Cama de frango e suplemento à base de microbiota ruminal em dietas de novilhas leiteiras: desempenho produtivo e avaliação econômica

Abstract: O trabalho foi conduzido para avaliar o desempenho de novilhas de rebanhos leiteiros recebendo dietas contendo cama-de-frango (CF) e suplemento à base de microbiota ruminal (SMR). Foram utilizadas 20 novilhas mestiças Holandês-zebu, com peso médio inicial de 276 kg e idade média de 13,8 meses. Os animais foram distribuídos aleatoriamente em arranjo fatorial 2x2, no qual foram estudados dois níveis de CF (15 e 30% na matéria seca) e de SMR (0 e 10 g/animal/dia), em delineamento inteiramente casualizado, com cin… Show more
