Item Effect of broiler litter supplementation on reproductive performance of West African dwarf sheep(The Nigerian Society for Animal Production, 2015) Ososanya, T. O.Four low cost feed samples were formulated using 0, 25, 50 and 75% levels of broiler litter processed into feed along with other feed ingredients. Sixteen (16) primiparous West African Dwarf (WAD) ewes aged between twelve and eighteen months old were dewormed using Ivermectin and dipped against ticks and fleas using diazintol. Oestrus was artificially synchronized in all the ewes using 1ml of Prostaglandin - 2Fα administered intramuscularly, the animals were mated with rams of known fertility and lineage bred. Ewes were evaluated in a pregnancy trial while the lambs born were evaluated in a pre-weaning growth trial. All the ewes were weighed before conception and bimonthly thereafter until parturition. The parameters studied were weight at mating, weight before and after parturition, weight changes during pregnancy, weight changes in lactation and nursing, lambs birth weights and daily weight of lambs, dam's weight at weaning and gestation length. Results obtained showed weight at mating, weight before mating, weight at parturition, gestation length, weight gain in pregnancy, weight change in lactation and nursing, lambs birth weights and daily weight gain of lambs were significantly affected (p<0.05) while dam's weight at weaning and lambs' weaning weight were not affected (p>0.05). Results of this study indicate that inclusion of broiler litter up to 50% in feed mixtures of ewes has no deleterious effect on the performance and health status of ewes during pregnancy and lactation.Item Haematological evaluation of pregnant ewes fed broiler-litter based diets(2010) Ososanya, T. O.Blood is a transport medium for the body which plays an active role in sustainability and survival of the organism. Haematological indices reflect the effect of dietary treatments on the animal especially the type and amount of feed ingested and available for the animal to meet its body requirements. A study was carried out for 10 weeks to assess changes in some haematological indices with advancing pregnancy in ewes fed Broiler Litter (BL) based rations. Blood samples were collected at each trimester of pregnancy and analyzed for Packed Cell Volume (PCV), Red Blood Cell (RBC), White Blood Cell (WBC) counts and Haemoglobin (Hb) concentration. Other parameters estimated were: Mean Corpuscular Value (MCV) and Mean Corpuscular Haemoglobin Concentration (MCHC). Results showed that in the first trimester, PCV and Hb. values were significantly higher (P<0.05) in animals fed at 0%, 25%, 50% and 75% BL inclusion levels. In the second trimester, RBC values decreased with increasing levels of BL in the diet while other parameters studied were not significantly different. The findings of this study showed that livestock farmers in the tropics can include broiler litter as feed supplement up to 25% without any adverse effect on the blood chemistry.Item Effect of varying levels of broiler litter on growth performance and nutrient digestibility by West African dwarf lambs(Animal Science Association of Nigeria, 2010-12) Ososanya, T. O.This study investigated the effect of varying levels of broiler litter wastes on growth performance and nutrient digestibility of WAD lambs. Sixteen rams were allotted into 4 groups while 4 experimental diets were formulated using 0, 25, 50 and 75% levels of broiler litter in their diets respectively. The parameters studied included dry matter (DM) intake and nutrient digestibility of the lambs. Results obtained showed that DM intake increased with increasing values of BL in the diet. Similarly, metabolic DMI values obtained were inconsistent with the increasing levels of BL in the diet. All ram lambs gained weight but the rate of gain across the treatments were significantly different (P<0.05) between diets 1 to 3 and 4. Furthermore, it was observed that with the increasing levels of BL in the diet, mean live weight of the animals decreased. Consequently, from the performance of the experimental animals, it can be concluded that broiler litter can be applied in any ruminant production venture as a supplement without any adverse effect at 50% inclusion level.Item Qualities of broiler litter in ruminant feeding(2005-07) Ososanya, T. O.Feed represent a major proportion of the overall production cost in the livestock industry. Availability of good quality and unadulterated conventional feed all year round is a major constraint in livestock production. Also, competition for the same feed resources existing between humans and animals have further compounded the problem leading to overpricing of animal products. Poultry wastes, if properly processed represent a vast reservoir of cheap nutrients especially for ruminants. This study was designed to evaluate broiler litter as a feed for ruminant diets. One hundred and twenty (120) broiler chicks were randomly distributed into three treatments of forty birds each. The birds were fed diets containing 25% crude protein and 23% crude protein at the starter and finisher phases. Litter collected on days 35, 42 and 49 after stocking were sun dried and subjected to proximate analysis to determine crude protein (CP), neutral detergent fibre (NDF) and acid detergent fibre (ADF). The CP, NDF and ADF were: 22.5%, 25.5% and 23.5% for CP, 40.5%, 38.2% and 39.3% for NDF and 21.4%, 20.3% and 20.8% for ADF respectively. However, there were no significant differences (P< 0.05) in the CP and ADF values for the 3 stages of collection. Broiler litter has high protein level which will be efficiently utilized to promote optimum weight gain in ruminants.
