DETERMINATION OF ANIMAL LOAD AND GRAZING SYSTEM IN THE WEIGHT GAIN OF BOVINES WITH SECONDARY VEGETATION FEEDING

The present study was to evaluate the weight gain of bovinesin three animal loads with two grazing systems and levels grazing, furthermore botanic composition secondary vegetation areas. carried out during years, in first year, used were 0.25, 0.50 0.75 unit per hectare (AU/ha).The which animals evaluated 8 years old. Botanic determined by transects at beginning experiment. rotational alternate each load system.The initial average weights 175 kg evaluation 56 days. experimental design random totally factorial arrange 3X2, factor second system. Results indicated changes caused effect (P≤0.05), furthermore, system showed significative statistical differences between treatments interaction. best 520 g day detected 0.50AU/ha (P≤0.05).
