Prepare pigs for fattening before preparation: generally include: disinfection, castration, vaccination, deworming, etc.
The pigs can be divided into three stages according to their growth and development stages: pig stage (growth stage of 20-35 kg body weight), middle pig stage (growth stage of 36-60 kg body weight), and pig stage (weight 61- For a fattening period of 90 kg or more, the piglet phase is one of the keys to good fattening pigs. To ensure the healthy growth and development of fattening, the following preparations should be made.
1. Septic disinfection: The purpose is to avoid infection of pigs from infectious diseases and parasites. Before disinfection, do a good job in the maintenance of the sheds, eliminate fecal matter, bedding, etc., flush the ground with water, and then disinfect the sheds, floors, and walls.
Disinfection method: 1 Spray with 3% caustic soda water. 2 Brush the walls with 20% lime milk.

If they are purebred lean pigs, the sows do not castrate, because these pigs grow fast and can reach slaughter weight when they are not mature.
3. Vaccination: Pigs used as fattening pigs must be given two swine fever vaccine injections before the transfer stage, and other injections of bacteriological vaccines should be carried out at the time of transfer. Later, they can be based on the epidemic situation. The technical department puts together other epidemic vaccines in order to prevent more serious infections and ensure the healthy growth of pigs.
4. Insecticide: When the hog enters the pen, it is used to dispel the parasites in one time, and the insects are repelled once every 2 months. The drug can be administered at night by using 1 levigozole hydrochloride tablets at a dose of 1 tablet per 3 kg of live pig weight and a small amount of better feed. 2 levamisole phosphate injection, injection of 5 mg per kilogram of body weight.
Ectoparasites (Cockroach, Gardenia, etc.) may be coated or sprayed with Bainilin (mainly composed of ivermectin and albendazole) and 1.5% solution of trichlorfon.
