Abstract

The aim of the work is to experimentally find out in comparison the effect of two vaccines against circovirus infection Porcilis PCV and Circovac on the safety and weight gain of pigs in the rearing and fattening groups in the pig holding. The object of the study were 6687 pigs: 3393 heads vaccinated according to the instructions with the Circovac vaccine at a dose of 0.5 ml (group 1), and 3294 heads vaccinated according to the instructions with the Porcilis PCV vaccine at a dosage of 2.0 ml (group 2). In both groups, vaccination was carried out on the day of weaning on the 27-28 day of life intramuscularly in the neck area. When weaning, when transferring to fattening and before slaughter, the animals were weighed. According to the results of weighing, the average weight of animals was determined at 28 days, at 75 days and the weight at sale, as well as the average daily gain during rearing and fattening. Autopsy was performed on 209 fallen piglets from group 1 and 202 fallen piglets from group 2. During the pathoanatomic examination, a complex of pathoanatomic changes characteristic of circovirus was not found in any piglet. After vaccination of pigs in two groups with vaccines during the periods of rearing and fattening, there were no cases of cirrhosis among the livestock of both groups. The difference in indicators of case, technological marriage, average weight at weaning, average weight at transfer to fattening, average daily weight gain and weight at realization in the studied groups is minimal, not significant. Circovac vaccine in a dose of 0.5 ml proved to be no worse than the Porcilis PCV vaccine in a dosage of 2.0 ml.
