However, an alternative to this problem is the use of adapted taurine breeds zebu breeds in crossbred systems. For this reason, the objective was to evaluate the influence of paternal breed on the performance of crossbred cattle. Two hundred eight animals (male and female), produced from mating Caracu, Senepol and Guzerá bulls with Nellore, ½ Nellore + ½ Angus and ½ Nellore + ½ Caracu cows were used. The animals were raised in pastures of Brachiaria brizantha cv. Marandu receiving mineral supplements during the cow-calf phase, and receiving protein and protein-energy supplementation during the growing phase  aBeef cattle  aHeterosis  aZebu  aAdapted taurine  aProduction systems1 aARAÚJO, T.
