How to Care for Pregnant Sows and Ensure Healthy Litters

Aaron Vet Farms – Expert Pig Farming Advice for Better Productivity

Proper sow care during pregnancy (gestation) is one of the most important factors in achieving high productivity in pig farming. A well-managed gestating sow produces healthier piglets, reduces farrowing complications, and ensures stronger litters with higher survival rates. At Aaron Vet Farms, we guide farmers through the best practices to guarantee excellent reproduction performance and maximum farm profitability.

Why Good Care for Pregnant Sows Is Important

Pregnant sows require special attention because:
They carry developing embryos for 114 days (3 months, 3 weeks, 3 days).
Their nutritional needs change gradually during gestation.
Poor management can lead to low litter sizes, stillbirths, weak piglets, or farrowing complications.
Proper care leads to healthy litters, faster growth rates, and better sow longevity.

1. Proper Nutrition for Pregnant Sows

Feed High-Quality Sow Gestation Diet
A balanced gestation ration ensures proper fetal development and maintains the sow in good body condition. Important nutrients include:
Energy for growth and maintenance
Protein for fetal development
Vitamins and minerals like calcium, phosphorus, selenium, and folic acid
Fiber to aid digestion and prevent constipation
A typical pregnant sow requires 2.2–2.5 kg of quality gestation feed per day, depending on her body weight and farm system.
Avoid Overfeeding and Underfeeding
Both extremes are harmful:
Overweight sows may experience difficult farrowing and produce weak piglets.
Underweight sows produce small litters and lose weight during lactation.
Maintain the sow at a Body Condition Score (BCS) of 3 throughout pregnancy.
Provide Fresh Clean Water
Pregnant sows must have access to 10–20 liters of clean water daily. Dehydration affects feed intake, fetal growth, and milk production later.

2. Housing and Comfort for Pregnant Sows

Provide Enough Space
Whether you use individual stalls or group housing, enough space reduces stress.
Stress in pregnant sows can lead to:
Abortion
Aggression and injurie
Poor fetal development
Maintain Clean and Dry Bedding
Good bedding such as straw, wood shavings, or rice husks keeps the sow warm, comfortable, and reduces infections.
Control Temperature and Ventilation
Pregnant sows cannot tolerate heat stress. Maintain temperatures between 18°C–22°C.

Ensure proper ventilation to remove:

Heat
Ammonia
Dust
Moisture

3. Health Management During Gestation

Regular Deworming
Deworm sows at the beginning of gestation and again two weeks before farrowing to reduce parasite load and improve immunity in piglets.

Vaccination Program

Maintain an updated vaccination schedule depending on local veterinary guidelines. Essential vaccines include:

Parvovirus (PPV)

Erysipelas

Leptospirosis

Colibacillosis (E. coli)

Vaccinate 2–4 weeks before farrowing to improve colostrum immunity in piglets.

Monitor Sow Body Condition

Conduct body condition scoring (BCS) every 30 days.

A healthy gestating sow should have:

Firm ribs (not visible)

Adequate muscle and fat cover

No signs of rapid weight gain or loss

Reduce Stress

Stress triggers hormones that can cause early abortions.

Avoid:

Loud noises

Rough handling

Frequent movement

Mixing sows aggressively

Handle pregnant sows calmly and gently.

4. Preparing the Sow for Farrowing

Move the Sow to the Farrowing Crate on Time
Transfer her to a clean, disinfected farrowing crate 7–10 days before expected farrowing date.

This allows her to:

Adjust to new surroundings
Reduce farrowing stress
Build immunity through exposure to the environment
Form a bond with the crate
Prepare a Clean Farrowing Area
A clean environment prevents infections like mastitis and piglet diarrhea.
Ensure:
Washed and disinfected crate
Fresh bedding
Good drainage and ventilation
Heat lamps or warm creep area for piglets (32°C at birth)
Increase Feed Slightly in Final Weeks
Energy needs rise in the last 3 weeks. Increase feed by 0.5 kg/day, but avoid overfeeding.

Watch for Signs of Approaching Farrowing

A sow close to farrowing will show:
Nesting behavior
Swollen udder
Milk letdown (can be tested by gentle pressing
Restlessness
Reduced appetite

5. Assisting the Sow During Farrowing

Most sows farrow smoothly without help, but monitoring is essential.

What to Do During Farrowing

Keep the farrowing area calm.
Be present to monitor progress.
Remove membranes from piglets’ noses to help breathing.
Dry piglets using clean towels.
Ensure the piglets suckle colostrum immediately within 1 hour of birth.

When to Call a Veterinarian

Seek assistance if:
Labor lasts more than 1 hour without producing a piglet.
The sow appears exhausted.
You suspect a piglet is stuck.
There is excessive bleeding.

6. Post-Farrowing Sow Care

After delivery:
Provide Fresh Water and Energy Source
Use warm water mixed with glucose or molasses to restore energy.
Offer Feed Gradually
Start with a small amount of easily digestible feed, then increase gradually over 5 days.

Check for Common Problems

Watch for:
Mastitis
Metritis
Loss of appetite
Fever
Agalactia (failure to produce milk)
Early treatment ensures quick recovery.

Conclusion

Caring for pregnant sows properly is essential for producing strong, healthy litters and maintaining high farm profitability. With the right nutrition, comfortable housing, health management, and proper preparation for farrowing, farmers can significantly improve reproductive performance.
