Twenty-four Saanen goats, 15 multiparous and nine primiparous, were distributed in a completely randomised design in a factorial arrangement (3 diets × 2 parities). The treatments were soybean meal (SB), soybean + dry yeast (SBDY), or dry yeast (DY) as a protein source in the diet, and ground corn, mineral supplement, and corn silage (400 g/kg). The study was conducted to evaluate the nutritive value of diets containing inactive dry yeast as a protein source postpartum, postpeak, and during late […]

The rumen fermentative characteristics of Nelore steers grazing Brachiaria Brizantha pastures (Teste), or supplemented during the dry season (Seca), dry and wet seasons (Ano) or with free access to a Leucaena bank (Banco), in a randomized block design with four replications, were evaluated. The dry season supplement had 46.9% CP, 70% rumen degradable, and the wet season supplement, 43.9%CP, 60% degradable. Rumen liquor was collected on August, November, February and May. The molar proportions of propionic acid in the supplemented […]

The supplementation of more digestible starch sources and feed additives with coccidiostatic and growth promoting activities may improve pre and post weaning calves performance. The objective of this trial was to evaluate the effects of concentrates containing processed grains (steam-flaked vs. steam-rolled), with or without monensin, on intake, weight gain and blood parameters of baby calves, before and after weaning at six weeks of life. Thirty-two female calves were utilized on a completely randomized block, with a 2 x 2 […]
