Two levels of protein and mineral supplements (290 and 400 g.an.-1.day-1) were evaluated and compared with the mineral supplement in 90 Nelore steers on star grass pasture (Cynodon plectostachyus Pilger) during the winter. The supplement intake was ajusted by the concentration of sodium clore into the mixture. Considering the first 28 days (adaptation period) in the statistical analysis, there was no difference in average daily gain (ADG). Taking out this period of adaptation, the ADG was better for the protein […]
