Problems solved by technology

Aiming at the current situation, the general solution is to take medicine frequently for epidemic prevention, which not only produces many negative effects, but also greatly reduces the immunity of laying hens, and the final result still seriously affects the breeding efficiency of laying hens

Embodiment Construction

[0015] The applicant has systematically studied the characteristics of physiological and endocrine metabolism changes of laying hens throughout the production cycle, egg production rules and their relationship with immune function, starting from coordinating the relationship between egg production traits and immune function, using Chinese herbal medicine and nutritional immunity The concept of "multiple sources and multiple effects" has developed a feed additive to enhance the immune function of laying hens and improve economic traits.

[0016] 1. Composition of feed additives:

[0017] The present invention starts from two aspects. One is a compound Chinese herbal medicine composition that clears heat and detoxifies, clears the veins and regulates qi, antibacterial and anti-inflammatory, promotes laying eggs, and enhances the overall immune function of laying hens. There are 15 kinds of honeysuckle, scutellaria, epimedium, yam, bupleurum, andrographis paniculata, licorice, pl...

Abstract

The invention discloses a feed additive and application thereof in the disease-resistance and yield increasing of laying hens. The produced feed additive is prepared by pulverizing compound Chinese medicinal composition and nutritive composition in a weight ratio of 1:1 to comprehensively regulate the metabolic mechanism in the laying hens, enhance the immunologic function of the laying hens and improve the egg-laying performance. Due to the adoption of the feed additive, the egg yield is increased by 12.4 percent; the death rate is reduced by 6.8 percent; the feed / egg ratio benefit is increased by 9.4 percent, so that the indexes of the quality of the eggs are more excellent than those of the control group obviously; the immunologic function of the laying hens is improved greatly; the probability of disease infection is reduced obviously; even if in the common disease infection period, the decline rate of the egg yield of an experimental group is 13.8 percent less than that of the control group; and the comprehensive use effect is very obvious.

Description

technical field [0001] The invention belongs to the animal husbandry technology in the field of agriculture, and specifically relates to a feed additive and the application of the feed additive in regulating the production and disease resistance of laying hens through feeding methods. Its core is to solve the problem of frequent Immune function generally declines due to immunization and seriously affects production. Background technique [0002] At present, the production of laying hens in my country is mainly based on the "small-scale" scattered breeding pattern in rural areas, and its fatal flaw is mainly manifested in "chaos". It is precisely because of the "chaos" that the biological safety environment of laying hens in the main production areas has become more and more complicated, resulting in frequent occurrence of diseases and seriously affecting normal production. The cost of healthy breeding for farmers is increasing. Many ordinary people either use vaccines to pr...
