(agricultural get Rich Network) what problems should be paid attention to before and after introduction? -- customers should do a good job of disinfecting and isolating pig pens before introduction. If it is a newly built farm, carefully disinfect it with caustic soda or lime milk once or twice after completion. If it is an old farm, the isolated pig house had better be empty for more than three months, and it should be thoroughly cleaned and repeatedly disinfected. If conditions permit, the isolated pig house should be as far away from the original pig herd as possible. After the introduction, feed the pigs according to the size of the pig. Don't feed too much feed on that day, just provide adequate drinking water. It was managed and fed by special personnel, and some broad-spectrum antimicrobials, such as oxytetracycline 1000g/ tons, were added to the feed for 10 days. After a week, after the breeder pig's appetite and spirit fully return to normal, the injection of classical swine fever, Japanese encephalitis, parvovirus and pseudorabies can be arranged. Parvovirus, je and pseudorabies vaccines can be boosted 2 weeks after the first injection. At least 18 days after the last injection of the vaccine, the immunization of other vaccines shall be dealt with as appropriate according to the epidemic situation of the local disease. About 45 days after introduction, the feces of the original herd can be inoculated into the new herd, and the mixed herd can not be mixed until there is no abnormal reaction for a period of time.
