Feeding management. In each growth period, feed as required, and quantify regularly. Feeding the national certified total nutrient compound feed. Careful management. Observe carefully. When problems are found, they should be solved in time. There must be no delay. Choosing a good parent breed, there is a saying that "boars have good slopes and sows have good nests." Good varieties have the advantages of strong disease resistance, fast growth and high lean meat rate. The selection of pig breeds should have good economic value. We should choose breeding pigs with strong physique, healthy limbs, high meat yield, good meat quality, short growth period, saving feed, not picky eaters and strong ability to resist epidemics.

Breeders should learn veterinary knowledge, regularly inspect the pigsty, check the sanitary condition of the pigsty, observe the pig's diet and defecation, and observe the pig's activities and expressions. The protection rate and effect of each vaccine are different, and the price is also very different. For example, the vaccine for asthma, Pfizer's vaccine is much more expensive than the general vaccine, and only some big manufacturers choose to use it.

Doing a good job of sanitation in pigsty and regular disinfection can kill pathogens, reduce the chance of contact with pathogens and prevent the occurrence and infection of epidemic diseases. The pigsty can be disinfected with 2-4% caustic soda solution or 10-20% lime water. Sites, corpse ponds and septic tanks inside and outside pig farms need to be mixed with quicklime (10- 15%) and caustic soda (2-3%) and disinfected with sorghum brooms.

According to the scale of the pigsty, the breeder should make a blood collection plan, scientifically evaluate and manage the health status of pigs, and accurately know the timing of vaccine immunization, so as to know the effect of immunization, the effective time of antibodies and so on. African swine fever is the biggest enemy of domestic pig industry at present, which leads to heavy losses in domestic pig industry. If you want to raise pigs now, you must pay attention to African swine fever, especially the introduction, which increases the risk of infection. After the introduction of swine fever vaccine, we must do a good job of inquiry and testing, and then wean the piglets and turn around. Under normal circumstances, in order to prevent the pressure of piglets from turning around, sows are often turned around, and piglets are allowed to stay in the original pen for a period of time, and then transferred to the fattening pen.
