CATDOLL : How does a sow determine whether it is pregnant? Learn these tips to easily deal with sow breeding problems

Observing the sow’s behavior

After a sow becomes pregnant, it will show a series of behavioral changes, such as increased appetite and a plump body. A non-pregnant sow may appear anxious, restless or have a decreased appetite. These subtle behavioral changes can allow breeders to initially determine whether the sow is pregnant.

Observing the sow’s udder and teats

The udders of pregnant sows will become swollen and the color of their nipples may darken. This change is due to the increase in hormone secretion after pregnancy. Therefore, by observing the state of the sow's udders and nipples, you can preliminarily infer whether the sow is pregnant.

Perform an ultrasound examination

Ultrasound examination is one of the most accurate methods to determine whether a sow is pregnant. Ultrasound technology can be used to see the embryo in the sow's uterus and confirm pregnancy. It is generally recommended to perform an ultrasound examination between the 25th and 35th day of pregnancy for the best results.

Get a blood test

Blood testing is also a way to determine if a sow is pregnant. When pregnant, the sow's progesterone levels will increase, and the pregnancy can be confirmed by taking a blood sample to test the levels of these hormones.

Observe the weight changes of sows

Pregnant sows will gradually gain weight, especially in the late stages of pregnancy. Regular weighing can be used to observe the weight changes of sows and indirectly determine whether they are pregnant.

By combining the above methods, breeders can more accurately determine whether the sow is pregnant. Early confirmation of the sow's pregnancy will help to reasonably arrange feed, vaccination and other tasks to ensure the health of the sow and the growth and development of the offspring.
