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.

Feeding trial experiment was carried out to evaluate the haematological and serum biochemical parameters of broiler chickens fed graded levels of Roselle Seed Cake (RSC) as replacement of a conventional protein source. Proximate composition was done to determine the nutrient content of RSC and experimental diets. The experiment contained graded levels of RSC replacing soya bean cake (SBC). One hundred and twenty (120) day old Ross broiler chickens were used in a Completely Randomized Design (CRD). The broiler chicks were assigned to five dietary treatments with three replicates each with 8 birds per replicate and 24 birds per treatment. Five isonitrogenous and isocaloric diets were formulated for the broiler straight diet. Diet 1 served asthe control diet while diets 2, 3, 4 and 5 contained 8%, 16%, 24% and 32% RSC respectively. Data were collected and analyzed using analysis of variance and the mean was separated using Duncan multiple range test. The findings from the study showed that there were no significant (P?0.05) differences in all the parameters measured for haematology across dietary treatment means except for the white blood cell. The blood biochemical composition showed no significant (P?0.05) differences in total protein, high density lipoprotein, low density lipoprotein and creatinine across dietary treatments. RSC as an alternative feedstuff can replace soya bean cake at 24% in the diet of broiler chickens for improved haematological and blood biochemical of broilers. Roselle seed cake can replace SBC at the broiler chicken straight ration at 75% (24% dietary RSC) inclusion for better performance.

Researches have proven that garlic has medicinal, antimicrobial properties, speeds up digestion and widely used as preservatives, spice and condiment in many homes Vitamin E on the 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 physiological response of garlic and vitamin E supplementations on libido, gonadal and extra-gonadal sperm characteristics, reproductive hormone and testicular histology of rabbit bucks. The bucks were randomly assigned to four dietary treatments and replicated three times in a completely randomized design (CRD). Each dietary treatment consisted of 9 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 (T1), 3% garlic (T2), Vitamin E (T3), and 3% garlic and Vitamin E (T4) respectively. Data were collected on the libido, seminal characteristics, seminal plasma, testicular morphology and hormones. The testicles were collected and processed for histopathology. Data collected on different parameters were subjected to analysis of variance (ANOVA). Results showed that significantly (P<0.05) differences were observed in all the seminal characteristics parameters, on the testicular weights, volumes and on the reproductive hormones compared with the control. Testicular histology showed increased in number of seminiferous tubules with the supplementation. These results proved that both garlic and Vitamin E improve semen production both in quality and quantity and the overall reproductive performance. Moreover, combination of the garlic and vitamin E gives a better result. Therefore, garlic and vitamin E should be used together for better quantitative and qualitative semen production and reproductive performance in breeding animals

This study was carried out to evaluate the haematological and blood biochemical parameters of broiler chickens fed graded levels of Roselle Seed Cake (RSC) diet as replacement for groundnut cake (GNC). Proximate composition of the test diet and experimental diets were conducted to determine their nutrient contents. Four diets were formulated for the broiler chickens. The Diet 1 served as the control diet while diets 2, 3 and 4 contained 8%, 16% and 24% with Roselle seed cake (RSC) diets respectively as replacement for groundnut cake (GNC). A total of 120, one day-old Ross broiler chicks were randomly allotted to four dietary treatments with four replicates and each treatment consisted of 30 birds in a Completely Randomized Design (CRD). Feed and water were provided for the birds ad libitum. The blood parameters measured are haemoglobin, packed cell volume, red blood cell, white blood cell, heteropils, lymphocytes, monocytes, eosinophils, basophils and band cell. The results from the parameters measured for blood quality showed no significant (P?0.05) differences for haemoglobin level, packed cell volume (PCV), white blood cell (WBC), across the treatments. But the red blood cell (RBC), heterophils and lymphocytes had a significant difference across the dietary treatments and this implies that Roselle seed cake (RSC) inclusions in the diets of the birds had a positive effect on the oxygen carrying capacity, immunity level and antibodies producing capacity of the birds. The blood biochemical parameters measured are total protein, albumin, cholesterol, creatinine, triglycerides, HDL and LDL. The parameters measured showed no significant (P?0.05) differences in total protein (TP), creatinine, high density level (HDL) and low density level (LDL) across dietary treatment while albumin and cholesterol had significant differences (p>0.05) across the dietary treatments. RSC can replace GNC at 16% dietary inclusion levels.
