Effect of diet with different energy content in growing Murrah buffalo heifers

The relationship between variations of weight and BCS was evaluated using growing buffalo heifers, fed diets with different energy level. 12 Murrah bred heifers (age: 790 days, LW: 400 kg), raised in Saint Paul (Brazil) were equally divided in group H and L fed diets with 5.8 UFL/day and 3.6 UFL/day, respectively. At the end of treatment, groups showed significant differences in weight and values of BCS. In this trial each point of BCS, in Murrah heifers, seems to be equivalent to an increase and/or a loss of about 50 kg of live weight. During this trial the mean value of daily weight gain (DWG) was significantly higher in group H (310 g. vs 0 g.; P
