Abstract
This study examined the ability of estrous synchronization prior to natural breeding in beef cows to help producers improve the performance and profitability of their herd. To do this, we compared published literature on three different breeding strategies: 1) cows were bred by natural service without use of estrous synchronization, 2) cows were bred by natural service following the use of estrous synchronization and 3) cows were bred using timed artificial insemination with estrous synchronization, followed by the use of clean up sires. Bull carrying capacity, veterinary costs, labor, and calving distribution were determined for each strategy. Costs and revenue analysis were conducted for each strategy to examine economic efficiency within the herd. While there were increased costs associated with handling, labor, and product, improved revenue can be realized by increasing the number of calves born during the first 21 days of the calving season due to heavier weaning weights and decreased labor.
