Description
Technical Field
The invention relates to the technical field of feeds, in particular to a broiler compound feed without antibiotics.
Background
The use of feed antibiotics has been considered the most prominent biotechnology in animal husbandry in the 20 th century. Since streptomycin was first reported to stimulate the growth of chicks in 1946, after the U.S. Food and Drug Administration (FDA) first approved antibiotics as feed additives in 1950, antibiotics were widely popularized and applied as feed additives while being largely used for the treatment and prevention of bacterial diseases. However, as antibiotics are abused in large doses for a long time and the antibiotics for feeding are studied more deeply, various disadvantages of the antibiotics are gradually recognized. Especially in recent years, the events caused by the problem of feed safety are becoming more and more interesting worldwide, and the addition of antibiotics to feed is being opposed by more and more scientists and stockbreeders.
In the process of large-scale breeding of broilers, the feed antibiotics play an important role in guaranteeing the health of the broilers, promoting growth and improving the production performance of the broilers, but meanwhile, the improper use of the feed antibiotics also causes bacterial drug resistance, and the problem of animal-derived food antibiotic residue causes serious harm to people and ecological environment.
It is clear that the 194 bulletin of Ministry of agriculture has started from 7/1 of 2020, and feed production enterprises stop producing commercial feeds containing growth-promoting drug feed additives (except traditional Chinese medicines), meaning that feeding antibiotic products are prohibited from being added into the feeds. The main problem of broiler chicken breeding after feed antibiotics are stopped is intestinal health, so that a safe, green and efficient broiler chicken compound feed product is needed to be developed, the problems of broiler chicken diarrhea, feed excrement, dyspepsia and the like are solved, and the high productivity of broiler chickens is maintained.
