Advice for dairy farmers: Late calvers are often neglected part of the herd

According to Irish Cattle Breeding Federation (ICBF), the average calving interval on Irish farms is around 400 days. The ideal target is 365 days.

The median calving date is March 10, but the optimum target for most farmers is February 20.

The average six-week calving rate is 55%; the ideal target is 80-90%, which only a minority of farmers achieve.
