Monitor heifer calf progress
Heifer calves should weigh 30% of mature weight at six months old.
This means that by late August, spring-born Holstein Friesian heifer calves need to be at 180kg, and Jersey crossbred-type calves need to be at 160kg.
This is the target for the individual animal, not the average of the group.
Take time to weigh young stock this month. Identify the poorest/slowestgrowing animals in the group and separate them out for extra concentrate feeding, if possible.
Ensure all groups of young stock are fed the highestquality grass possible; heifer calves will readily eat 5kg to 5.5kg DM of high-quality grass per day.
The minimum standard for daily growth rate is 0.7kg liveweight per day (20kg per month), for Friesian and crossbred stock alike.
