Pre-breeding (open heifers) |
- Open heifers are worked through the chute 1 to 3 months before breeding for physical exams to evaluate body condition, udder, feet, teeth and eyes. A veterinarian can use Breeding Soundness Evaluation (BSE) procedures to determine reproductive tract scores and pelvic measurements. Animals that are in poor condition or not suitable for reproduction are culled. Retained animals are given annual, routine vaccines and treated for worms and flies if necessary. Their nutrition is adjusted if their condition warrants.

Pre-breeding (bulls) |
- Bulls are worked through the chute 1 to 3 months before breeding for physical exams to evaluate body condition, prepuce, feet, teeth, eyes and nose. A veterinarian can use Breeding Soundness Evaluation (BSE) procedures to examine accessory sex glands, penis and testicles, and to do microscopic examinations of the semen from electroejaculation.
- This helps in classifying bulls’ breeding potential. Animals that are in poor condition or are not suitable for reproduction are culled. Retained animals are given annual, routine vaccines and treated for worms and flies if necessary. Their nutrition is adjusted if their condition warrants.

Breeding (bulls) |
- Bulls are turned in to the herd at an optimal bull-to-cow ratio for the stocking rate. Bulls need to be observed to be sure they are adequately working the cows and heifers and properly serving and mating those in estrus. Bulls should be observed periodically to check for injury to the sheath, penis, testicles, feet or legs that could hinder their ability to breed.
