Item Utilization of graded levels of corn cobs and cowpea husk on growth performance of West African dwarf ewes(2015) Ososanya, T. O.; Alabi, B. O.Corncob (CC) and cowpea husk (CH) are by – products of maize and cowpea production respectively. They can be used as alternative feed resources for ruminants especially during the dry season. A 70d study was conducted to determine the effects of CC and CH based diets on performance of WAD rams. Sixteen ewes were allotted to four feeding regimes: A (100% CC), B (66.7% CC + 33.3%CH), C (33.3% CC + 66.7% CH) and D (100% CH). The sheep were randomly allotted to four diets with four animals per treatment. Digestibility was conducted using metabolic cages which allowed for separate collection of faeces and urine. Samples were analyzed for crude protein and fibre fractions: {acid detergent fibre (ADF), neutral detergent fibre (NDF) and acid detergent lignin (ADL)} using standard procedures. Dry matter intake (DMI), live weight changes (LWG), feed conversion ratio (FCR) and nutrient digestibility were the parameters assessed. DMI ranged from 22.04 kg to 41.07 kg with significant (P < 0.05) differences and LWG ranged from 4.14 gd-1 to 41.71 gd-1 across the diets. Also, FCR ranged from 14.06 in diet C to 45.68 in diet A with significant (P < 0.05) differences across the diets. CP digestibility was highest in diet D (88.01%) and lowest in diet A (72.06%) while ADF, NDF and ADL were highest in diet C and lowest in diet B. However, nutrients digestibility increased with increasing level of cowpea husk in the diets. The result show that highest weight gain and efficient utilization was achieved at 66.7% CH and 33.3% CC inclusion levels.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.

A.; Ososanya, T. O.; Adewumi, M. K.In a growth and digestibility trial with West African dwarf sheep (WAD) the effects of supplementing maize stover with four levels of sweet potato forage (0, 1, 2 and 3% of body weight) on intake and growth rate of the animals; and digestibility of maize stover, sweet potato forage and their mixture were determined using a randomized complete block and completely randomized design, respectively. The dry matter (DM) intake and growth rate of the animals improved significantly (P < 0.01) with increasing level of sweet potato forage in the diet. DM intake was highest at the highest level (3% BW) of sweet potato inclusion and was 140% of the sole maize stover diet. Growth rate of animals at 3% (BW) level of sweet potato supplementation was 195% better than that of animals on sole maize stover. Digestibility of sheep diet improved significantly (P < 0.05) when sweet potato forage formed whole or part of the diet. Addition of sweet potato forage to a basal diet of maize stover improved animal productivity from this fibrous crop residue.
