What percentage of calves are male?

What is the ratio of male to female cows?

General recommendations for bull:cow ratios: The textbook recommendation for bull:cow ratio is typically 1 bull:20-30 females, with mature bulls closer to the 1:30 ratio and yearling bulls at 1 bull:20 cows. In cows in which estrous synchronization is used, the recommendations are altered by necessity.

How often do beef cattle give birth to twins?

Can a cattleman predict the reproductive value of a heifer?

The cattleman can predict the reproductive value of this heifer calf at birth and save the feed and development costs if he is aware of the high probability of freemartinism. In some cases, there are no symptoms of freemartinism because the male twin may have been aborted at an earlier stage of gestation.
