ABSTRACT – The effect of the combination of energy sources (corn or cassava hull) and protein sources (cottonseed meal or yeast + meat and bone meal) in four diets, using corn silage as forage source, on the performance and intake of DM, CP, OM, ME, ADF, NDF, starch, Ca and P, using heifers. The effect of the addition salt or mineralized salt was also evaluated. A total of 28 heifers with average 303 kg LW and 18 months of age, […]

ABSTRACT – Twenty-eight heifers, with average 303 kg LW were used to determine the apparent digestibility of dry matter (DM), crude protein (CP), organic matter (OM), gross energy (GE), acid detergent fiber (ADF), neutral detergent fiber (NDF) and starch in diets containing corn or cassava hull and yeast or cottonseed meal plus meat and bone meal, during seven days. The addition effect of salt or mineralized salt to the diets was also evaluated. The acid insoluble ash was used as […]
