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 Influence of water-washed neem fruits (azardirachta indica A. juss) on heamatology and serum biochemical indices of West African dwarf sheep(Science Domain, 2014) Ososanya, T. O.; Adewumi, M. K.; Faniyi, T. O.Neem is a fast growing tree that thrives well in all parts of Nigeria. The seeds are readily available because the plant is used to control desertification. A 4 - week feeding trial was conducted to investigate the effect of supplementation of water - washed neem fruit (Azardirachta indica A.juss) in diets on haematological and serum biochemical indices of West African Dwarf (WAD) ewes. Three diets were formulated to contain water-washed neem fruit at graded levels of inclusion; 0% (control), 5% and 10%. Twelve 10 month old WAD ewes were randomly assigned to 3 dietary treatments. Each treatment had 4 replicates. Variations in values of haematological and serum biochemical parameters of WAD ewes fed experimental diets were determined. Some haematological parameters (RBC and Hb counts) measured were significantly (p<0.05) different while PCV, WBC, some differential counts and serum biochemical parameters were not significantly different among the treatments. However, urea, creatinine, glucose and alkaline phosphatase levels in serum of WAD ewes showed significant (p<0.05) differences, while, other serum biochemical indices measured were not significant. Although, the result of this study showed that the inclusion of water - washed neem fruit at 10% depressed some heamatological parameters, but showed no adverse effect on the ewes. However, all the values obtained for serum biochemical indices were within the normal physiological range except for alkaline phosphatase. Therefore, water - washed neem fruit can be included in the diet of WAD ewes at 10% without any deleterious effect.Item Semen characteristics of pubertal West African dwarf rams fed pineapple waste silage as replacement for dried cassava peel(Academic Journals, 2014-01) Ososanya, T. O.; Adewumi, M. K.; Oyeyemi, M. O.; Adeosun, A. O.In the tropics, ruminants are raised on natural pastures which decline rapidly in quality and quantity during the dry season. This study assessed the reproductive performance of rams fed with cassava–peel–silage (CPS) blended with pineapple-waste (PW) on: scrotal circumference, testicular size and semen volume. Randomized complete block design with four treatments of PW at 0, 20, 40 and 60% w/w in Diets 1, 2, 3 and 4 were used. Each treatment had three replicates while semen was collected once from all replicates in the treatments. Rams were fed experimental diets for 56 days. Cassava-peel was substituted with PW at 0, 20, 40 and 60% w/w in Diets 1, 2, 3 and 4 respectively. Fresh PW were ensiled in plastic mini silos. Samples of freshly processed pineapple waste were taken on the day of ensiling and ensiled products were opened after 21 days to determine their nutritive value. All silage blends had colours from brown to yellow with pH values from 4.0 to 6.8. The scrotal diameter from 16.00cm to 21.40cm and scrotal length from 8.83cm and 12.75cm but did not differ significantly (P>0.05). The sperm motility of rams fed diets 4 and 1 was similar to rams fed other diets. Mean sperm volume, percentage livability and percentage sperm morphology were similar across treatments (P>0.05). It can be concluded that CPS blended with PW up to 60% showed no adverse effect on semen characteristics and fertility of the rams.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 Evaluation of the effects of various additives on the acceptability of kilishi(Animal Science Association of Nigeria, 2003-12) Omojola, A. B.; Isah, O. A.; Adewumi, M. K.; Ogunsola, O. O.; Attah, S.The semitendinosus muscle of hot de-boned beef was trimmed of all visible fats, bones and connective tissue. The cleaned muscle was weighed and sliced into thin sheet of 0.17-0.20cm thick and between 60-80cm long. The sliced meat was infused with locally available spice, condiments and other materials such as salt, sugar, maggi seasoning, peanut paste and water. The local spices and condiments used include; onion, alligator pepper, cloves, chillies, ginger, 'gyadar miya’ (Hausa name), black pepper and spice mixture containing locust bean, groundnut powder and other seasoning. The experiment comprised of six(6) treatments. Treatment one (Tl), served as the control with all ingredients present while ginger, alligator pepper cloves, gyadamiya and black pepper were absent in T2 T3 T4 Ts and T6 respectively. The result of the taste panelist showed that in terms of flavour, the Kilishi where alligator pepper was absent was most preferred. The result also showed that one or two of the spices could replace each other without any marked deference in flavour, juiciness, pungency, tenderness and overall acceptability.
