The objective of this study was to evaluate the effect of inclusion of lipid residue of biodiesel originated in the processing of palm oil (Elaeis guineensis) in the diet on the digestibility of feedlot lambs. Twenty-five crossbred male castrated lambs, weighing 20±1.61 kg, were distributed in randomized blocks with five treatments and five replications. The experimental period lasted 22 days; 15 for diet adaptation, 2 for the adaptation to the indicator LIPE (lignin from Eucalyptus grandis isolated, purified and enriched, […]

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 […]

This trial aimed to describe and compare the feeding behavior of Jersey cows at the beginning of lactation and fed diets with different fat sources. Fat sources tested were tallow, calcium salts of palm oil and ground soybean, representing sources of mainly saturated, unsaturated-protected and unsaturated fats, respectively. Eight cows weighing 389±27 kg, with body condition score from 3 to 3.5 and yielding 21.8±3.5 L/day, were used. Animals were randomly allocated to treatments according to a replicated Latin square design, […]
