Summary

The nutritional management of weaned heifer calves affects not only the conception rate of yearling heifers but also their subsequent conception rate as 2-year-old cows and the weight of their first weaned calf. The costs involved in raising the replacement heifer and the value of cull heifers, 2-year-old cull cows and weaned first calves all need to be considered when determining the least cost method of raising replacement heifers. 'The effects of raising replacement heifers to prebreeding weights of 50% 62.5% and 70% of expected mature weight are evaluated from an economic perspective. If replacement heifers are only evaluated for one year (1st conception), then raising replacement heifers to only 50% of mature weight is the most economical. However, if the replacement heifer is evaluated through calving, rebreeding and weaning the first calf, then it is most profitable to raise the replacement heifer to 62.5% of expected mature weight.
