Vaccine-free method for breeding laying hens

Abstract

The invention discloses a vaccine-free method for breeding laying hens. The basic management method and management condition are the same as the conventional laying hen management method, however, novaccination is carried out during a breeding process, and corresponding traditional Chinese medicine compositions are added to the daily diet of the laying hens according to the ages of the laying hens in days. The method is simple and easy, the complicated vaccine immunization procedure of the laying hens is eliminated, and a large amount of labor and vaccine expenditures are saved. From the birth of the laying hens, the traditional Chinese medicine compositions are used to condition the immunity of laying hen bodies, the physiques of the hen bodies are enhanced, and the death rate of the henbodies due to vaccination is reduced. According to the method, the feed conversion rate of the hen bodies can be greatly increased, the profit rate of the culture is increased, at the same time, no antibiotics is used in the whole laying hens breeding process by employing the method, therefore, the antibiotic residue in the laying hen bodies and eggs are reduced to zero, the safety of foods is guaranteed, and the method makes a great contribution to the protection of ecological balance and human health and has extremely high economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of animal feed for livestock and poultry, in particular to a method for raising laying hens exempt from vaccines.
