| Abstract:
|
To study the influence of vaccinations against porcine cycrovirus 2 (PCV2) by vaccines of two different manufacturers on leukogram and level of specific antibodies in blood of pigs at the Pavlovsky Pork Complex of the Bryansk Oblast 2 groups of 15 heads of weaning pigs of 21 day old were formed. Inactivated vaccines were injected intramuscularly into the neck region: animals of group 1 - Suvaxyn PCV2, pigs of group 2 - Ingelvac CircoFLEX. Blood was taken from 15 animals from each group from the femoral vein in the morning before feeding: for morphological study - before the beginning of the experiment and further every 14-15 days up to 125 days after vaccination; for determination of antibodies titer - 21, 60, 90 and 120 days after vaccination. It has been established that the mechanism of cellular antiviral protection is expressed to the greatest extent when using the Ingelvac CircoFLEX vaccine, and the highly specific humoral protection and higher reactivity of pigs' organism in relation to technological stress in a remote period after vaccination - after application of Suvaxyn PCV2.
