Abstract

GONCALVES, João Arlindo Gouveia et al. Silage from residue from extraction of cassava starch in substitution of ground corn in sheep feed. Rev. bras. saúde prod. anim. [online]. 2015, vol.16, n.4, pp.839-849. ISSN 1519-9940.  http://dx.doi.org/10.1590/S1519-99402015000400008.

With aimto evaluate the effect of replacing the ground grain corn for silage of waste resulting from the extraction of cassava starch in diets for sheep in confinement, was measured the consumption, the digestibility of dry matter and nutrients, and the rumen pH. Were used five cannulated sheep, distributed in outline Latin square (5 x 5), composed of five animals, five diets and five experimental periods of 21 days, for a total of 105 days of experiment. The treatments were different levels of substitution (0, 25, 50, 75, 100%) of maize for silage of waste resulting from the extraction of cassava starch. The replacement levels obtained significant difference, obtaining cubic variation for the intake of dry matter (DM), crude protein (CP), organic matter (OM), ether extract (EE)and total carbohydrates (TC), and quadratic effect for neutral detergent fiber (NDF) and acid detergent fiber (ADF). But there were not significant differences in nutrient digestibility as the substitution of corn for silage of waste resulting from the extraction of cassava starch intake as well as not interfered in ruminal pH values. It is recommended the replacement of corn for silage 75% of residue of cassava starch extraction.
