Cattle producers commonly evaluate reproductive performance by determining how many cows became pregnant during the breeding season. Although pregnancy rates are important, when the females become pregnant within the breeding season is a major component of cow-calf profitability. Cows that become pregnant early in the breeding season calve earlier in the calving season. Consequently, they have more time to recover before the next breeding season, which increases their chances of becoming pregnant and staying longer in the herd. Estrus synchronization programs have the ability of inducing estrus and can be combined with natural service to increase the percentage of cows and heifers that become pregnant early in the season. This publication describe different synchronization protocols that can be incorporated by cow-calf producers utilizing only natural service.
