Management Coming Soon: Breeding Season By Taylor Grussing, SDSU Extension Cow/Calf Field Specialist With calving season nearly wrapped up and pairs being turned out to green grass, breeding season will begin before long. In order to maintain a 365 day calving interval, cows need to be rebred within 80 days after calving. Cows that calved at the beginning of the calving season, should have resumed estrous cycles around day 50 postpartum, as observed by showing mounting behavior and mucus discharge from the 164 | JUNE/JULY 2018 vulva. These cows are prime candidates to breed again early in this coming breeding season. The later calving cows may not be showing signs of estrus yet, but once uterine involution is complete, they will be ready for breeding season too. The earlier we can get cows bred in the breeding season, the greater their lifetime productivity will be due to less open cow days and also raising older and heavier calves to weaning. Plan the Breeding Season Before starting the breeding season, make sure you have a plan in place for what type of breeding program you want to utilize and what supplies are needed for either artificial insemination or natural service. For example, utilizing artificial insemination and estrus synchronization provide many benefits to beef producers
