REPLACEMENT OF GROUND CORN GRAIN BY SOYBEAN HULLS ON THE PERFORMANCE OF CONFINED BEEF CATTLE HEIFERS
Abstract
This trial was conducted to determine the value of soybean hulls as a replacement for com grain in finishing beef heifers diets. Dietary treatments consisted of four substitution levels (0, 25, 50 and 75 %) of com grain by whole soybean hulls. Hundred and eight beef caule heifers were used in a randomized complete block design, with four treatments, three replications, with nine animais in each pen. Animais were fed twice a day with a com silage based diet, plus whole soybeans, mineral supplement and a variable amount of ground com grain and soybean hulls. No differences were detected among levels of soybean hulls substituting com grain upon final weight, daily weight gain or feed conversion.
