POLYMICROBIAL AND POLYVIRUS ASSOCIATIONS IN PIGS OF DIFFERENT AGES WITH SIGNS OF RESPIRATORY PATHOLOGY ON THE EXAMPLE OF SEVERAL PIG COMPLEXES FOR 24 THOUSAND HEADS

Abstract

The article presents data on the study of the viral-bacterial profile in pigs of different ages in the farms of the Republic of Belarus. It has been established that the maximum number of PRDC pathogens in most households is iso-lated at the age of 60−80 days, bacterial pathology accumulates gradually and, as a rule, is a secondary infection (with the exception of IAR).
 The viral and bacterial profile depends on the epizootic situation in the farm, the most complete list of CRPC pathogens (11 out of 13) was observed in farm No. 4. Primary detection in samples of 60−80 day old piglets of the APP pathogen genome indicates its later infection compared to hemophiliasis pathogens and IAR. Infection with the causative agent of IAR presumably occurs in the post-weaning period up to 40 days.
