaya</em> leaf meal/100kg of feed (T4), and diet with 600 g of <em>C. papaya</em> leaf meal/100kg of feed (T5). The phytochemical component of the <em>C. papaya</em> leaf meal varied from positive to strongly positive. Significant differences (P&lt;0.05) were observed in the final weight, feed intake and the mortality percentage. The best liveability and final weight gain were obtained from the birds fed diets with 400 g of <em>C. papaya</em> leaf meal while non significance differences were observed on the carcass characteristics except on the live weight. The blood profiles were within the normal levels.

Two hundred and forty (240) Anak-2000 broiler chicks aged 6 days were randomly assigned to 12 floor pens containing 20 birds each. Four experimental diets, based on 23 and 20% crude protein in the starter and finisher respectively, were formulated to contain 0, 5, 10,15 % IPPM replacement for maize grain. Each treatment was replicated thrice in a complete randomised design. Data were collected on growth indices, haematological and blood biochemical profile. During the starter period (7-28 days), daily feed intake and feed cost/kg gain were not adversely affected by feeding the test ingredient, but weight gain and feed conversion ratio (FCR) were depressed above 5% replacement of maize with the test material. In the finisher phase (28-63 days), feed intake was significantly increased on the 15% replacement diet compared to the control but did not differ statistically amongst the treatment based diets. The highest daily gain was recorded on the 5% replacement diet, but its values did not differ markedly amongst the control, 10 and 15% diets. Feed conversion ratio was significantly increased above 10% replacement of maize with IPPM/YPM. There was no adverse effect of the test material on haematological and blood biochemical parameters as their values all fell within normal range.</p> E.J. Kpanja, S. Duru, J.A. Kotso, P.T.

Three hundred (300) Ross day old chicks were used for this study. Chicks were randomly allotted to five treatment groups in a complete randomized design having three replicate with twenty birds each. Birds were housed in a deep litter system where water and feed was provided ad-libitum for eight weeks. Five experimental diets were formulated with inclusion of raw and boiled <em>S. obtusifolia</em> seed meal at two different levels 5% and 10% each for raw and boiled respectively. Diets were coded as T1(Control), T2(5% Raw <em>S. obtusifolia</em> seed meal), T3 (10% Raw S. obtusifolia seed meal), T4 (5% Boiled <em>S. obtusifolia</em> seed meal; (BSOSM first user define) and T5(10% Boiled Senna obtusifolia seed meal), respectively. Data collected from this study on growth performance and hematological parameters were analyzed using general linear model of SAS, 2009. Differences among means were separated using Duncan multiple range test. Result obtained from this study shows that there were significant (P&lt;0.05) differences in final weight, weight gain, feed conversion ratio and feed cost/kg gain across treatment groups at the starter and finisher phases. On the other hand, there was no significant (P &gt; 0.05) difference recorded on feed intake, mortality record and all the hematological parameters measured. Birds fed 5% BSOSM had increased weight gain at the starter phase and improved feed conversion ratio in the finisher phase than other treatment groups. Also, birds fed control diet had increased weight gain at the finisher phase and improved feed conversion ratio in the starter phase than other treatment groups. Hematological parameters obtained in this study revealed that there were no significant (p &gt; 0.05) differences across treatment groups.

One hundred and forty four (144) finisher broiler chickens were individually weighed (325±6g) and randomly assigned to four dietary treatment groups of thirty six (36). Each group was replicated three times with each replicate comprising of 12 birds. The design was a complete randomized and the study lasted for eight weeks (8). The dietary treatment groups had T1 (0%), T2 (2%), T3 (4%) and T4 (6%) levels of ginger as feed additive. Data collected were subjected to analysis of variance (ANOVA) and where significant differences occurred, means were separated using least significant difference (LSD). The results showed no significant (P&gt;0.05) difference for final weight, daily feed intake and daily weight gain among the dietary treatment groups.

The bucks were distributed into four treatment groups (n=3), using completely randomised design. Baobab seeds were cooked in boiling water for one hour, sun-dried and crushed into a meal. Four diets were compounded and designated; A (0%), B (25%), C (50%) and D (75%) CBSM. Results showed that there were no significant differences (P&gt;0.05) in all the performance indices measured. The mean daily feed intake values (345.50-367.47 g/day) and mean daily weight gains (7.54-17.06 g/day) were similar (P&gt;0.05) across the treatments. Haematological parameters; packed cell volume, white blood cells, haemoglobin, lymphocytes and neutrophils all showed treatment effect (P&lt;0.05). Treatment effects (P&lt;0.05) were also observed in values of serum albumin, serum glutamic oxaloacetate transaminase and triglyceride among the treatments, however, all the treatment values were within normal ranges. Cooked baobab seed meal up to 75% could be used by farmers as replacement for soybean in the diets of WAD goats with no toxic effects on blood profile or performance.</p> <p><strong>Keywords</strong>: West African dwarf goats, <em>Adansonia digitata</em>, performance, toxic effects, blood profile.</p> J.1⃰.

