ABSTRACT This study was conducted to investigate the effect of selective feeding habits on the quality of the ingested diet and the effect of feed restriction on the selectivity and behavior of goats in feedlots. Differences were found only in the amount of feed given to the animals, with a difference in the amount of feed rejected as a function of the nutritional level. Higher levels of orts were measured for those animals that received the ad libitum diet. For […]

Two digestibility trials were carried out, to study the nutritional value of four types of pearl millet (BN2, Comum, Iapar and Iapar-Repasse), grounded through 3, 2, and 1 mm screen. The digestibility coefficient (DC) of gross energy (GEDC) and gross energy metabolization coefficient (GEMC) relative to 3 mm screen were: 63.09 and 61.20% (Comum); 71.57 and 69.66% (Iapar) and 67.39 and 65.60% (BN2). The GEDC and GEMC of COMUM were lower than IAPAR and both were similar to BN2. The […]
