This work was conducted aiming to evaluate the effect of different forage levels in the diet on the average daily dry matter intake (DMI), average weight gain (AWG), feed:gain ratio and carcass yield. Thirty-six pure Holstein bull calves, 60 days old with initial average live weight (LW) of 78 kg, were allotted in a completely randomized experimental design. The animals were ad libitum fed with diets contained 10, 25, 40, and 55% of forage, on the DM basis, using chopped […]
