2.Pig farms do not pay attention to epidemic prevention work, technical personnel have poor health care concepts, do not strictly close pig farms, and do not carry out systematic health care of pig herds.
3.The weight of the diseased pigs is generally 20 80kg, and the incidence is the highest, and there are also piglets after weaning.
4.The effect of the drug ** is not ideal, and the mortality rate of the pig farm is higher in the indiscriminate use of the drug.
Prevention and control measures. Blue round nucleic acid peptide (GuocoHi-Tech) and concanavalin ** porcine PRRS and circovirus disease are used.
1.On the morning of the first day, the diseased pigs were injected with the blue circle nucleic acid peptide cephalosporin pioneer according to the proportion of each kilogram; In the afternoon, concanavalin (6 million unit bottles, each bottle is diluted with 5 ml of Bupleurum injection when used), and 1 million units per 10 kg were injected intramuscularly.
2.The second day, the same as the first day.
3.On the third day, canavalin (6 million unit bottles, each bottle is diluted with 5 ml of Bupleurum injection when used), 1 million units per 10 kg were injected intramuscularly.

What kind of vaccine is injected? It should be decided according to the local epidemic situation: one month before the insemination of gilts, pig parvovirus oil emulsion inactivated seedlings.
Pseudorabies gene deletion vaccine. 25 to 30 days before mating Two months before the breeding of pseudorabies gene deletion vaccines: porcine parvovirus inactivated seedlings, maternal antibodies in piglets can reach 14 to 24 weeks.
Every year in April swine fever.
Pneumonic disease, erysipelas.
Triplet II. Multiparous sows 1. Prenatal 20-30-35 days : infectious gastroenteritis - epidemic diarrhea aluminum hydroxide.
