Description

technical field

[0001] The invention relates to the technical field of chicken feed processing, in particular to a chicken feed with functions of promoting growth and improving immunity and a preparation method thereof. Background technique

[0002] At present, with the development of intensive farming industry, the scale of broiler farming is getting larger and larger. The high-density intensive breeding mode also makes the ecological system structure of the breeding environment single, and the resistance of broilers is weak. Once a disease occurs, it is very easy to cross-infect and spread on a large scale, causing huge economic losses to the farmers. The modern large-scale animal husbandry raising method has increased the production speed, but it has also brought many problems. The quality of livestock products is lowered, and livestock and poultry are prone to various diseases, and a large number of antibiotics and additives in the feed are harmful to human health. These...
