Abstract

The aim was to verify the association level between the steers performance of Nellore breed evaluate in weight gain test on pasture with the DEP 450 days and total genetic merit of theirs fathers. The data used in this study was from Nellore animal, in pure blood, form Camargo farm, located in the Araguapaz city, Goiás state. The test showed duration of 294 days, being 70 days of adaptation and 224 days of test. All of animals were evaluated in the same conditions of handling and alimentation.  There was average increase of 107 Kg from initial to final weight, showing daily average gain of 0.36 kg/day. Can be detected that the superior category showed the highest percentage of classified animals (40.91%).  There was increase in the simple correlation estimative of DEP 450 days of bulls with initial weight (0.12) and final weight (0.35) of their offspring. The positive association between the weight performance of offspring with DEP 450 days and total genetic merit of bulls shows that these tools are necessary for the bulls’ selection
