Effects of garlic (Allium sativum ) and vitamin E on blood profile, growth performance and internal organ characteristics of rabbit bucks

Abstract

Studies have shown that garlic has medicinal, antimicrobial properties, speeds up digestion and widely used as preservatives, spice and condimentin many homes. Vitamin E on the other hand is a fat soluble vitamin with potent antioxidant properties essential for the stabilization of biological membranes, protecting cells from oxidative stress and inhibits angiogenesis. Thus, a study using thirty-six (36) pre-pubertal New Zealand White rabbit bucks was conducted to investigate the response of garlic and vitamin E supplementation on haematological indices, serum biochemistry and growth performance. The bucks were randomly assigned to four dietary treatments and replicated three times in a completely randomized design (CRD). Each dietary treatment consisted of rabbits per treatment with 3 rabbits per replicate. Four dietary treatments were formulated to meet the nutrient requirements of rabbits supplemented at 0% garlic and vitamin E (T ), 3% garlic (T ), Vitamin E (T ), and 3% garlic and Vitamin E (T ) respectively. Data collected on the growth performance, haematology and serum biochemistry parameters and on the internal organ characteristics were subjected to analysis of variance (ANOVA). Results showed that significantincrease (P<0.05) were observed in final body weight, ear length, forelimb, hind- limb and body length for rabbits fed supplementation of garlic, vitamin E and its combination, while tail length, head to shoulder significantly decreases. Hematological parameters showed significant increases in red blood cellcount for vitaminE group while T was higher on MCHC. White blood cell and its differentials increased significantly on T, T and T Serum biochemical characteristics were significantly higher on total protein, globulin and creatinine; while cholesterol, glucose and ALP reduced significantly on T , T and T  It could be concluded that combination of garlic and vitamin E improved performance and blood profile of rabbit bucks compared to when they are used individually.
