DETERMINATION OF THE HARMFUL AND TOXICITY OF THE VACCINE AGAINST ECHERICHIOSIS, PSEUDOMONOSIS AND INACTIVATED ENTEROCOCCAL INFECTION OF PIGS
This paper presents the research on the study of the chronic toxicity of the vaccine against Escherichiosis, pseudomonosis, inactivated enterococcal infection of piglets in laboratory animals, as well as the study of acute toxicity and reactogenic effect on pigs of the Large white breed. It was found that a single administration of the vaccine in 1-5 times doses to pregnant sows and suckling piglets did not cause signs of acute toxicity, anaphylactic reactions, abscesses, abortions and mortality.
