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.
