What is a fake pregnancy?

Sows do not get pregnant after breeding, but their bellies get bigger day by day, and their breasts gradually expand. In the end, they can even squeeze out some clear milk, but they do not give birth, and their bellies and breasts gradually retract. This phenomenon is called false pregnancy.

Causes of false pregnancy:

First, due to early embryonic death and absorption, and the corpus luteum of pregnancy does not disappear, resulting in progesterone secretion, as if pregnancy is still continuing.

Second, due to malnutrition, the endocrine disorder of sows is caused, and the estrous cycle of sows is delayed or stopped.

How to prevent and cure false pregnancy?

The prevention and treatment of false pregnancy is mainly to improve the nutritional conditions of sows before and after mating, prevent and treat reproductive tract diseases of sows, and keep warm in winter. For the treatment of persistent corpus luteum, 5 mg of prostaglandin and 1000 units of pregnant horse serum can be injected into sows.
