Description

technical field [0001] The invention relates to a chicken feed, in particular to a feed specially used for raising chickens in the open air. Background technique [0002] Raising chickens in the open air takes advantage of natural grasses, insects, earthworms, grass seeds and other resources such as grass hills, grass slopes, orchard woodlands, as well as the characteristics of good isolation conditions, less disease occurrence, high survival rate, and low investment. Lively, strong foraging characteristics, obtain part of the green feed and protein feed needed from nature, thereby reducing feeding costs and improving the economic efficiency of chicken breeding. However, the scale of farming is large, and the natural feed obtained in the open air is relatively small, and a large amount of supplementary feed is still required. However, most of the current supplementary feeds contain hormones and antibiotics, and chickens tend to have residues after eating, which affects the ...

AI Technical Summary

Problems solved by technology

However, the scale of farming is large, and the natural feed obtained in the open air is relatively small, and a large amount of supplementary feed is still required.

However, most of the current supplementary feeds contain hormones and antibiotics, and chickens tend to have residues after eating, which affects the original intention of raising chickens in the open air and reduces the quality of chicken

However, chickens must eat additives to improve disease resistance, so how to increase the appropriate feed for open-air chickens has become a difficult problem for farmers
