Dosage of classical swine fever vaccine

Pig farmers need to be vaccinated regularly to avoid economic losses caused by classical swine fever. The dosage of classical swine fever vaccine should be appropriate, so how much is the dosage of classical swine fever vaccine?

I. dosage of classical swine fever vaccine

When using the vaccine, it is necessary to add diluent or sterile saline to each portion according to the first portion of the vaccine instruction. And inject it into the pig. The dosage should be determined according to the actual situation.

2. Types of classical swine fever vaccine

At present, there are three main vaccines to prevent classical swine fever on the market:

1. Live classical swine fever vaccine (I)-suckling rabbit vaccine.

two。 Live classical swine fever vaccine (II)-cell vaccine.

3. Live classical swine fever vaccine (I)-spleen vaccine.

III. Immunization process of classical swine fever vaccine

1. In the areas where there was no epidemic of classical swine fever, one piglet was first exempted from 20 days old to 25 days old, and one from 60 days old to 65 days old. The reserve pigs were immunized once before mating at the age of 8 months, 1 dose per pig. Breeder boars and sows were immunized every 6 months, and sows were vaccinated during the empty pregnancy period after weaning (10-14 days before general mating).

two。 In the epidemic area of classical swine fever: the newborn piglets were pre-immunized, that is, 2 piglets were vaccinated immediately after birth, followed by breast feeding after an interval of 1 hour, and 1 part of 35-40-day-old piglets were immunized. The reserve pigs were immunized once 6 months after the second immunization before mating, with 1 serving per piglet. Breeder boars are immunized once every six months, each with 1 dose. Breeder sows were immunized once in the empty pregnancy period after weaning, 1 dose per sow.

IV. How to get the classical swine fever vaccine

1. Usage of suckling rabbit vaccine: the vaccine is injected intramuscularly or subcutaneously. When in use, mark the first portion according to the bottle label, dilute it with sterile normal saline at 1 ml per serving, and 1 ml for both pigs and pigs. The vaccine is prohibited from being injected with the vaccine at the same time. A few pigs may react within 1 ~ 2 days after injection of this vaccine, but it can return to normal after 3 days. If there is an allergic reaction after vaccination, anti-allergic drugs such as epinephrine should be injected in time.

The vaccine should be kept away from light under-15 ℃ and is valid for 12 months. After dilution, the vaccine should be placed in a refrigerated container and should not be frozen. If the temperature is below 15 ℃, it should be used up within 6 hours; if the temperature is 15 ℃-27 ℃, it should be used up within 3 hours. The better time for injection is 2 hours after eating or before eating.

two。 Usage of spleen vaccine: the vaccine is injected intramuscularly or subcutaneously. When in use, mark the first portion according to the bottle label, dilute it with aseptic normal saline at 1 ml per serving, and 1 ml for both pigs and pigs. The vaccine should be kept under-15 ℃ and valid for 12 months. After the vaccine is diluted, it should be placed in a refrigerated container and icing is strictly prohibited. If the temperature is below 15 ℃, it will be used up within 6 hours. If the temperature is 15 ℃-27 ℃, it should be used up within 3 hours. The better time for injection is 2 hours after eating or before eating.

3. Usage of cell vaccine: the vaccine can be used in both pigs and pigs. The first portion is marked according to the label. 1 ml of aseptic saline is added to each part and diluted, and 1 ml is injected subcutaneously or intramuscularly to all pigs. Immunity can be produced 4 days after injection, and the immune period can be up to 12 months after injection. The vaccine should be kept below-15 ℃ and valid for 18 months. It should be known that there is no epidemic in the area before injection. With dilution, the diluted vaccine should be put in a cold dark place and be used up within 2 hours. Pre-weaning pigs can be vaccinated with 4 doses of vaccine to prevent maternal antibody interference.

We should choose different vaccines according to different conditions, and the dosage of different vaccines is also different, so we should choose according to the actual situation.
