A lot of work and care is required to develop newborn calves into productive, lactating cows. When managed properly, replacement heifers should grow at a rate that allows them to calve at 24 months of age or less. However, a recent report indicated the average age of Holsteins at first calving was 26.9 months, so there are opportunities for improvement. Also, the mortality rate on many farms is higher than desired, reducing the number of potential replacement heifers.
