Research demonstrates estrous synchronization in cows can improve calving distribution and progeny value.

Synchronizing estrous is a tool that can be used to concentrate when animals exhibit estrus and potentially calving distribution.

Calving records collected between 2000 and 2008 at the Gudmundsen Sandhills Laboratory near Whitman were used to determine the effect of estrous synchronization on calving distribution and the impact of time of calving on steer weaning, feedlot and carcass characteristics.

A major goal in estrous synchronization is to increase the percentage of calves born early in the calving season. University of Nebraska-Lincoln research found that calves born in the first 21 days of the calving season are heavier and more uniform at weaning and have greater carcass weights and quality grades.
