This work was conducted to determine the effects of ammoniation and supplementation on the nutritive value of signal grass (Brachiaria decumbens Stapf) hay. The hay was treated with anhydrous ammonia (3.0% DM) and introduced into the rations for sheep with 12.00% of CP, identified as T1 grass hay without NH3 + cotton seed meal; T2 = treated hay (3.0% de NH3); T3 = treated hay (3.0% de NH3) + com grain meal; T4 = hay + cotton seed meal + corn grain meal. nit: following coefficients of digestibility were determined for T1, T2, T3 e T4, respectively: DM (54.90; 55.50); 54.50; and 56.12%); NI)I: (51.36; 60.20; 55.30; and 48.35%); ADF (47.36; 58.66; 56.03; and 47.07%); hemicellulose (58.80; 63.32; 56.00; and 49.70%); cellulose (55.58; 71.80; 68.07; and 58.21%); lignin (10.10; 32.18; 31.74; and 0.72%) and protein (64.6; 59.36; 56.16; and 70. 15%). nle N balances for T1, T2, T3 and T4 were 5.69; 3.88; 3.90; and 8,82 g N/day. It was concluded that the ammoniation was equivalent to the vegetable protein supplementation in the rations. Furthermore, this treatment showed a greater potential to increase fiber digestion, particulary for ADF and cellulose.

To evaluate the nutritional value of African palm kernel meal (Elaeis guineensis) on the performance of Nile tilapia (Oseochromis niloticus), five isonitrogenous (30% crude protein), isoenergetic (2,800 Kcal/kg of digestible energy), and isofibrous (10% crude fiber) diets, with increasing levels of African palm kernel meal (0, 7, 14, 21, 28 and 35%) were fed ad libitum for 18 weeks to Nile tilapia (Oreochromis niloticus) fingerlings, averaging 1.52 ± 0.04 g of body weight, housed for 120 days in 60 liter aquaria with six fingerlings. To determine the production traits, weight gain, apparent food conversion, specific growth rate, protein efficiency ratio, weight gain percentage, net protein utilization, and body composition, fish were weighted at six-week intervals. Statistical analysis of recorded data were performed through multivariate profile analysis and polynomial regression models. Results showed that feeding fingerling Nile tilapia with ratios containing up to 35% of African palm kernel meal does not affect production performance.
