Technology of Aerogenic Immunization against Swine Erysipelas under Conditions of Actual Practice

Large animal husbandry centers are economical only with high concentration of the herds. The facilities for animal raising must be so protected that infectious diseases do not lead to an endangerment of the herd. In this regard, stringent isolation and prophylactic vaccinations are of importance. The prevention of swine erysipelas infection in large pig-fattening facilities cannot be solved through hygienic measures alone. The animals must be kept under vaccine protection against swine erysipelas, since, in spite of all therapeutic measures, spontaneous outbreaks of swine erysipelas among non- immunized pigs can lead to a considerable loss of animals. Consequently a method must be sought which will immunize large numbers of hogs without syringe and cannula.
