dc.descriptionThe objective of this was to determine whether perfomance of beef heifrs of different genetic groups was affected by breed x nutriotional environment interactions. Sixty four weaned heifrs, 16 per genetic group: 1/2 angus + 1/2 Nellore (AN), 1/2 Canchim + 1/2 Nellore (CN), 1/2 Simmental + 1/2 Nellore (SN) and pure Nellore ((NE), were used with or without 3.0KG of concentrate. animal . day in a fertilized coastcross pasture under ratational grazing system. There were effects of genetic group and supplentation (P<0.05) on the weight and age at first estrusbut there was no interaction betweem then. In a rotational grazing sytem wth 4000kg of available dry matter per hectare with 13% of crude protein, the crossbres AN, supplemented or not was more precocious (111 days) than Nellore heifers, showing the firts estrus at 356 days of age and 324kg of live weight.
