The nutrients digestibility, nitrogen utilization and blood profile of West African Dwarf (WAD) goat fed cassava peels with urea-molasses multi-nutrients block (UMMB) supplements was investigated in a twelve weeks experiment. Twenty WAD goats that weighed 8.33±0.35 kg on average were assigned to each of the five experimental diets that contained cassava peels without UMMB supplement (treatment 1) and with UMMB containing 0% urea (treatment 2), 5% urea (treatment 3), 10% urea (treatment 4) and 15% urea (treatment 5), in a completely randomized design (CRD). Results of the study revealed that nutrients digestibility were significantly (P<0.05) influenced by UMMB supplementation. Goats fed diet T 4 also had the highest values of digestibility coefficients of dry matter (DM), crude protein (CP), crude fibre (CF) and nitrogen free extract (83.05%, 71.97%, 67.64% and 71.34%) respectively. Nitrogen retention was significantly (P<0.

Uses of exogenous growth a promoter are safe, improve performance and reduce production costs in poultry business. Our objectives were to evaluate the influence of dietary crude testosterone (CTE) inclusion on growth, performance and carcass yield of broilers fed standard-and low-protein diets. One hundred and eighty day-old Marshall strain of broiler chicks were randomly assigned to six treatments; T1, T2, T3, T4, T5 and T6. T1 served as control (for standard-protein diet (SPD)) without CTE. T2 were fed SPD with CTE inclusion for 8 weeks. T3 were fed SPD with inclusion of CTE during the finisher phase only (4 weeks). T4 was control for low-protein diet (LPD) without CTE inclusion for 8 weeks. T5 were fed LPD with CTE inclusion for 8 weeks and T6 were fed LPD with the inclusion of CTE at the finisher phase only. Birds had ad libitum access to feed, water, and routine medications were administered. Feed intake, water intake, feed conversion ratio, body weight gain including carcass yield were measured and analyzed according to procedures of SAS. The results of the experiment showed that there were significant differences (P < 0.05) in all parameters measured except mortality, thigh, drumstick, proventriculus, neck and gizzard. However, birds on T2 performed best by attaining a live weight of 2098.00 g at 8 weeks and a FCR of 2.07. Profit per bird was significantly (P < 0.05) influenced. Therefore, inclusion of CTE as growth promoter in commercial broiler production with low-protein diet can be adopted for profitable broiler production.
