Reproductive Health for Livestock 

For many farms, effective reproduction is crucial for success. Keeping your animals healthy and able to reproduce increases productivity and improves the herd’s overall health. Good reproduction management results in higher birth rates, healthier young animals, and a more efficient herd. Open livestock, which are females that are not pregnant, are common on farms. While reaching a 100% pregnancy rate isn’t realistic, it’s important to review your management practices, nutrition, and herd health if you have more open animals than usual or if the rate is over about 5% in larger herds. 

The role of nutrition  

Good nutrition is essential for successful reproduction. Drought, natural disasters, and high feed costs can lead producers to use questionable feeds in tough times. Feeds that have mycotoxins, like aflatoxin, can cause abortions. If you’re worried about your feeds, testing them can help determine if mycotoxins are present. You may need to stop using a risky feed or add a toxin binder.  

Water can also become contaminated, especially if it has too many minerals, depending on its source. Regularly check the Body Condition Score (BCS) of your livestock to monitor the health of breeding animals. Both underweight and overweight animals can face reproductive problems. If you are dealing with these issues, it’s crucial to test and consider all possible causes. 

Effective breeding management  

Managing breeding effectively is essential for a productive herd. Start by choosing breeding animals that have strong reproductive traits and good fertility. Pay attention to the Expected Progeny Differences (EPDs) for the livestock you know about to ensure they match your breeding goals. Selecting specific genetics can enhance the overall reproductive performance of your herd over time. It’s also essential to understand the estrous cycle of your livestock. This helps you breed them during their peak fertility period, or estrus, which increases the chances of successful conception.  

If you are using artificial insemination (AI), you can specifically choose the males you are breeding your females to, allowing you to increase progress toward your genetic goals. When using AI, it is vital to understand how to detect estrus to determine best when to breed your livestock. Correct semen handling and having an experienced inseminator will increase your chances of getting successful pregnancies.   

Disease prevention and health monitoring  

Reproductive health is essential for the overall health of animals. Diseases can affect fertility and the success of pregnancies. Vaccination programs can help prevent reproductive diseases like brucellosis, leptospirosis, and bovine viral diarrhea (BVD). Work with your veterinarian to create a vaccination schedule for your herd. Regular health checks for the herd help you find and deal with potential reproductive problems early. Use biosecurity measures, such as isolating new animals, limiting visitors, and keeping livestock equipment clean, to lower the risk of bringing harmful diseases into your herd. 

To keep livestock healthy and productive, you need a well-rounded approach. This includes good nutrition, effective breeding management, and careful monitoring. Keeping accurate records is important. It helps you track breeding dates, sires, pregnancy checks, and reproductive performance, making herd management easier. You can improve your herd’s reproductive performance by following the best practices you and your veterinarian establish. Investing in reproductive health benefits your livestock and supports your farm’s long-term sustainability and profitability.
