When is the best calving time?

CattleNetwork:

“Should we go to May and June calving?” That is the question producers are asking themselves. It is a tough question.
A review of data from the CHAPS program through the North Dakota Beef Cattle Improvement Association shows there is not much difference in early March- or early April-born calves and late April-born calving herds.
Calf average daily gain was very similar, no matter when the calves were born. Late April-born calves were lighter due to age and having fewer days to grow before weaning. Overall, reproductive performance also was similar for all calving seasons. From the data available in the CHAPS program, the bottom line is that the only disadvantage for early March calving herds was a slightly longer calving season. The disadvantage for late April calving herds was decreased calf weight at weaning due to the calves being younger.
