Consumo e parâmetros produtivos de ovelhas gestantes suplementadas com concentrado

Abstract

The effect of concentrate supplementation on pregnancy and dry matter intake of ewes was evaluated. 41 animals were used, with 64.18 kg of average weight, distributed in a completely randomized design with repeated measures over time. The treatments consisted of two levels of concentrate. Analysis of variance and Tukey's test were performed at 5% of significance. There was an increase in consumption and body weight throughout the period. There was an effect of supplementation on placental weight, being superior in the treatment with 400g, and in multiple deliveries. Supplementation of pregnant ewes in the prepartum period improved BCS as well as birth weight of the lambs.
