K.; Belewu, M. A.; Adeyina, A. O.; Akanbi, A. S.; Yusuff, A. T.; Sola-Ojo, F. E.; Ajide, S. O; Chimezie, V. O.; Edoh, J. H.Native de-oiled and treated castor seed meal was subjected to proximate analysis and quantification of antinutrients (phytochemicals). Seed cake was treated by biochemical technique of solid state fermentation with Aspergillus niger and addition of calcium oxide (CaO) to give treated castor seed meal (TCSM). One hundred and twenty Japanese quails (Coturnix coturnix japonica) were fed four (4) iso-nitrogemous and iso-caloric diets containing 0, 2.5, 5.0 and 7.5% TCSM corresponding to the diet 1, 2, 3 and 4, respectively. While the feeding trial lasted for 56 days, feed and water were supplied ad libitum. Data on proximate composition showed that raw seed, defatted residue (cake) and the processed castor seed meal contained valuable nutrients like dry matter, crude protein, fat, fibre, mineral matter and soluble carbohydrate (NFE). Phytochemical quantification gave high levels of the anti-nutrients such as ricin, allergens, ricinine in the raw seed. However, levels of these phytochemicals were reduced by defatting and treatments of the cake meal by solid state fermentation, A. niger and CaO. Performance traits indicated decreases in feed intake, weight gain, growth and increases in mortality rates especially on the diet with the highest (7.5%) inclusion of TCSM compared to the control diet (P<0.05). Nutrients retentions on the test feedstuff were not comparable with values on the reference diet on soluble carbohydrate values which decreased with increasing CSM (P<0.05) relative to the control diet. In haematological parameters packed cell volume (PCV) and mean corpuscular hemoglobin (MCH) values on diets with TCSM were exceptionally high relative to the control diet (P<0.05). However, biochemical indices (serum protein, albumin, globulin, albumin:globulin ratio and alkaline phosphatase (ALP) activities were not influenced by dietary CSM (P>0.05). Enzyme activity of aspartate aminotransferase (AST) showed decreasing trend with increasing level of CSM in diets (P<0.05). Profiling electrolytes in the fed quails showed significant variations in concentrations of Ca++ and HCO3 - on TCSM based diets (P<0.05) comparable with the control diet values. Conclusively, despite treating CSM by solid state fermentation with A. niger and CaO addition in this trial, TCSM addition still appears to induce toxic and deleterious effects on the quails. Subsequent works to enable inclusions at acceptable and higher levels after treatments are on-going.Item Somatic cell and cheesemaking variables of WAD goat milk: Influence of parity and lactation stage(Faculty of Animal Science, Bogor Agricultural University, Indonesia., 2021) Yusuff, A. T.; Badmos, A. A.; Awofadeju, E. V.; Akintunde, A. A.; Alli, O. I.; Chimezie, V. O.; Fayeye, T. R.The suitability of any goat breed for dairy purposes depends on its assessment of milk-related traits. This study evaluates the influence of parity and lactation stage on somatic cell count (SCC) and cheese-making variables of West African Dwarf (WAD) goat milk. A total of 48 lactating WAD does of three different parities (the 1st, 2nd, and 3rd) were milked over a period of time-phased into three stages of lactation (early, mid, and late). The milk was subjected to SCC and cheese-making during which coagulation time, cheese yield (CY), whey volume, and whey pH were recorded. Collected data were subjected to analysis of variance and Pearsons’ correlation. The result revealed that the milk SCC of the does in the 3rd parity (2.16 x 105 cells) was significantly (p<0.05) higher than 1.89 x 105 and 1.87 x 105 cells in the milk of the 1st and the 2nd parity does respectively. There was a similar variation trend of SCC as lactation progresses in each of the parities. The CY significantly increased (p<0.05) as lactation progresses in the 1st parity (early – 16.95%; mid – 17.21%; late – 20.85%) while, the milk of the 2nd and the 3rd parity from mid to late lactation stage yielded statistically similar cheese that was comparable with late lactation CY of the 1st parity does. The lactation stage and SCC were positively correlated with CY. The volume and pH of the whey were neither affected by the lactation stage nor parity. The study concludes that parity uncovers the effect of lactation stage on the milk SCC of WAD does while the milk obtained from mid to late lactation stage yields more cheese.Item Sperm characteristics of Nigerian Local Cocks and Exotic Strain of Cocks fed Graded Levels of Moringa Oleifera Seed Meal.(Department of Animal Science, University of Ibadan., 2020) Akintunde, A.
