When you have a pregnant pig, it’s fascinating to observe how her behavior changes. Pregnant sows often display specific signs and tendencies as they prepare for motherhood. Knowing what to expect can help you provide the best care for your expecting pig.
You might notice your pregnant pig becomes more reserved and may isolate herself from the rest of the herd as her due date approaches. This nesting behavior indicates she is finding a safe and comfortable space to give birth.
Additionally, physical changes and increased vocalizations can signal her pregnancy status. Being aware of these behaviors will help you ensure your pig stays healthy and stress-free during her gestation period.
Understanding Pig Pregnancy

When you are caring for a pregnant pig, it’s important to know about her gestation period and the signs of pregnancy. This knowledge helps you provide the best care and support for her and her future piglets.
The Gestation Period
A pig’s gestation lasts about 114 days, roughly three months, three weeks, and three days. During this time, the pregnant pig, or sow, undergoes various changes.
Early in the gestation period, you might not notice significant changes. However, as the due date approaches, her body will show signs of preparing for birthing.
You should monitor the sow’s behavior closely. She may become more vocal or restless. Around weeks three to four, you may notice her appetite increase. As she gets closer to the end of her pregnancy, her nutritional needs will rise even more.
Make sure to provide her with a balanced diet to support her health and the development of the piglets.
Signs of Pregnancy in Pigs
Determining if your pig is pregnant requires observing some clear signs. One noticeable sign is an increase in appetite early on. Once pregnant, she will likely eat more than usual due to the growing piglets.
Another sign to look for is swollen teats. While pigs have round bellies naturally, noticeably swollen teats help indicate pregnancy.
Additionally, watch for behavioral changes. A pregnant sow may become more affectionate or even a bit moody. Keep an eye on her keratinized vulva, too; it may become swollen during pregnancy.
Being attentive to these signs ensures you can provide the right care during this important time.
Caring for a Pregnant Pig

Taking care of a pregnant pig requires attention to her nutritional needs and comfort. Proper care ensures healthy piglets and supports the sow during this important time.
Nutritional Needs and Appetite
A pregnant pig will experience an increase in appetite as her pregnancy progresses. It’s vital to meet her nutritional needs to support the growing piglets.
Feed her a balanced diet rich in proteins, vitamins, and minerals. Consider high-quality pig feeds specifically designed for pregnant sows. Adding fresh fruits and vegetables can also provide essential nutrients.
Keep the feed available at all times, as her appetite may vary. Regularly monitor her weight and adjust her feeding schedule as needed.
Providing clean, fresh water is equally important, especially as she approaches lactation.
Housing and Comfort
Creating a comfortable space for your pregnant pig is essential for her well-being. Ensure her housing is clean, dry, and spacious enough for her to move around.
Provide plenty of bedding, such as straw or hay, for warmth and comfort. As her due date nears, she may exhibit nesting behavior, so give her a quiet area where she can prepare for farrowing.
Regularly check her environment for stressors like loud noises or overcrowding. A calm and safe space will help keep her relaxed and healthy throughout her pregnancy.
The Farrowing Process

Farrowing is an important time for both the mother pig and her piglets. You should be aware of the signs that indicate when farrowing is about to occur, as well as how to manage the farrowing process effectively.
Preparation and Signs of Farrowing
About 10 to 14 days before farrowing, you will notice some signs that your mother pig is getting ready. These include:
- Restlessness: She may seem uneasy or pace around more than usual.
- Nesting Behavior: Your pig might start to create a nest with straw or bedding.
- Physical Changes: Look for swelling in her udder and an increase in the size of her belly.
The day before farrowing, her belly may sag, and the nipples may begin to secrete colostrum. Keep an eye out for any discharge from her vagina, which can indicate the loss of the mucous plug. Recognizing these signs can help you prepare for the arrival of the piglets.
Managing Farrowing and Potential Issues
When the farrowing process begins, stay calm and be prepared to assist if necessary. The first piglet is usually born within 15 minutes of active labor starting. The mother may exhibit mild straining as each piglet is delivered, typically at intervals of about 15 minutes.
Watch out for potential issues such as mummified fetuses. If any piglets appear to be stillborn, they may be mummified, so promptly remove them to keep the area clean. Also, be on the lookout for any signs that the mother needs help.
Your attention during farrowing can make a big difference for the mother pig and her new piglets. Always stay close, but give her space to do what comes naturally.
