Sexually Transmitted Diseases of Bulls

Area of Science:

• Animal Science
• Veterinary Medicine
• Reproductive Biology

Background:

• Reproductive efficiency is paramount for economic success in beef and dairy cattle production.
• Achieving optimal reproductive performance involves early conception, sustained pregnancy, and successful calving and rebreeding cycles.
• Disruptions in the reproductive cycle lead to significant production losses in both cow-calf and dairy herds.

Purpose of the Study:

• To highlight the critical role of efficient reproduction in cattle production systems.
• To outline the key components of successful reproduction in beef and dairy cows/heifers.
• To underscore the economic implications of reproductive performance and potential risks associated with breeding bulls.

Main Methods:

• Literature review on reproductive physiology and management in cattle.
• Analysis of economic impacts of reproductive traits in cow-calf and dairy sectors.
• Identification of critical success factors for cattle reproduction.

Main Results:

• Early conception, unassisted calving, and timely rebreeding are essential for annual calf production in cow-calf herds.
• Consistent calving every 12-15 months is necessary for sustained milk production in dairy cattle.
• While fertile bulls are necessary, they pose a risk for disease transmission during breeding.

Conclusions:

• Efficient reproduction is the most significant economic driver in cow-calf production.
• Maintaining reproductive cycles is vital to prevent production delays and economic losses in dairy cattle.
• Managing disease transmission risks from bulls is an important consideration for overall herd reproductive health.
