How age at first calving influences productivity and fertility

As accelerating age at first calving could result in lower rearing costs, the strategy sounds a valuable tool for sustainable dairy farming, however, the impact of a reduction in age on long-term performance remains unclear to substantiate the strategy. In this recent study, researchers from Kitasato University in Japan evaluated how age at first calving impacts milk productivity and reproductive performance up to the third lactation. Reports show that most previous studies have focused on he
