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 Intake, nutrient digestibility and rumen ecology of West African dwarf sheep fed palm kernel oil and wheat offal supplemented diets(International Academic Journals, 2013-05) 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 Reports on the prevalence of pneumo - enteritis among sheep in Ile- Ife, Nigeria(2012) Afolabi, K. D.; Ososanya, T. O.; Alabi, O. M.; Balogun, O. L.Data were collected on the prevalence of pneumo-enteritis among 895 sheep reared ori the semi-intensive system at Obafemi Awolowo University Teaching and Research (OAUTR) farm, lle-Ife and 317 sheep brought from the free range for sale at Ile-lfe Sheep and Goat [ISG] market between the periods of December 1985 to October 1993 and November to October 1993 respectively. At OAUTR farm, 39.51% of the sheep were affected with pneumo-enteritis; 78.13% of the treated sheep [32 in number) recovered while 6.26% mortality was obtained. At ISG market 33.10% of the sheep were affected. The disease was more prevalent during the dry seasons (November to March) at OAUTR farm (9.96%) and ISG market (69.33%) than what obtained during the rainy season (April to October) at the two locations (8.08% and 21.90% respectively). The incidence of the disease was higher among sheep at ISG market than those at OAUTR farm. Bacteriological examination of nasal swabs from infected sheep revealed the presence of Pasteurella haemolytica, Pasteurella multocidci, Streptococci spp. and Coccobacillia bacteria. Prompt treatment of infected sheep elicited recovery.
