Twenty Nelore and twenty F1 cattle (½ Red Angus, ½ Nelore), average age 12 months were compared in pastured raised at southern Bahia, in relation to production characteristics: initial weight (IW), final weight (FW), weight gain, average daily gain (ADG) and total weight gain (WG), infection by endoparasites and heat tolerance (HT). To analyze the effect of genetic group, it was stabilished effects that could influence these characteristics and performed variance analysis using the program SAS. The results showed that IW, FW, ADG and WG of crossbred were statistically different in comparison to zebu cattle. Related to infection by endoparasites and heat tolerance there were no statistical differences between genetic groups.
