<b>Performance of Holstein-Gyr crossbred heifers on pasture of <i>Brachiaria decumbens</i> supplemented with multiple supplement or proteined salt

Abstract: ABSTRACT. 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 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 g… Show more

“…Because of concentrate contain 1.5% urea, that led to increasing blood urea without NCG with increasing concentrate intake. Gradual adaptation must be achieved to a non-protein nitrogen and urea supplementation does not exceed 1-2% of total dry matter in the diet [23]. Mahdi [16] referred to increase blood urea when fed 1% urea with 4% concentrate, while GOT and GPT didn't affect.…”
