Common Mistakes During Artificial Insemination and How to Avoid Them (continuous study)

Even experienced farmers can make small errors that reduce insemination success rates.
Understanding and preventing these mistakes is key to improving results.
1. Poor Hygiene
Failing to clean the vulva before inserting the catheter can introduce bacteria, causing infections
and reduced fertility. Always sanitize hands and equipment.
2. Incorrect Catheter Insertion
Inserting the catheter too shallow or too deep can lead to back flow of semen or damage. Ensure it
locks gently at the cervix before introducing the inner rod.
3. Mishandling Semen
Semen must be stored at the correct temperature (17–18°C) and gently mixed before use. Avoid exposing it to sunlight or shaking it roughly.
4. Wrong Timing
Inseminating too early or too late in the heat cycle greatly affects conception rates. Always perform
the process within 10–15 minutes after heat confirmation.
5. Lack of Records
Failing to track insemination data makes it hard to evaluate success and schedule second
insemination. Recording information helps in herd management and fertility analysis.

Best Practices for Detecting Sows in Heat Before Insemination (Continuous study)

Accurate heat detection is the foundation of successful artificial insemination. Missing the correct
timing can lead to failed fertilization, wasted semen, and economic loss.
1. Use a Teaser Boar
Expose the sows to a mature, active boar. The boar’s presence helps stimulate and identify those
ready for insemination.
2. Observe Physical Signs
Look for a red, swollen vulva, mucus discharge, and restlessness. These signs appear just before
and during estrus.
3. Perform the Standing Reflex Test
Apply gentle pressure on the sow’s back. If she stands still and raises her ears, she’s in standing
heat — the ideal time for insemination.
4. Timing
Inseminate the sow about 10–15 minutes after removing the teaser boar, allowing her to calm down
while maintaining peak receptivity.
5. Record Observations
Always document the date, time, and behavior of each sow to ensure precise insemination
scheduling and better reproductive tracking.

Advantages of Post-Cervical Artificial Insemination (PCAI) in Pig Production (Continuous study)

Post-Cervical Artificial Insemination (PCAI) is a modern technique that delivers semen deeper into
the sow’s reproductive tract than traditional AI. It offers numerous benefits for commercial and
small-scale farmers alike.
1. Reduced Semen Use
PCAI allows the use of smaller semen volumes per sow (often 50% less than traditional AI) without
reducing fertility. This helps farmers inseminate more sows from a single boar’s collection.
2. Improved Fertility and Conception Rates
By depositing semen beyond the cervix, PCAI ensures sperm cells reach the uterus more
effectively, resulting in higher conception rates and larger litters.
3. Better Genetic Progress
Using PCAI, farmers can access top-quality semen from superior boars, improving the herd’s
overall genetics and productivity over time.
4. Labor Efficiency

The PCAI procedure is faster and requires less handling time per sow. With proper training,
technicians can inseminate more animals in a shorter period.
5. Animal Welfare
This method is gentle and minimizes discomfort when performed correctly, improving sow welfare
and handling experience.

Understanding the Artificial Insemination Process in Pigs (Continuous study)

Artificial Insemination (AI) is one of the most effective and modern techniques used to improve pig
breeding performance. It allows farmers to use high-quality boar semen efficiently and ensure
better genetic progress across their herds. The image above demonstrates the step-by-step
process of inseminating sows using a method called Post-Cervical Artificial Insemination (PCAI).
Step 1: Detecting Heat
Start by bringing a mature boar near the group of sows. Observe for signs of heat such as
restlessness, mounting behavior, swollen vulva, and standing reflex. Only sows that show strong
standing reflexes should be inseminated.
Step 2: Preparing the Sow
Once the sow is identified in heat, remove the boar and wait for about 10–15 minutes. During this
period, the sow relaxes, allowing smooth insemination. Clean the vulva thoroughly to prevent
contamination.
Step 3: Inserting the Catheter
Gently position the catheter and lock it into the cervix. For PCAI, insert the inner rod through the
catheter to pass semen beyond the cervix, directly into the uterus.
Step 4: Connecting the Semen Bag
Before use, gently agitate the GTB (semen) bag to homogenize the dose. Then connect the bag to
the inner rod tip and allow the semen to flow slowly.
Step 5: Completion
Once insemination is complete, remove the catheter with a quick motion. Record the insemination
details for each sow. A second insemination can be done 20–24 hours later for better fertility
results.

