This work brings to quantify and provide benefits to using this early weaning protocol, showing the benefits for the calf and for females, it is multiparous and / or mostly gilts. Several studies on weaning weight in cattle, which show great variation in the average of this feature. This variation may be the result of genetic variation between arrays, food, reproductive and health management that varies from region to region and from farm to farm, in addition to the different programs of selection and genetic improvement of beef cattle used in the country.

The objective was to evaluate the effects of inclusion of crude glycerin in the diet of zebu heifers in semi-confinement. 22 heifers were used, with an initial average weight of 278.9 kg, divided into two groups: control group (gc) and treated group (gt). The animals were fed a diet with 12% inclusion of crude glycerin to replace concentrate for a period of 81 days, evaluating performance, carcass classification, renal and liver profile and cost effectiveness. The results showed the average weight gain, body condition score, and finish higher for the treated group housing compared to control group. We conclude that the crude glycerin can be used as an energy source in heifers, but without sacrificing performance, as well as the health of the animal termination, but at a lower cost.
