Biochemical evaluation of Gmelina arborea fruit meal as a swine feedstuff

Azor A. ANNONGU, Abimbola S. FOLORUNSO

Abstract


An experiment was conducted to evaluate the influence of Gmelina arborea fruits (GAF) meal on haematology and certain biochemical parameters including blood enzyme profile of wean pigs. 16-piglets, 8-males and 8-females averaging 12.41 ± 0.59 kg live weight from Hampshire commercial breed were allotted to four dietary treatment groups each consisting of four piglets per treatment group in a completely randomised design. The diets formulated on iso-nitrogenous and iso-energetic basis had Diet 1 containing 30% processed GAF meal and was taken as a reference Diet while Diets 2, 3 and 4 contained 10, 20 and 30% raw GAF meal respectively. The experimental diets and water were supplied to appetite in a feeding trial which lasted for 28 days. There were no statistically significant differences in haematological parameters (p > 0.05) except lymphocytes and neutrophils of the leucocytes differential count (p < 0.05). There were also no significant differences in the selected blood enzymes and serum biochemical parameters of the trial animal models (p >0.05). Urine analyses similarly showed no significant difference in urea and creatinine excretions except that there was a significant difference in uric acid produced (p < 0.05). An overall assessment of the study indicated that values of some parameters measured tended to decrease (in case of blood indices and serum constituents) and increase (with regards to blood urea nitrogen, creatinine in blood and urine and uric acids) though not significantly as the dietary inclusion level of raw GAF meal increased. It was therefore concluded that GAF when processed or incorporated at lower levels has no adverse effect on animals.
