Abstract

This experiment evaluated the effects of treatments simulating pregnancy (100 lead spheres in the uterus - LEA) and implanted growth promoter (GPR), compared to a control group (EMP) on feed intake behavior, rumination behavior, and water immersion behavior. Twenty Murrah buffaloes were used. After 84-day confinement, the heifers’ behavior was observed for five days. The feeding time was longer in GPR (1352.5min.) than in EMP (1120.2min.) and LEA (1128.1min.); the last two groups did not differ from each other. The rumination time was longer in GPR (2598.5min.) than in LEA (2169.7min.), and EMP had an intermediary time (2357.4min.). As for water immersion, the time was similar for EMP (1369.3min.) and LEA (1289.9min.) and longer in GPR (604.0min.). Implant utilization influenced feeding and rumination times
