How to Get Cattle to Rebreed

Getting cattle to rebreed soon after calving is a necessary function for obtaining full value from a cow. A cow's gestation period is 285 days, which leaves 80 days for rebreeding if she is going to have another calf the following year. The cow's internal reproductive organs require an absolute minimum of 35 days and normally 45 to 50 days to repair themselves after giving birth. A cow will not come into heat during this organ repair period. This leaves 30 to 45 days for her to rebreed. Good cattle management is required for females to rebreed in this short time period.

Instructions

    • 1

      Develop a cattle health plan, with the help of a veterinarian, that keeps your animals healthy and protected against disease. These health plans usually include biosecurity measures, vaccinations, testing, examinations and parasite control. Biosecurity is isolation of livestock from animals outside the ranch that may carry disease.

      Give bulls an annual breeding soundness exam prior to putting them with the cows. This exam shows whether they are still fertile and capable of doing their job. Palpate cows 60 days following conclusion of the breeding season to determine if they are pregnant and their reproductive tract is healthy. Cull cows that are not pregnant.

      Manage your animal nutrition program so that cows have a body condition score of 4 or 5 during the breeding period. Four is a borderline body condition score, but the animal's ribs and hip bones are not showing. At a body condition score of 5, the cow looks slick and there is a small amount of fat on each side of the tail-head. Obtain a beef cattle body condition scoring guide from your nearest animal science college or county agricultural extension agency.

      Provide cows a diet containing 10 percent protein and 65 percent energy when they are with the bulls. These nutrients are obtained from green pasture, good-quality hay, a supplement or a combination of these feeds. The cows, during this period, probably have two-month-old calves and they have just peaked in milk production. Good nutrition is required during this period for them to rebreed.

      Feed a free-choice mineral recommended for your area by the county agricultural extension agent. Regulate mineral intake so each animal gets its required amount. Control intake by adding salt or molasses to the mineral mix.
