Item This study was designed to evaluate the performance of West African dwarf rams subjected to varying degree of treated velvet bean for a period of 12 weeks. The impact of roasted velvet bean (RVB) on the performance by ram and digestibility of the feed was evaluated. In a randomized complete block design, twelve rams aged 12 and 18 months old with initial weight of 13.67- 14.25kg were randomly allotted into 3 treatments on diets A (0% RVB), B (25% RVB) and C (50% RVB). Weight gain, feed intake and feed conversion were measured. Similarly, in the digestibility trial, 3 animals per treatment were placed in metabolic cages for 14 days of stabilization and 5 days of collection. Treatment effects as affected by varying levels of velvet bean was significant for final live weight gain with values varying from 29.86kg(diet B) to 34.20kg (diet C). Also, the mean live weight gain follows the same trend with the highest mean live weight gain obtained for animals on diet C and the least mean live weight for diet B. The result obtained showed a direct relationship between total feed intake and final live weight gain. Since Mucuna pruriens is available in the dry season therefore, utilization at such period will meet dietary requirement of the sheep.(International Academic Journals, 2013-07) Ososanya, T.

O.; Ososanya, T. O.The haematological characteristics of West African Dwarf (WAD) Rams fed velvet bean (Mucuna pruriens) foliage ensiled with whole maize were determined. Twenty (20) growing rams aged 10-15 months with mean weight ranging between 11.75-12.00kg were randomly assigned to four dietary treatments comprising five animals per dietary treatment in a completely randomized design (CRD). Treatment 1 contained 100% ensiled whole maize, Treatment 2 contained 75% whole maize + 25% Mucunapruriensfoliage silage, Treatment 3 contained 50% whole maize + 50% Mucunapruriensfoliage silage, Treatment 4 contained 25%> whole maize + 75% Mucunapruriensfoliage silage respectively. Each animal receive each diet at 5% body weight for 105 days. Blood was collected through jugular vein and put into well lebelled bottle containing anticoagulant ethylene diaminetetracetic acid (EDTA). The blood samples were analyzed for Red blood cell (RBC) count, Parked cell volume (PCV), haemoglobin (Hb), white blood cell (WBC) count, neutrophils, lymphocytes, eosinophils and monocytes. Significant differences (P<0.05) were obtained in haemoglobin and neutrophil which range from 6.11-9.87g/dl and 35.28 - 41.23% respectively while other parameters investigated showed no significant (P>0.05) differences. The nutritional health status of the rams can be enhanced when fed Mucunapruriensfoliage and whole maize silage but best result could be obtained when fed silage containing 75% whole maize and 25% Mucunapruriens.
