The objective was to evaluate the effect of genetic group (GG) and non-protein nitrogen (NPN) sources added to the total ration on the carcass and meat characteristics of cull heifers finished in confinement. The meat used was from 40 females, 20 ½Angus½ Nellore (A×N) and 20 ½ Charolais ½ Nellore (C×N), with an average initial weight of374.23 ± 55 kg and age of 24.0 ± 2 months. The diets evaluated had the same protein and energy levels, but different sources of NPN.openAccessCarcaçaNovilho de CorteRaçaBeef carcassesHeifersFatty acidsMeatMixed breedsUreaCarcass and meat characteristics of mixed-breed cull heifers fed diets with different sources of non-protein nitrogen in feedlots.Resumo em anais e proceedings
