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.

Highlights

The causative agents of gastrointestinal diseases are infectious agents of various nature: viral; bacterial; fungal and parasitic. [1, 3, 4, 9]The resistance of the virus in the external environment leads to long-term disadvantage of pig farms for this infection
If an acute outbreak occurs in dairy pigs, it is necessary to: 1) use broad-spectrum antibiotics to prevent bacterial overgrowth; 2) there must be sufficient fresh water; 3) weaning, if possible; 4) good sanitation Having milk in the intestines significantly reduces the osmotic diarrhea that develops
Glucose is passively absorbed even in the affected intestine; or you can give glucose and an aqueous solution orally as a source of energy to increase the time for epithelial regeneration

Summary

Introduction

The resistance of the virus in the external environment leads to long-term disadvantage of pig farms for this infection. Rodents and humans can be active or passive distributors of rotavirus infection. Most sows show antibodies against rotavirus in blood serum, colostrum, and mammary secretions. This group of pathogens includes porcine rotavirus [8, 10]. In this regard, the study of preventive and recreational measures for rotavirus infection is relevant. The aim of the study is to test the effectiveness of the Feed Back method in preventing rotavirus infection in suckling pigs. Objectives: 1. To study the methodology for preparing material for the feedback
