Controlled Calving Season Can Boost Cow-Calf Herd Profits

By Blake Jackson

University of Kentucky specialists say establishing a controlled breeding and calving season can significantly improve efficiency and profitability for cow-calf operations.

A shorter breeding window often results in a more uniform calf crop, with calves that are heavier at weaning and more attractive to buyers. In addition, producers can better manage herd health programs and nutritional supplementation when calving occurs within a defined period.

For herds currently operating with year-round breeding, transitioning to a controlled calving season should be approached gradually.

Experts recommend moving to a 75-day calving season over two years rather than attempting the change in a single season, which can create greater production and financial challenges.

The first step is to determine the preferred calving season and its duration. Producers should then evaluate the reproductive status of every cow by reviewing calving records or estimating calf ages if records are unavailable.

This information helps identify breeding patterns and determine whether maintaining one calving season or separating the herd into spring- and fall-calving groups is the best option.

Adequate facilities are also important. A secure bull pen or fenced pasture is needed so bulls can be separated from the herd when required. Producers should remove bulls based on their desired calving schedule and keep them separated until the next planned breeding season.

Approximately 60 days after bull removal, cows should be pregnancy checked. Non-pregnant breeding-age females and open cows with older calves should be considered for culling to improve herd productivity.

Replacement heifers may benefit from beginning their breeding season 20 to 30 days earlier than the main herd. This additional time helps young females rebreed successfully after their first calf, reducing the risk of extended calving seasons in future years.

During the second year, producers should continue the same management approach while shortening the breeding season further to reach the desired calving schedule and improve long-term herd performance.
