Are 60 Percent Calving in First 21 Days?
If the percentage of cows calving the first 21 days of the calving season is less than 60 percent and the percentage of cows calving the second 21 days of the calving season is greater than 25 percent, a serious re-evaluation of the herd needs to occur.
Just do it: Grab a pen and paper to calculate the percentage of cows calving in the first 21 days of the calving season. This is a very important number to record and think about as one develops management plans and reviews those plans.
Why? The upcoming breeding season is not very far away. For those who have an early calving season, the bulls already may be out with the cows.