VAF Hosts Refresher Training on Swine Artificial Insemination for Rwandan Veterinarians

During the days from the 14th to 15th May 2025. At VAF, we organized a refresher training for the veterinary in the Rwanda Council for Veterinary Doctors (RCVD) with a Holland expert Dr. Jan Merks. The trainings were basically focusing on the Artificial insemination process. The attendees were able to learn all the steps involved in the modern artificial insemination from the theoretical knowledge about semen and swine genetics all the way to the final step of swine insemination together with heat detection in sows.

On the first day, the attendees first of all were taught about the technology of genetic study and cross breeding in swine. In this context, the attendees were taught about different pig breeds with their history, the history and evolution of Artificial insemination in swine. The trainees were also given a detailed contrast between the natural mating and Artificial insemination. This allowed us and the team of trainees to have a common sense about both methods.

They were also taught about the evolution of different breeds evolution based on their origin location like the breeds from Europe, Asia and in the Americas. Thanks to the Expert, Dr. Jan Merk for his knowledge in swine genetics and Artificial insemination. After the genetics in swine, the trainees were also taught about the most popular breeds in Rwanda, with details about the adaptation of each, the positive and negative sides for each.

 

The trainees were also taught also about the boar’s behavior and also the sow behavior during semen collection and also heat detection in the sow. In heat detection, the trainees were taught about mostly the standing heat and the determination of the heat in swine. They were also taught about the modern and efficient way of insemination like the insertion of the AI catheter. About the semen collection the trainees were taught how to examine the semen collected for motility, the density and also the formular for adding extender to the collected semen and finally to the step of putting the collected semen into the coolant and to the step of semen distribution and insemination.

 

On the second day, the 15th May, it was the day of practicing what the trainees have been learning for the first day. The trainees arrived at the VAF headquarters because all they were going to see was mostly practical. They were firstly taken back through what they saw the day before just to keep the refreshed for the practical part. Starting the practical part, the trainees were taken for the farm tour observing and learning more about the breeds and also observing different sows to look for some sows or gilts that are in heat. That was one of the tasks they were given before the farm tour just to keep them in the mood of what they have been through in the theoretical part the day before.

The tour around the farm was leading them to the VAF laboratory that also conjuncts with the semen collection point. Arriving at the semen collection point the trainees were taught visually how semen is collected, tested (for color, smell, motility, density) and stored. That marked the end of the trainings and the trainees were evaluated about the knowledge they have been given during the two days.

The Role of Boars in Heat Detection and AI Success

Boars play a critical role in heat detection and maximizing conception rates in artificial insemination programs. Understanding how to use boars effectively can improve reproductive efficiency.

How Boars Stimulate Estrus Expression

  • Pheromone Release – Boars produce pheromones that trigger estrus behaviors in females.
  • Physical Stimulation – Nose-to-nose contact with a boar encourages standing heat in sows.
  • Boar Presence & Movement – Keeping a boar near females helps identify those entering heat earlier.

Best Practices for Boar Use in AI Programs

  • Daily heat detection with a boar – Helps pinpoint standing heat more accurately.
  • Rotate boars – Different boars stimulate estrus differently.
  • Use trained boars – A well-trained boar is more effective in detecting estrus than a young, inexperienced one.

🐖 Did You Know? Studies show that boars can improve estrus detection accuracy by up to 30% when used correctly.
