The objective of this study was to evaluate the divergence of bromatological and fermentative characteristics of silages of 25 sorghum (Sorghum bicolor L. Moench) hybrids. The experimental design was completely randomized with 25 treatments and four replications. The mean values of pH differed with variation from 3.45 to 3.87 for hybrids 866005 and 870051, respectively, and the mean pH value was 3.66. The average percentage of lactic acid ranged from 2.90 to 7.43 dag/kg of dry matter (DM) in hybrids […]

The objective of this trial was to evaluate intake, digestibility, performance, development, feed efficiency and feeding costs in dairy heifers fed increasing levels of citrus pulp that partially replaced Tifton-85 hay (Cynodon dactylon (L.) Pear) in the diet. Twenty-eight Holstein dairy heifers averaging 12 months of age and 184 kg of BW at the beginning of the trial were blocked by initial BW and, within each block (7 blocks), randomly assigned to one of the following four treatments: 0, 16.6, […]
