The ingestive behavior and performance of female lambs grazing on Marandu pasture submitted to different stocking rates during the rainy and transition season were evaluated. The experimental area with 4,500 m2 was divided into 45 paddocks of 100 m2. Twenty-seven Santa Ines female lambs (purebred) with 4 months age and 22 kg of initial body weight were distributed in a completely randomized design, with nine replicates. Lambs were divided into 9 groups with the same initial weight and submitted to […]

The objective this study was to evaluate the diurnal ingestive behavior of Nellore steers on Brachiaria grass pasture submitted to protein and energy supplementation. It was used 40 Nellore steers, at initial weight of 373.7 ± 14.9 kg, and at 26 months of age, distributed in four levels of supplementation:mineral mixture, 0.3, 0.6 and 0.9% of body weight of energy and protein supplementation. The animals were visually observed by two 12-hour periods from 6:00 a.m. to 06:00 p.m. Grazing, ruminating […]
