Recommendations have varied for the optimal age at first calving in order to maximize milk production and profitability. However, due to variability in bodyweight, there is likely no optimal age at first calving and perhaps we should be focused on optimal bodyweight at first calving instead. Several factors should be considered when determining what optimal means for a dairy farm, listen to today’s podcast to hear about which factors were considered by researchers.