(cowpea) husk and <i>Gmelina arborea</i> Roxb as basal diet <p>The health implication of Vigna unguiculata L. husk on 20 West African dwarf (WAD) bucks of weights averaging 9.64 kg was investigated in a completely randomized design. Haemato-biochemical profile of the bucks was evaluated in an 84-day study. Four dietary treatments were formulated and compounded to contain 0%, 25%, 50%, and 75% of cowpea husk and these were designated T1, T2, T3 and T4 respectively. Results showed that the packed cell volume (PCV) which was between 29.80 - 34.80% showed significant differences (P&lt;0.05) among the treatment means. T4 (34.80%) was higher (P&lt;0.05) than T2 (29.80%), but similar to the rest treatments. The red blood cells (RBCs) also showed significant difference (P&lt;0.05) among the treatments with a value range of 9.96 - 12.02 x10<sup>6</sup>/μl. The RBCs and haemoglobin values of the bucks in T2 (9.96 x106/μl) and (9.94g/dl) respectively were lower (P&lt;0.05) than the rest treatments. White blood cells (WBC) also showed treatment effect (P&lt;0.05), T1 (11.64 g/dl) was significantly higher (P&lt;0.05) than all the other treatments. All the serum biochemical parameters evaluated were similar (P&gt;0.05) among the treatments. The study demonstrates that inclusion of 75% of cowpea husk in the diets of the buck did not compromise the health of the animals.</p> <p><strong>Keywords</strong>: Cowpea husk, West African dwarf bucks, haematology, serum biochemistry</p> P.L.

A total of 96 lame goats were sampled at the livestock markets, Ibadan, Nigeria. Blood samples were aseptically collected into well labeled heparinized bottles from lame goats with signalment such as breed, age, sex and level of severity classified and recorded appropriately. Blood samples were analyzed by adopting standard hematological procedure (manual counts). Lameness was highest in Red Sokoto goats 79.2% and lowest 8.3% in Crossed bred goats. Majority 66.6% were males and 33.3% were females. Lameness was more in young than adult goats, 2-2½year 41.66% and &gt;4year 20.83%. Significant difference (P≤0.05) observed in the values of lymphocytes between breeds with higher values in crossed breed compared to others. There were significant differences (P&lt;0.05) in the values of RBC and platelet counts between age groups, with lower values of (7.13±0.39 and 3.82±0.2) respectively in adult goats. We therefore conclude that lame cross bred goats appeared more resilient with improved hematological features, significant reduction in RBC and platelet counts should be taken into consideration during management of lameness in adult goats in particular.</p> <p><br><strong>Key words</strong>: Breed; Goats; Haematology; Lameness; Nigeria</p> S.C.

Using Completely Randomised Design, Eighteen (18) West African Dwarf (WAD) goats were used to investigate the performance of goats fed Alchornea cordifolia and Gliricidia sepium leaves supplemented with Pennisetum purpureum. The experimental diet consist of <em>Alcornea cordifolia plus Pennisetum purpureum</em> as diet A, <em>Gliricidia sepium plus Pennisetum purpureum</em> as diet B, and a Concentrate plus Pennisetum purpureum as diet C which served as a control diet. All Data collected during this study were subjected to the Analysis of Variance (ANOVA) and means compared using the Duncan Multiple Range Tests. Goats fed diet A (Alchornea cordifolia plus Pennisetum purpureum) recorded a lower and significant dry matter intake (858g/day) when compared with goats fed Diet B (<em>Gliricidia sepium plus Pennisetum purpureum</em>) (955.33g/day), There was an encouraging weight gain in the various experimental groups. The average weight gain of goats on the experimental diet A (1.22kg), B (1.14kg) and C (1.43kg) were not significantly(p&gt;0.05) different, though goats on the concentrate diet recorded a higher weight gain. On the basis of average weight gain per day (g/day), goats on diet A (<em>Alchornea cordifolia </em>plus<em> Pennisetum purpureum</em>) (13.56g/day) were comparable to goats on diet B (<em>Gliricidia sepium </em>plus<em> Pennisetum purpureum</em>) (12.679g/day).

The study was designed to assess the blood profile of Red Sokoto goats fed a 20 % level of inclusion of baobab seed meal fermented at different duration (24, 48, and 72 hours). Sixteen (16) Red Sokoto bucks with an average weight of 6.96±1.44 kg were used for the study. Four experimental diets were formulated (T1 – T4). T1 was the control diet, while T2, T3, and T4 were 24WFBSM (24 hours water fermented baobab seed meal), 48WFBSM (48 hours water fermented baobab seed meal), and 72WFBSM (72 hours water fermented baobab seed meal), respectively. The experiment lasted for 84 days and was laid in a completely randomized design with four replicates per treatment. The results obtained indicated that the duration of the fermenting period on baobab seed significantly (p&lt;0.05) reduced serum total protein, globulin, zinc, and sodium. Other blood metabolites measured were however not influenced (p&gt;0.05) by the duration period of fermentation. The findings of this study revealed that fermenting baobab seed meal beyond 24 hours is likely to impair some physiological activities of Red Sokoto goats.</p> <p><strong>Keywords</strong>: baobab seed, blood profile, fermentation, Red Sokoto goat</p> T.T.

Animals were fed on grower’s ration (crude protein = 18.06 %) for 10 weeks. Six pigs per treatment (pre- and post-rigor) were slaughtered at the age of 6 months to evaluate pH, shear force tenderness, water-holding capacity (WHC), cooking and storage losses. Data were subjected to General Linear Model in a 2 x 2 factorial arrangement. pH was higher (p&lt;0.05) at pre-rigor state than at post-rigor; while those of the back and thigh muscles did not differ significantly. Rigor state did not influence WHC. Higher shear force (p=0.014) of 2.08 kg were observed at pre-rigor state while a lower value (0.16 kg) was obtained post-rigor. Cooking losses were influenced (p=0.000) by rigor state. Thigh muscle had higher refrigeration and freezing thaw losses. It was concluded that pig meat in post-rigor state could yield better quality product in terms of pH value, shear force, tenderness while minimal cooking and storage losses could be achieved at pre-rigor state.</p> <p><strong>Key words</strong>: pig meat; rigor state; muscle position; shear force; cooking loss; storage stability.</p> G.O.
