The aim of this experiment was to compare the efficiency of a hormonal protocol, associated to the temporary weaning for 96 hours, with the definitive weaning at 60 days in beef cows, for the induction of estrus and ovulation. One hundred and eighty-three suckled beef cows were used. The breeds of the cows were Charolais (C) and Nellore (N) and their crosses. The animals were genotyped as homozygous (HOM) and heterozigous (HET) for the microsatellite BMS3004, that is localized in […]
