| Popis: | Performance of Steers Supplemented in Pasture with Protein-energy Mineral Salt in dry season. The research was carried out to evaluate the protein-energy effect of multiple supplements on animal production, N urea in plasmatic quantities and economic parameter of growing beef cattle in pasture during dry season. Thirty-two castrated beef cattle steers were divided into four groups of eight animals. They were analyzed according to a randomized block design at 5% of significance. Each group received one treatment to pasture with addition of mineral salt + urea + corn; mineral salt + urea + soybean meal; mineral salt + urea + corn + soybean meal. There was no difference (P>0.05) between supplements for daily LWG and for average metabolic weight. This can be justified by forage quality combined with availability of DM/ha. As for the variable N-urea in the blood, results indicated higher protein value as an effect of the 50 % addition of soybean meal in the treatment composition. The supplementation of animals in pasture with multiple supplements and low consumption allowed LWG benefits. Its use depends on the cost of the supplement and the price of the meat. |
