How to treat sows that do not come into heat? Detailed introduction to treatment options

Estrus in sows is an important prerequisite for breeding and producing piglets. If a sow does not come into heat, farmers must pay attention and regulate her condition according to treatment options. Below, let us understand what are the causes of sows not coming into heat?

What are the treatment options for sows not coming into heat?

First, massage the sow, massaging both sides of her udder or the subcutaneous mammary layer; second, use a boar to induce her, allowing the boar to contact the sow for 15-30 minutes each day; third, feed brown sugar, adding boiled brown sugar water to her pig feed and feeding it for one week; fourth, feed Zengzai pills, once a day, 2 pills each time; fifth, group her with sows that are in heat so she enters the state as soon as possible.

What are the causes of sows not coming into heat?

1. The sow shows no signs of estrus

The main reason is that the sow secretes too little progesterone or none at all, which cannot stimulate the sow's physiological response and thereby induce estrus.

2. The sow is in heat but will not allow mating

This is because the sow has a certain amount of progesterone; although it stimulates signs of estrus, the amount secreted is limited and not enough to prompt ovulation, thus causing the sow to be unwilling to mate.

3. The sow comes into heat repeatedly but fails to conceive after mating

This is because in the early stage of estrus, progesterone secretion in the sow's body is normal, but after mating, due to subsequent secretion disorders of progesterone and other hormones, the fertilized egg cannot implant normally, resulting in failure to conceive after mating or repeated return to estrus.

In addition, when treating sows that do not come into heat, be sure to pay attention to scientific management. Those with insufficient experience can consult relevant agricultural technicians or veterinarians.
