The use of different types of concentrated supplements on the performance of Nellore calves grazing Urochloa brizantha cv. Marandu in the dry season was evaluated. The experiment was conducted on 24 ha divided into 12 paddocks. Seventy-two calves with initial body weight (BW) 176±14kg for 140 days of experiment were used. Evaluated treatments included: Mineral, Salt+urea (mineral with 30% urea), Protein (supplementation with 45% crude protein (CP) and 46% total digestible nutrients (TDN)); and Protein+energy (with 28% CP and 73% TDN). The Mineral, Salt+urea, and Protein were offered ad libitum, and the Protein+energy 5g/kg BW. Protein+energy showed the highest (P< 0.05) intake (3.66g/kg BW) followed by the Protein (1.61), Salt+urea (0.36), and Mineral (0.32). The two latter supplements were not significantly different (P> 0.05). The highest (P< 0.05) average daily gain (ADG, kg/day) was observed in the Protein+energy (0.074). Average daily gains for the Protein and Salt+urea (0.014 and -0.024, respectively) were not significantly different (P> 0.05), but were significantly higher (P< 0.05) than the Mineral (-0.085). Therefore, during the dry season, to prevent the loss of bovine weight the supplements must supply in addition to minerals, also energy, non-protein nitrogen (NNP), and true protein.
