This guide discusses the benefits of maintaining the optimum calving interval and offers suggestions for accomplishing this reproductive management technique.
Most dairy producers are aware that an optimum calving interval is 365 days. This is a normal lactation length of 305 days with a dry period of 60 days. This interval is often looked at as a goal to strive toward rather than a goal that must be reached to maximize income from the sale of milk.
