Item Influence of processed neem fruit and yeast mixtures on performance and digestibility of West African Dwarf sheep(Department of Animal Science, University of Ibadan, 2016) Ososanya, T. O.; Adewumi, M. K.; Arowolo, M. A.A feeding trial using sixteen (16) male West African Dwarf (WAD) sheep with an initial live weight of 14.41±2.54kg was conducted to determine the effect of processed neem fruit and yeast supplementation on their performance characteristics and nutrient digestibility. The rams were assigned to four dietary treatments of four rams per treatment consisting of control (T1), yeast alone at 5 g/d (T2), neem fruit alone at 5 g/d (T3) and yeast plus neem fruit at 5 g/d (T4). The dry matter (%) contents were 93.03, 93.04, 93.71 and 93.71 while the crude protein were 8.75%, 8.75%, 10.29% and 10.29% for diets 1, 2, 3 and 4 respectively. Feed at 5% body weight and water were offered in one radon a day. Daily feed intake and body weight changes were determined and feed efficiency calculated. On the 56th day, three rams per treatment were selected for metabolic study. Nutrients digestibility were calculated and computed while nitrogen retention study was determined. Results indicated that yeast and neem fruit supplementation generally improved intake and average daily weight gain in WAD sheep, Aho, DM (56.71, 57.19 and 69.16%) and ME (7.63, 7.47 and 8.05MJ/kgDM) digestibility for diets 2, 3 and 4 differed significantly (P<0.05) from diet 1 (DM 49.74% and M.E 5.55MJ/kgDM). Also, CP digestibility for diet 4 (82.73%) differed significantly (P<0.05) from diets 1, 2 and 3 (72.79, 76.79 and 76.33%) respectively. The DM intake (g/day) across the treatments differed significantly (P<0.05) with the best obtained from animals fed diet 4 (898.32g/d) and the least from animals fed diet 1 (636.06g/d). The best nitrogen retention was obtained from animals fed diet 4 and diet 1 gave the least Addition of yeast and processed neem fruit (T4) promoted average daily weight gain and performance was comparatively better than those on other diets.Item Effect of ammonium sulphate fortification on growth performance, nutrient digestibility and nitrogen balance of West African dwarf rams(2016) Akinlade, A. T.; Ososanya, T. O.Ammonium sulphate (NH(4)2SO(4) is potential source of readily available nitrogen and sulphur which would fill the gap in feed availability to ruminants during the extended annual dry season. Hence, the use of ammonium sulphate becomes a viable alternative to growth-promoting antibiotics due to their effectiveness on ruminant productivity. Therefore, the effect of various inclusion levels of ammonium sulphate on the performance of West African Dwarf (WAD) rams was examined. Sixteen rams weighing 12.8±0.1-2 kg were assigned to four experimental diets containing 0.00, 0.25, 0.50 and 0.75% levels of ammonium sulphate designated as Tl, T2, T3 and T4 respectively. In a completely randomized design, each rams were fed at 5% of their body weight at 60:40 levels of experimental diet and wilted guinea grass as basal diet. The growth trial lasted for 105 days. The chemical composition of the experimental feed and faecal samples were analyzed, and data on total voluntary feed intake, feed conversion ratio, weight gain, nitrogen utilization, and apparent digestibility were also collected. The parameters on proximate composition of the feed were significantly affected by the inclusion of (NH(4)2SO(4) except for DM, GE, Calcium (Ca) and Phosphorus (P). The values for the parameters increased with increased inclusion of (NH(4)2SO(4). The dry matter (DM) and crude protein (CP) obtained ranged from 94.15 - 94.69% and 11.00 - 13.40% respectively while the levels of sulphur was between 4.13 - 4.85%. Live weight gain increased with increased inclusion of (NH(4)2SO(4) and ranged from 3.50 - 5.00 kg but did not differ significantly (P>0.05) from each other. The total voluntary feed intake (TVFI) obtained in this study ranged between 59.79 - 62.64 kg and feed conversion ratio (FCR) from 11.96 - 17.90. However, TVFI and FCR decreased with increasing levels of (NH(4)2SO(4) in the diet. Also, acid detergent lignin digestibility was significantly (P<0.05) affected by inclusion levels of ((NH(4)2SO(4) in the treatments. Nitrogen in feed (3.39g/day), faecal nitrogen output (2.62g/day), urinary nitrogen output (0.21g/day) and nitrogen retention (0.56g/day) were insignificantly (P>0.05) difference except percentage nitrogen retained (16.52g/day) which is significantly different (P<0.05) from each other. It is evident that rams on 0.75% ammonium sulphate supplementation had better growth performance, improved nutrient digestibility and nitrogen metabolism, hence substantiating its utilization in ram diet.