Digestibilidade de Nutrientes em Dietas com Fubá de Milho e Resíduo de Pastifício, em ovinos

Abstract

The objective was to analyze the apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and ethereal extract (EE) of different doses of the pasta residue in the nutrition of sheeps replacing corn bran. The animals were not castrated males, mixed breed, aged approximately six months, average weight of 30.0 ± 3.0 kg. There were six treatments with four replications (24 plots) : S = 100% corn silage, 40s/60c = 40% corn silage + 60% ground corn, 40s/60r = 40% corn silage + 60% residue, 40s/45c/15r = 40% corn silage + 45% ground corn + 15% residue, 40s/30c/30r = 40% corn silage + 30% ground corn + 30% residue, and 40s/15c/45r = 40% corn silage + 15% ground corn + 45% residue. The treatment with higher dose of residue showed higher digestibility of DM (40s/15c/45r = 89,93%; 40s/60r = 90,71%), OM (40s/15c/45r = 89,31%; 40s/60r = 89,57%) and CP (40s/15c/45r = 58,01%; 40s/60r = 59,96%). The NDF had a higher digestibility only at treatment composed just with the residue (40s/60r = 60,51%). The ADF had, in all the treatments that included residue, increased the fiber digestibility. For the EE, differences of digestibility were not observed between the treatments using concentrated. The inclusion of pasta residue replacing the corn bran is recommended in diets for sheeps.
