If there's a history of a certain disease in your herd or area.
However, it is often more practical to give these vaccines at 6 weeks of age with the second dose at 12 weeks of age, negating the need for the third dose. The vaccines that are not effective in the presence of maternal antibody should be given at 6 months of age, with a second dose given 4 to 6 weeks later. Calves should be vaccinated for Blackleg (Clostridium 8- or 9-way), BRD, IBR, PI3, and BRSV. Cows, on the other hand, are vaccinated only if there's a history of a certain disease in your herd or area. IBR-BVD is one vaccine that should be administered to cows no matter where you are or what your herd health history is. Contact your veterinarian for a proper vaccination schedule for your cattle. I know that the younger you are, the more frequently you have to get vaccines. Yearly, in the teen years, boys usually have to get about 1 … more than girls. Every year (pre teen and teen) you have to get about 4 or 5. 5 or 6 for guys. It also depends when you had your last dose of that vaccine. Most calves are vaccinated a few weeks prior to being weaned or at weaning time. Calves should be vaccinated for Blackleg (Clostridium 8- or 9-way), BRD, IBR, PI3, and BRSV. Cows, on the other hand, are vaccinated only if there's a history of a certain disease in your herd or area. IBR-BVD is one vaccine that should be administered to cows no matter where you are or what your herd health history is. Some diseases of cattle for which we use vaccines are: 1. Blackleg2. Brucellosis3. Infectious bovine rhinotracheitis (IBR)4. Bovine virus diarrhea (BVD) By injecting cattle with these vaccines on a yearly basis, you help protect the cattle from getting these diseases for that year. For rabies, in most states it is also 3 years but you … would need to check with your local and state laws as some states require every year. Beware of over vaccination. Most pets do not need to be revaccinated even every 3 years. Well we don't have kids, but believe me, the livestock vaccine guilt is just as bad (for me anyway). For cattle there are two main vaccinations, 5-in-1 and 7-in-1 (more here). The first vaccinates against 5 different Clostridium bacteria that cause a range of diseases in cattle.
