Milk yield in Nellore cows and suckling behavior of their calves of different production systems: NR- Extensive Nellore, NI- Intensive Nellore; and three crossbreeding systems (CN- Canchim-Nellore, AN-Angus-Nellore and SN-Simmental-Nellore in intensive management), were studied. Milk production of cows and number and length of suckles, and daily gain (kg/day) of calves were obtained in three moments of lactation (60, 120 and 180 days after calving). Moment of lactation and production system by lactation moment interaction had a significant effect in […]
