Detailed Explanation of Cross-Infection and Safe Injection Issues in Pigs
(1) Sterilization of vaccination equipment. Syringes, needles and other vaccination equipment must be strictly sterilized and disinfected according to requirements.
(2) One pig, one needle. Strictly guard against the one-needle-to-the-end injection method. It is best to use one pig, one needle, changing the needle for each pig injected.
(3) Order of emergency vaccination. During emergency immunization, vaccination should be carried out in the order of relatively clean herds; assumed healthy herds; threatened herds; and affected herds. Within an affected herd, proceed in the order of asymptomatic; mildly symptomatic; and severely symptomatic.
(4) Safe and scientific injection issues. Intramuscular injection at the side of the neck behind the ear.
(5) Immunization issues for pregnant pigs. Under normal circumstances, immunization should be avoided as much as possible during sow pregnancy, except for emergency immunization.
