How old is the sow to breed?

Sows can be mated about 1-2 months after proestrus, and the more suitable mating time is about 2-3 hours before ovulation or 21-22 hours after estrus.

It can be said that the sow is very important to a pig farm. If the sow is mated at the time of breeding, it is half successful. The time of mating of the sow at each stage is different, while the sow can be mated 1 to 2 months after proestrus, that is, 1 to 2 months after the sow is 5 to 8 months in estrus.

How old is the sow to breed?

1. Sows can be mated about 1 to 2 months after proestrus, while the proestrus of sows is when they are five to eight months old, because there are many pig breeds, some of which even reach proestrus at the age of three months. and basically have the ability to reproduce, but it should be noted that if the sow has not yet reached maturity, the weight is usually relatively small, at this time reluctantly to mate. It will bring some heavier burden to sows, resulting in fewer piglets and reducing fertility in the later stage.

2. From the point of view of reproductive physiology, when sows are in estrus, the most suitable time for breeding is 2 to 3 hours before ovulation, or between 21 and 22 hours after estrus. This period is the most suitable for breeding. Check whether the sow is in estrus or not, and you can observe whether the gilt's vulva has changed from red to purplish red, swelling fades and wrinkles appear. There is also whether the sow vulva has fluid, and so on. When this symptom occurs, it is the best time for sows to breed.

During the period of sow breeding, first of all, you need to judge whether the sow is in estrus or not, and judge the specific mating time according to the time of estrus. The yield and piglet quality of this sow are very helpful.
