摘要

This retrospective study of records from a dairy farm explored the impact of receiving a second feeding of colostrum 5–6 h after an initial meal of 3 L of quality-tested colostrum on calf health and productivity until the first lactation. Calves that received a second feeding were less likely to develop failure of transfer of passive immunity or morbidity pre-weaning than calves only receiving one feeding. Similarly, calves receiving a second feeding showed a greater growth rate until weaning and tended to produce more milk in the first lactation. However, receiving a second feeding was not associated with differences in pre-weaning mortality or reproductive efficiency. Our results show that feeding calves a second meal of colostrum within the first few hours of life has a positive impact on calf health and might have positive effects into the first lactation.
