Abstract

The invention relates to a feed additive and a preparation method thereof, belonging to the technical field of feeds. The feed additive is characterized by comprising the following substances in percentage by weight: 40 percent to 60 percent of dogwood, astragalus, medlar and licorice extract, 30 percent to 50 percent of honeysuckle flower, cortex eucommiae, okra and mimosa pudica extract, 5 percent to 10 percent of fish meal, 0.5 percent to 1 percent of selenium yeast, 0.1 percent to 0.5 percent of compound vitamins, 0.1 percent to 0.2 percent of compound amino acids and 2 percent to 5 percent of spirulina. The feed additive has the advantages of rich raw material sources, low price, no toxic or side effects, effects of preventing various diseases of laying hens and improving immunity and disease resistance of the laying hens, environment-friendliness, high safety, high laying rate, high laying quality, high survival rate of the laying hens, enrichment of selenium, iodine, zinc and other nutrient elements, and the like.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a feed additive and a preparation method thereof. Background technique [0002] Feed additives refer to the addition of a certain amount of substances in the process of feed processing and production. The function of this feed additive can be to increase nutrition, improve yield and quality, prevent disease infection and so on. In recent years, with the continuous development of the laying hen farming industry, the farming techniques of some professional laying hen farmers have been unable to keep up with the rapid development level of the growing farming industry, and various non-standard breeding methods lead to low egg production of laying hens , egg production quality and nutritional value are not high, and laying hens are susceptible to various diseases, such as chicken plague, avian influenza, infectious bronchitis, etc., resulting in a decrease in the survival rate of laying...

Problems solved by technology

In recent years, with the continuous development of the laying hen farming industry, the farming techniques of some professional laying hen farmers have been unable to keep up with the rapid development level of the growing farming industry, and various non-standard breeding methods lead to low egg production of laying hens , egg production quality and nutritional value are not high, and laying hens are prone to various diseases, such as chicken plague, avian influenza, infectious bronchitis, etc., resulting in a decrease in the survival rate of laying hens

In order to significantly increase the lean meat mass of broilers, some professional chicken farmers abuse harmful substances such as clenbuterol; Synthetic drugs and other substances, the long-term use of these feed additives will not only cause drug resistance of pathogenic bacteria, but also leave harmful drugs in the chicken body and eggs, which has certain toxic and side effects; the abuse of hormone-containing protein feed additives, Its residual hormones also make eggs and egg products have greater safety hazards, which will bring harm to the health of humans who use eggs, and affect the export of my country's livestock and poultry products and the development of laying hen breeding industry
