Description

Breeding method for improving immunity of pork pigs

Technical Field

The invention belongs to the technical field of pork pig feeding, and particularly relates to a breeding method for improving immunity of pork pigs.

Background

The pig breeding belongs to livestock breeding in the traditional field, but with the continuous development of the breeding industry, the requirements of the pig breeding technology have been continuously developed and innovated from the traditional breeding field, so that the development of the pig breeding industry gradually develops towards the directions of high technology, high quality, low energy consumption, low cost, environmental protection and the like.

Because the breeding environment is poor in the pigsty, the pigsty condition is poor, the odor is thick, a large amount of mosquitoes are bred, the mosquitoes are first fierces of spreading of swine plague, the disease threat is finally large, and the final output value is influenced, so that improvement is needed, on one hand, the safety of the feed is improved, on the one hand, the breeding environment of the pigsty is improved, real safe and healthy breeding is realized, and finally, the natural immunity and disease resistance of the pigs are improved.

In the process of raising pork pigs, in order to reduce the fatality of the pork pigs, a plurality of farmers use a large amount of antibiotics in the raising process to reduce the disease of the pork pigs, and use various synthetic drugs for treating the disease of the pork pigs, however, the antibiotics or drugs can also remain in the pork, which affects the quality of the pork and even seriously threatens the health of human beings eating the pork for a long time.
