Description
Summary:The aim of this study was to evaluate the linear correlations between feeding behavior and apparent digestibility in feedlot lambs. Fifty castrated Santa Inês ram lambs with an average body weight of 20 ± 4.38 kg and four months of age were used in this experiment. Animals received different feed levels aiming at promoting variations in feed intake and apparent digestibility. A randomized complete design was adopted. Digestibility and feeding behavior were measured. Analyses were performed using Pearson’s linear correlations, applying the t test at 5% probability level. A positive correlation was detected between feeding time and apparent digestibility of ether extract and total digestible nutrients (TDN) (p Objetivou-se avaliar as correlações lineares do comportamento ingestivo e a digestibilidade aparente em borregos confinados. Foram utilizados 50 ovinos machos, castrados, da raça Santa Inês, com peso corporal médio de 20 ± 4,38 kg e quatro meses de idade. Os animais receberam níveis de oferta de dieta com o objetivo de promover variações no consumo alimentar e digestibilidade aparente. Foram mensurados a digestibilidade e o comportamento ingestivo dos animais. As análises foram realizadas usando correlações lineares de Pearson utilizando o teste t, a 5% de probabilidade. Verificou-se correlação positiva do tempo de alimentação e a digestibilidade aparente de extrato etéreo e os nutrientes digestíveis totais (NDT) (p
