Descripción

Research to evaluate the finishing of heifers in feedlot is still little explored in Brazil. The objective of this study was to evaluate the productive and economic performance of crossbred beef heifers in feedlot finishing fed different sources of non-protein nitrogen (NNP). 552 crossbred beef heifers were used (292 ½ Angus ½ Nellore (A×N) and 260 ½ Charolês ½ Nellore (C×N)), with a mean initial weight of 374.23 ± 55 kg and an age of 24.0 months ± 2 months, distributed in a completely randomized design. The diets evaluated had the same levels of protein and energy, but different sources of NPN.