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 Nutrient digestibility and rumen fermentation of dried cassava peels and brewers dried grains based diets by West African Dwarf (WAD) sheep(2013) Ososanya, T. O.; Inyang, A. U.In the tropics, supplementing concentrates with grasses, especially during the dry season could improve protein to energy ratio in ruminants thereby improving optimum production. Also, supplementation with a protein source enhances the production capacity of ruminants. Therefore, this study was designed to determine the nutrient digestibility and rumen fermentation kinetics of Panicum maximum supplemented with brewers dried grains and dried cassava peels based diets by West African Dwarf (WAD) lambs. Nine lambs of about 9 months in age and bodyweight ranging from 10.5kg-16.5kg were randomly divided into 3 groups and assigned to the following diets: Diet 1-100% Panicum maximum, Diet 2 - 81% DCP + 13.50% PKC + 2% Oyster shell + 2% Salt + 1.50% Premix and Diet 3-81% BDG + 13.50% PKC + 2% Oyster shell + 2% Salt and 1.50 Premix. Result showed that animals on diet I recorded the least significant (p< 0.05) dry matter digestibility (55.00%) to those on diets 2 and diet 3. Animals on diet 3 recorded the best crude protein digestibility (66.88%) which was significantly different (p<0.05) from those on diets 1 and 2 (53.04% and 56.79%). Animals on diet 1 recorded the highest significant (p<.0.05) amount of ammonia nitrogen at O and 4 hours post feeding. The same trend seems to occur for volatile fatty acids (acetate, propionate and butyrate) at O hour post feeding. However, at 4 hour post feeding, animals on diet 3 recorded a slight numerical advantage over other animals. It can therefore be deduced from this study that diet 3 was most preferred as evident from the Chemical composition of the feed and nutrient digestibility of the lambs.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.; Odubola, O. T.; Shuaib-Rahim, A.Dried cassava peels (DCP), wheat offal (WO) and palm kernel oil (PKO) are readily available in the tropics during the dry season. Sixteen rams aged 15 months with weight range of 11.07 ±0.8kg were randomly divided into four treatments with four replicates in a CRD. The treatments were: T1 - 100% DCP, T2 - 80% DCP + 20% WO, T3 - 77% DCP + 20% WO + 3% PKO and T4 - 97% DCP + 3% PKO. Parameters studied were feed intake, nutrient digestibility, total volatile fatty acids and microbial population. The dry matter intake values obtained were 869.98, 8415.89, 784.36 and 462.16g/dl for Tl, T2, T3 and T4 respectively with significant differences (P < 0.05) between Tl — T3 against T4. Nutrient digestibility had significant differences (P < 0.05) amongst treatments for all parameters studied except in Neutral detergent fibre with no significance. The dry matter digestibility increased from 82.61% in Tl to 91.12% in T4, crude protein digestibility ranged from 82.89% to 89.98% for Tl and T2 respectively. There were no significant differences (P > 0.05) between T2 and T4, also between T3 and T4. Hemi cellulose appeared to be the most digestible nutrient studied. Rumen pH ranged from 6.00 to 6.70 for T2 and T4 respectively. The result was similar (P > 0.05) statistically across the treatments, except in T2. Ammonia nitrogen increased with supplementation of WO and PKO. However, supplementation of DCP with WO and PKO at 3% inclusion improved digestibility, but depressed feed intake in WAD sheep.Item Utilization of sweet potato as a forage supplement to a maize stover diet by West African dwarf sheep(Animal Science Association of Nigeria, 2005) Olorunnisomo, O. 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.Item Effect of Ad-libitum, split and restricted feeding on performance, digestibility and welfare of broiler chicken(Sciencedomain International, 2017) Adeyemo, G. O.; Badmus, R. T.; Longe, O. G.; Ologhobo, A. D.An experiment was conducted to assess the performance, welfare and digestibility of broilers fed varying forms of feeding regimes. The objective of this work research was investigate the possibility of improving growth performances, digestibility and welfare of broilers using ad libitum, split and restricted feeding. Formulated diet was given in four different forms Ad-libitum (Treatment 1) twice a day meal/split feeding (Treatment 2) thrice a day feeding (Treatment 3) 3 hours restriction feeding (Treatment 4). Experimental design was completely randomized design. 240 broilers were randomly allotted to four treatments with 6 replicates and 10 birds per replicate. Birds were weighed weekly to evaluate their performances, faeces was collected on day 42, to determine digestibility and rectal temperature was taken as a measure of bird's wellbeing. Results showed that there were no significant differences (p≥ 0.05) in performance of birds across treatments but values from birds fed Ad-libitum were higher. Rectal temperature (RT) differ at week 4, birds fed 3 hours restricted feeding had the highest RT (41.62°C) while the least RT were from birds fed Ad-libitum (41.20°C). Significant differences were obtained in digestibility and nutrient utilization of broilers with respect to feeding regimes. Crude protein (CP) digestibility was significantly higher in birds fed 3 hours restriction (81.91%) while birds fed Ad-libitum had the least (46.76%). The digestibility of crude fibre was higher in birds fed 3 hours restricted feeding regime (86.77%) the least was from birds fed thrice a day feeding regime (62.66%). A similar trend was obtained for digestibility of gross energy. Ad-libitum feeding had the highest non-significant performance values but split feeding optimized feed and nutrient utilization thereby enhancing performance and minimizing nutrient waste at the same time.
