Usage of “Feed Back” as an ecologically safe and effective means for preventing rotoviral infection of piglets

Abstract

Diseases of the gastrointestinal tract in newborn piglets cause enormous economic damage to countries where pig breeding is intensively developed. The high pathogenicity of the causative agents of these diseases, their resistance in the external environment, the ability to persist in the host organism leads to the rapid spread of these diseases. In our work in a pig farm, the effectiveness of the use of “Feed Back” (reverse feeding) for the prevention of rotavirus infection in suckling pigs was assessed. “Feed Back” or reverse feeding is feeding pregnant sows and replacement pigs material for re-infecting animals with infectious agents necessary for us: clostridiosis, colibacillosis and rotavirus infection with the subsequent transmission of colostral immunity to piglets. The purpose of this method is to enhance the action of the vaccines used and develop colostral immunity to those diseases against which vaccines are not used.
