Prevalence of hip dysplasia in Boerboel dogs in Nigeria: A retrospective study of radiographic screening between 2016 and 2022

2023-11-01T12:53:09+00:00

Canine hip dysplasia is a complex developmental disease of coxo-femoral joints accounting for 30% of canine orthopaedic cases. Radiological examinations of coxofemoral joints are done to determine the genetic carriers for canine hip dysplasia (CHD) and remove such dogs from breeding. There is scanty record on prevalence of CHD in Boerboel dogs. We reviewed the anterioposterior and flexed lateral hip radiographs of apparently normal Boerboel dogs presented for hip certification between 2016 and 2022 to determine CHD prevalence in the breed. Radiographs were graded using modified Federation Cynologique International grading system. CHD prevalence was expressed as percentages, while age and sex difference in prevalence of CHD were compared using chi-square test. Relative percentages were calculated for CHD grades C, D, and E. Differences were considered significant at p ? 0.05. Median age for the dogs was 2 years with age ranging between 1 and 6 years. 27 (42.2%) were non dysplastic, while 37(57.8%) were dysplastic. Dogs with grade A accounted mostly for the non-dysplastic dogs, while dogs with grade C accounted mostly for dysplastic dogs. HD Prevalence was significantly (p < 0.05) higher in female than male, however, there was no significant (p > 0.05) difference in CHD prevalence between dogs (1 – 2 years of age) and dogs (3 – 6 years of age). Dogs with grade C have the highest relative percentage among the dysplastic grades. It was concluded that CHD prevalence in Boerboel dogs is high and dogs with grade C accounted for most of the CHD cases.

Seroprevalence studies of Infectious Bronchitis Virus (IBV) in chickens in some area council in FCT, Nigeria

2023-11-01T12:57:41+00:00

Avian Infectious Bronchitis (AIB) is a viral disease of serious economic importance characterized by coughing, sneezing, loss of weight and drop in egg and quality. There is paucity of information its occurrence and distribution in Abuja-FCT, Nigeria. Hence this study was conducted to establish the sero-prevalence the virus (IBV) among selected poultry types (local chickens, broilers, pullets, and cockerels) in some area councils within FCT. A total of 360 sera were collected and subjected to Enzyme linked immunosorbent assay (ELISA) at Animal Care Laboratory Nyanya, Abuja. The study found an overall prevalence of 80.56% (290/360). While the distribution according location showed the prevalence of 89.17% (107/120) in Kuje area council, 73.30% (88/120) in AMAC, and 79.10% (95/120) in Kwali area council. The distribution according to type of birds showed prevalence of 74.44% (67/90) for broilers, 78.88% (71/90) for cockerels, 71.11%(64/90) for pullets and 97.77% (88/90) for local chicken. The distribution of IBV occurrence according to management showed that the prevalence bird managed under the deep litter systems was 85.88%, while the prevalence in birds managed under cage system 56.00%. In conclusion, this study found an 80.55% prevalence of infectious bronchitis, associated with increased poultry activities. It is therefore recommended that more public education about infectious bronchitis viral disease be carried out in addition to laboratory diagnosis and other preventive measures.

Evaluation of hoof morphometry in normal and lame polo horses at Ibadan Polo Club.

This study evaluated the changes in hoof morphometric parameters between normal and lame polo horses. Cross-sectional survey of hoof morphometric parameters of polo horses was conducted at the Ibadan Polo club. Also, each horse was physically examined and severity of lameness scored based on the criteria by American Association of Equine Practitioners. Differences in morphometric parameters between sex, lameness status and shoeing status were analyzed using Student’s t test and values were considered significant at p< 0.05) higher in females (118.8 ± 9.3mm; 117.1 ± 8.3mm) than male horses (109.8 ± 6.1 mm; 106.8 ± 12.1 mm). Hoof wall angles did not differ significantly (p > 0.05) between the sexes. Majority of the hoof morphometric parameters were significantly (p< 0.05) higher in shod horses compared to unshod horses. In addition, the dorsal hoof wall angle of the right hind limb was significantly (p < 0.05) higher in lame (61.3 ± 11.50) than normal horses (53.6 ± 8.30). It was concluded that shoeing conditions and lameness significantly alters hoof morphometric parameters of polo horses.

Comparative pregnancy diagnosis of digital rectal palpation technique, ultrasonography, progesterone assay and non-return-to-heat in Red Sokoto goat.

Comparative pregnancy diagnosis was carried out to evaluation the effectiveness of digital rectal palpation technique in Red Sokoto goat, at Small Ruminant Research Program of National Animal Production Research Institute, Shika, Zaria. Forty two does were randomly divided into groups A, B and C, (n = 14 each). Semen was collected from two Red Sokoto bucks using artificial vagina, processed and stored at 4˚C. Oestrus was synchronised with prostaglandin F2-alpha, and oestrus detected by apronised bucks and visual observation. Breeding was by artificial inseminating for groups A and B while group C bred by natural service. Comparative pregnancy diagnosis was carried out using ultrasonography (US) and digital rectal palpation technique (DRP) on day 14, 21, 28 and 126, while progesterone assay (P4) and non-return-to-heat (NRH) on day 21, post-breeding. Pregnancy rates on day 21 were 64.3 %, 92.9 % and 100 % (US); 42.9 %, 57.1 % and 57.1 % (DRP); 78.6 %, 78.6 % and 100 % (P4); 85.7 %, 78.6 % and 92.9 % (NRH). There was significant (P < 0.05) difference between US, DRP, P4 and NRH in groups B and C. It was concluded that DRP technique was effective in early pregnancy diagnosis (days 14, 21, and 28) in Red Sokoto goat does.

Morphological identification of the whizzling sand snake: Psammophis sibilans in Zaria, Northwestern Nigeria

2023-11-01T13:10:03+00:00

Background: Despite extensive research on snakes, although subject to some variation and ignored by many authors, scarce information is available on the morphology of Psammophis Sibilans.

Objectives: This research aimed to study the morphological characterization of Psammophis Sibilans in Zaria, Northwestern Nigeria, as a basis for its morphological identification which may be extrapolated or used as baseline data to show the reliability of scale count in species determination of Psammophis Sibilans.

Methods: Active capture methods were used on free-range snakes and scales were counted to distinguish between the families, generic and specific levels.

Results: The result showed that on the head shield, the loreal [1.0±0.00], pre-nasal[2.0±0.00], internasal[2.0±0.00],preocular[4.0±0.00],supraocular[2.0±0.00],frontal[1.0±0.00], parietal[2.0±0.00] were all the same for all the population studied (n = 20). The dorsal scale [18.00±0.00], and anal plate [1.00±0.00] were also the same for all the snakes studied while the ventral scales [173±2.83], and tail scales [191.30±1.76] showed significant differences within the group. For the zoometric parameters, the body length [85.33±0.44], mid-circumference [7.40±0.10], head length [3.50±0.29], and tail length [32.17±0.17] all showed significant differences within and between the population except for the head width [1.00±0.00].

In conclusion: The head shields are more reliable in the identification of Psamophis sibilans than the zoometric parameters studied, except for the head width. We also discovered a significant variation in the loreal head shield which was just one for all the population studied as opposed to studies from Egypt and Ethiopia where a range of one to two was reported.
