Application of drug composition in preparation of drugs for preventing salmonella infection in laying hens

Abstract

The invention provides an application of a drug composition in the preparation of drugs for preventing salmonella infection in laying hens, improving egg laying performance of the laying hens, reducing the amount of salmonella in shells and contents of eggs and improving quality of the eggs of the laying hens. The drug composition comprises, by weight, 20-50 parts of gallnut tannic acid and 10-30parts of glycine. The drug composition has the advantages of green safety and no tolerance by taking 'source conditioning' as the core; replacing antibiotics, the drug composition can effectively inhibit and kill salmonella, eliminate endotoxemia caused by bacterial death and release of endotoxin, adjust the body's immune defense, purify salmonella from the laying hens, reduce horizontal spread ofsalmonella and egg-borne contamination caused by potential endogenous displacement of chickens, improve egg laying performance and the quality of the eggs and effectively avoid food safety problems caused by the egg-derived salmonella.

Description

technical field [0001] The invention belongs to the technical field of veterinary medicine, and in particular relates to the application of a pharmaceutical composition in the preparation of medicines for preventing and treating Salmonella infection in laying hens. Background technique [0002] Food safety problems caused by foodborne pathogens have been paid more and more attention, among which, food safety problems caused by Salmonella are an important reason that has plagued the healthy development of the poultry industry for a long time. In the United States, large-scale egg recalls have brought Salmonella infection in eggs into the focus of food safety again. Salmonella can infect eggs through vertical transmission and horizontal transmission. Salmonella infection caused by eggs is considered to be one of the main causes of Salmonella infection in humans. Under normal circumstances, the elderly, children, and some immunocompromised patients are susceptible to Salmonel...
