Performance of Holstein-Gyr crossbred heifers on pasture of Brachiaria decumbens supplemented with multiple supplement or proteined salt Animal Sciences
Santos, Ronald Matos dos; Lana, Rogério de Paula; Teixeira, César Roberto Viana.
 This study aimed to evaluate the performance, efficiency and economic viability of different supplements for dairy heifers on Brachiaria decumbens pasture. Twelve heifers with 186 ± 30.5 kg average weight were divided in three groups of four animals. The treatments were mineral salt ad libitum; 0.4 kg animal-1 day-1 proteined salt and 1.0 kg animal-1 day-1 multiple supplement. The experimental design was randomized blocks, with the contrasts considered significant at 5% probability. There was greater (p < 0.05) body weight and higher daily weight gain in animals supplemented with proteined salt or multiple supplement, compared to supplemented with mineral salt. There was no difference (p > 0.05) in any of the performance parameters between proteined...
