What factors affect the number of piglets a sow farrows
With the continuous development of modern society, pig farms are paying more and more attention to scientific pig farming, seeking more effective pig-raising methods through a series of scientific studies to promote an increase in the number of piglets a sow farrows and the birth weight of the piglets. So what are the factors that affect the number of piglets a sow farrows? Let's take a look together.
1. Breed
The breed of the breeding pig is an important factor affecting the number of piglets a sow farrows and the birth weight of the piglets. Influenced by genetic factors, when good breeding boar semen is used to inseminate the sow, the number of piglets farrowed is very high, the survival rate of the piglets is also very high, and the economic benefits brought to the pig farm are also considerable. Pig farms should promote an increase in the number of piglets while ensuring piglet quality. To give full play to the maximum effect of heredity, pig farms should select breeding pigs of superior breeds to inseminate the sows.
2. Sow nutrition
The nutritional status of the sow seriously affects the number of piglets she farrows. Only when the sow receives an adequate nutritional supply will she have a good physiological state. During fertilization, embryo implantation and embryo development, large amounts of nutrients are needed, and all of these affect the number of piglets farrowed. According to surveys, feeding sows a high-protein feed 10 days after mating can maximize the ovulation rate and the number of piglets farrowed. Within 2-3 days after mating, too much feed must not be given, otherwise it will reduce the embryo survival rate.
3. Living environment
If a sow has a good living environment, it will greatly increase the sow's farrowing rate. Among environmental factors, temperature has the greatest impact on the number of piglets farrowed. If the sow lives in a high-temperature, high-humidity environment, it will greatly reduce the number of piglets the sow farrows and the birth weight of the piglets. Therefore, if the sow lives in a high-temperature, high-humidity environment, it will greatly reduce the number of piglets the sow farrows and the birth weight of the piglets.
