Cow-Calf Certification Practice Exam

What is included in a base vaccination program to prevent reproductive disease?

1. A 2-way viral and 2-way lepto vaccine

2. A 5-way viral and 5-way lepto and vibro vaccine

3. A 3-way viral vaccine

4. A killed vaccine only

The correct answer is: A 5-way viral and 5-way lepto and vibro vaccine

A base vaccination program aimed at preventing reproductive diseases in cattle typically includes both viral and bacterial components, which is why the 5-way viral and 5-way lepto and vibrio vaccine is essential. This comprehensive vaccine strategy safeguards against several critical reproductive diseases. The viral aspect of the vaccine usually provides immunity against selected strains of important viruses that can affect the reproductive health of cattle, such as Bovine Viral Diarrhea (BVD) and Infectious Bovine Rhinotracheitis (IBR). On the bacterial front, the leptospirosis vaccine protects against various serovars of Leptospira, which can cause infertility and abortion in cattle. Additionally, the inclusion of vibrio protection addresses vibriosis, a reproductive disease caused by the bacterium Campylobacter fetus, which can also result in adverse reproductive outcomes. In contrast, the other options lack the comprehensive protection offered by a 5-way vaccine. For example, a 2-way viral and lepto vaccine would not cover as many potential threats, while a 3-way viral vaccine offers limited viral protection. A killed vaccine only approach might not provide enough immunity breadth required to ensure overall reproductive health in a herd. Thus, a 5-way combination vaccine is the best
