Description
Summary:The objective of this study was to evaluate the effect of increasing levels of the substitution of sorghum silage by wet brewery grains (WBG) on the feeding behavior of feedlot finished lambs. Twenty-four Suffolk breed single birth non-castrated male lambs were maintained in individual stalls. The treatments consisted of four substitution levels of sorghum silage by WBG: 0 %; 33.5 %; 66.5 % or 100 %. Roughage and concentrate at 50:50 ratio were used, basing on dry matter. The concentrate was composed of ground corn, soybean meal and mineral mixture. The diets were isoproteic containing 18.81 % CP. The time used on feeding, rumination and total chewing activity decreased (P0.05), averaging 1.371 and 0.466 Kg/day, respectively. WBG level in diets linearly increased (P = 0.05) daily weight gain of the animals. Rumination efficiency linearly increased (p O objetivo deste estudo foi avaliar o efeito de níveis crescentes de substituição da silagem de sorgo por resíduo úmido de cervejaria (RUC) sobre o comportamento ingestivo de cordeiros terminados em confinamento. Foram utilizados 24 cordeiros machos, não castrados, da raça Suffolk, oriundos de parto simples e mantidos em baias individuais. Os tratamentos foram constituídos por quatro níveis de substituição de silagem de sorgo por resíduo úmido de cervejaria sendo: 0 %; 33,5 %; 66,5 % e 100 %. Utilizou-se uma relação volumoso: concentrado de 50:50, com base na matéria seca. O concentrado era constituído por milho desintegrado, farelo de soja e mistura mineral. As dietas eram isoprotéicas contendo 18,81 % de proteína bruta (PB). Os tempos despendidos com alimentação, ruminação e mastigação total diminuíram linearmente (p
