This study was carried out to determine the effect of dietary supplementation of melon (Citrallus lanatus) seed oil (WMO) on the growth performance and immune response of growing rabbits. Thirty-six (36), 5-6 weeks weaner rabbit of mixed breed and sex with an average weight of 435 g – 438 grams were randomly divided into four (4) treatments of nine rabbits per group and each rabbit served as a replicate in a completely randomized design (CRD). The experiment lasted for 12 weeks and all other management practices were strictly observed. The basal diet was formulated according to the nutrient requirements of the rabbit according to NRC (1977). Treatment (T1) was fed basal diet with 0 % WMO, T2, T3, and T4 were fed basal diet supplemented with WMO at 0.2 %, 0.4 % and 0.6 % respectively. Results obtained were used to examine the average daily weight gain (ADWG), average daily feed intake (ADFI), feed: gain, mortality, activities of superoxide dismutase (SOD), glutathione-S-transferase (GST), reduced glutathione (GSH), and malonyl dialdehyde (MLA). ADWG, feed: gain, and mortality were significantly different (P˂0.05) among the treatments. ADFI increased as the level of WMO increases, though not at a significant level (P˃0.05). The highest mortality was recorded among animals in T1 (1.00 %), none was recorded in the other treatments (P˂0.05).  Activities of SOD, GST, GSH, and MLA were significantly (P˃0.05) influenced by WMO. It was concluded that dietary supplementation of WMO up to 0.6 % enhanced growth performance, improved feed: gain, and had no negative effect on the antioxidant parameters of rabbits, it is safe and could be used to bridge the gap between food safety and production.

The purpose of this research work was to evaluate the Aloe vera (Aloe barbadensis) and Yeast (Saccharomyces Cerevisiae)powder. A total of 72 (Arbor-Acres) day old chicks were used in this study. Four levels of anAloe vera and Yeast powder at the rate of 0.00%, 0.50% (Yeast), 0.50% (Aloe vera), and 0.50% Yeast + 0.50% Aloe vera were incorporated into the basal diet for six weeks. Feeding period for all groups was lasted for 42 days. Results revealed a significant effect of Aloe vera and Yeast powder in feeds on weight of breast, thigh, and leg (P<0.05) were significantly on feed supplemented with0.50% Yeast + 0.50% Aloe vera powder. It was concluded from this study that 0.50% Yeast + 0.50% Aloe vera powder feed supplemented has a beneficial impact on the growth of these muscle tissues.

Experiment was conducted on 72-day old chicks of same hatch upto six weeks of age to investigate the effect of Aloe vera (Aloe barbadensis) and Yeast (Saccharomyces Cerevisiae) powder on the hematological parameters of broilers. Chicks were randomly divided into four groups 18 chicks in each. Control group received standard broilers diet. Chicks in second, third, fourth group received standard broilers diet supplemented with the Aloe vera (Aloe barbadensis) and Yeast (Saccharomyces Cerevisiae) powder @ 0.00% (control), 0.50% (Yeast), 0.50% (Aloe vera), and 0.50% Yeast + 0.50% Aloe vera were incorporated into the basal diet for six weeks. At the end of experiment nine broilers from each group should be selected, sacrificed and blood samples should be collected with the help of anticoagulant for determination of hematological parameters. Results revealed a significant effect of Aloe vera and Yeast powder in feeds on mean heterophill (P<0.05) were significantly on feed supplemented with 0.50% Yeast + 0.50% Aloe vera powder. It was concluded from this study that 0.50% Yeast + 0.50% Aloe vera powder feed supplemented has a beneficial impact on the growth performance of broilers chicks.
