Forty-eight crossbreed beef cattle were used to evaluate four commercial mineral supplements: Treatment A- Salt + protein without urea (20% crude protein); B – salt + protein with urea (52,5 % crude protein), C) mineralized salt; D) mineralized salt with urea (91% crude protein). The animals were distributed into 24 plots of Braquiaria decubens grass, with supplementation of (10.5 kg/an/day) of sugar cane, during 112 days, with 28 days of adaptation and 84 days of data collection. The animals were […]
