What are the factors that affect the number of sows born

With the continuous development of modern society, pig farms pay more and more attention to scientific pig raising, and seek more effective pig raising methods through a series of scientific research to promote the increase of litter size and birth weight of sows. So what are the factors that affect the litter size of sows? Let's get to know it.

1. Variety

The breed of breeding pig is an important factor affecting the litter size and birth weight of sows. Affected by genetic factors, good semen of breeding pigs is adopted to inseminate sows. The number of piglets produced by sows is very high, and the survival rate of piglets is also very high. The economic benefits brought to the pig farm are also considerable. Pig farms should promote the improvement of litter size on the premise of ensuring the quality of piglets. In order to maximize the genetic effect, pig farms should select excellent breeds of pigs to inseminate sows.

2. Nutrition of sows

The nutritional status of sows seriously affects the litter size of sows, only sows get sufficient nutrition supply, which will make sows have a good physiological state and need a lot of nutrition during fertilization, embryo implantation and embryo development. and all these affect the number of litters. According to the investigation, sows fed with high-protein diet in 10 weather can maximize the ovulation rate and litter size, and do not feed too much feed within 2-3 breeding, otherwise it will reduce the survival rate of embryos.

3. Living environment

If sows live in a hot and humid environment, the litter size of sows and the birth weight of piglets will be greatly reduced.
