          Abstract

          The objective of this work was to evaluate the effects of supplemental feeding of soy waste on the feed intake and growth rate of goats. Twenty male crossbred (Boer x local) goats were assigned to two isonitrogenous diet groups: one of commercial pellet and the other of soy waste. The commercial pellet (1.0%) and soy waste (0.8%) were provided on the dry matter basis of body weight (BW) per day, to the respective group of each diet. The soy waste group had lower daily intakes of total dry matter (0.79 vs. 0.88 kg) and organic matter (665.71 vs. 790.44 g) than the group fed pellet; however, the differences on daily intakes for grass (0.62 vs. 0.64 kg), crude protein (96.81 vs. 96.83 g), and neutral detergent fibre (483.70 vs. 499.86 g) were not significant. No differences were observed between groups for BW gain. The feed conversion ratio and feed cost per kilogram of BW gain were lower for the group fed soy waste than for the one fed pellet. Goats fed supplemental soy waste have a lower total dry matter intake, feed conversion ratio, and feed cost per kilogram of body weight gain than those fed commercial pellets.

          O objetivo deste trabalho foi avaliar os efeitos da alimentação suplementada com resíduos de soja sobre o consumo alimentar e a taxa de crescimento de cabras. Vinte machos de cabras cruzadas (Boer x local) foram designados a dois grupos de dieta isonitrogenada: um de pélete comercial e outro de resíduos de soja. O pélete comercial (1,0%) e os resíduos de soja (0,8%) foram fornecidos, com base na matéria seca da massa corporal por dia, ao grupo respectivo a cada dieta. O grupo da dieta com resíduos de soja apresentou menor consumo diário de massa de matéria seca total (0,79 vs. 0,88 kg) e de matéria orgânica (665,71 vs. 790,44 g) do que o grupo alimentado com pélete; no entanto, as diferenças de consumo diário de gramínea (0,62 vs. 0,64 kg), proteína bruta (96,81 vs. 96,83 g) e fibra em detergente neutro (483,70 vs. 499,86 g) não foram significativas. Não se observaram diferenças entre os grupos quanto ao ganho de massa corporal. A taxa de conversão alimentar e o custo do alimento por quilograma de ganho de massa corporal foram menores no grupo alimentado com resíduos de soja do que no alimentado com pélete. Cabras suplementadas com resíduo de soja apresentaram menores consumo total de matéria seca, conversão alimentar e custo da ração por quilograma de peso vivo do que as suplementadas com ração comercial.
