To keep herds productive and healthy, here are the most important practices to follow:
1. Health Checks and Vaccinations
Bulls can carry diseases, especially when they come from herds with unknown health histories. To prevent problems, it’s important to:
- Test for Diseases: Before breeding, bulls should be checked for diseases like brucellosis, tuberculosis, trichomoniasis, and bovine viral diarrhea (BVD). Bulls that have been used in other herds are more likely to spread infections such as campylobacteriosis or trichomoniasis. Washing the bull’s sheath with antimicrobial solutions can help reduce risks.
- Vaccinate Regularly: Bulls should be vaccinated for diseases like IBR (infectious bovine rhinotracheitis), BVD, clostridial diseases, leptospirosis, and others. Vaccines should be given at 6 months old, again at 1 year, and then annually—ideally one month before breeding season starts.
2. Breeding Soundness Exam
Every year, bulls should have a breeding soundness exam about a month before breeding season. This gives enough time to address any issues or buy another bull if needed. The exam should include:
- A full physical check of reproductive organs.
- Measuring the size of the scrotum.
- Checking semen under a microscope to assess sperm movement and shape. Advanced tools like computer-assisted semen analysis (CASA) can also be used for more detailed results.
3. Time to Adjust
Bulls should arrive on the farm at least two months before the breeding season to get used to the environment. Any new bulls or cows added to the herd should be kept separate for a while to ensure they adapt well and don’t bring in diseases.
