Final Answer:
Stallions can become permanent carriers of this disease; therefore, colts intended to be used as breeding stallions should be vaccinated for:d) Contagious Equine Metritis
Step-by-step explanation:
Colts intended to be used as breeding stallions should be vaccinated for d)Contagious Equine Metritis (CEM), making option d the correct choice. CEM is a highly contagious bacterial infection that can lead to persistent carriers among stallions. Vaccination is a crucial preventive measure to control the spread of CEM and protect the reproductive health of horses, especially those intended for breeding purposes.
Contagious Equine Metritis is caused by the bacterium Taylorella equigenitalis, and its impact on fertility can be significant. Stallions infected with CEM may become persistent carriers, serving as a source of infection for mares during breeding.
Vaccination helps reduce the risk of CEM transmission, protecting the overall reproductive health of the horse population. The implementation of vaccination protocols is a standard practice in equine breeding programs to ensure the well-being and reproductive success of stallions.
Understanding the specific vaccination needs for different diseases is essential in equine healthcare. In the context of breeding stallions, prioritizing vaccination against Contagious Equine Metritis aligns with industry best practices and contributes to maintaining a healthy and disease-free equine breeding population.
