Boost your artificial insemination success with these tips

By Blake Jackson

Starting an artificial insemination (AI) program can seem overwhelming due to the many steps involved. However, careful preparation and management before, during, and after the program are crucial for its success.

Effective management is just as important as synchronization in ensuring a high pregnancy rate in animals undergoing AI. By making intentional decisions, producers can set their herds or flocks up for success with this reproductive technology.

One of the most impactful management tools is nutritional flushing. According to senior extension educator Melanie Barkley, nutritional flushing involves increasing the animals’ plane of nutrition to enhance their ovulation rate.

This process raises insulin levels, which stimulate the production of the luteinizing hormone (LH). LH triggers the release of oocytes and boosts ovulation rates.

As a result, flushing before AI often leads to higher pregnancy rates in ewes or does since more oocytes are available for fertilization.

However, flushing isn’t effective for animals with a body condition score of 4 or 5. Overconditioned animals respond poorly to flushing, which can decrease the success of laparoscopic AI. Therefore, ensuring animals have an appropriate body condition and nutrient intake is an essential first step in preparing for AI.

Another critical factor is providing proper mineral supplementation. Animals should have access to high-quality mineral mixes tailored to their species several months before AI begins. Adequate mineral intake addresses any deficiencies that could impact reproductive health.

For instance, selenium and vitamin E deficiencies can lower implantation rates, according to the National Animal Disease Information Service (NADIS). Consulting with a veterinarian or extension agent can help identify deficiencies in your area and recommend suitable mineral mixes.

Environmental consistency is also key. Animals need a stress-free, well-organized housing area with access to fresh water and, if necessary, shelter.

Using a handling system, such as a chute or catch pen, can minimize stress during procedures like administering shots or inserting CIDRs. Ideally, animals should remain in the same environment for at least a month before and after AI to avoid stress from relocation.

By planning ahead and focusing on nutrition, supplementation, and environment, producers can significantly improve the success of their AI programs and overall reproductive outcomes.
