Ensuring veterinary well-being and productivity of pigs with an immunotropic drug

Abstract

The purpose of this work is to realize the productive qualities of young pigs by increasing the effectiveness of specific prevention of infectious diseases. The object of the study was 45 pigs of the Landrace breed from 14 to 171 days of age, divided according to the principle of pairs of analogues into 3 groups of 15 heads. The animals of the 1^st experimental group were injected with the immunotropic drug PigStim-V in a dose of 1.0 ml per head twice at the age of 14 and 21 days in order to stimulate nonspecific resistance of the body and increase the effectiveness of specific prevention of infectious diseases intramuscularly at the age of 14 and 21 days. Moreover, the second injection was carried out simultaneously with immunization against type 2 porcine circovirus infection. The tested immunotropic drug PigStim-V was administered to animals of the 2^nd experimental group once, at a dose of 1.0 ml per head at the age of 21 days simultaneously with a commercial vaccine against porcine circovirus. Animals of the 3^rd group served as biological control. The results of the study confirm the effectiveness of the use of the immunotropic drug PigStim-V as an adjuvant in the vaccination of pigs. Both single and double intramuscular injection of PigStim-V increases the titer of specific antibodies against porcine circovirus infection and against α, β and ε toxins of the microorganism Clostridium perfringens, prevents and increases the effectiveness of therapy of diseases of non-infectious etiology, stimulates growth. A more pronounced positive effect is observed with the double administration of an immunotropic drug.
