The purpose of this experiment is to study the effect of traditional Chinese medicine feed additives with the same medicine and food on the production performance, egg quality and economic benefits of laying hens. Firstly, formulate a prescription based on the nature, taste, meridian, and function of Chinese medicine. After many small-scale breeding experiments, the effect is continuously tested and then selected to be a medicine that can comprehensively improve layer production performance, egg quality and economic benefits. Feed additives of traditional Chinese medicine for eating homologous layers. 400 30-week-old Roman brown-shell hens with similar morphology, good physical condition, and basically the same weight was selected and randomly divided into four groups, each with 100 chickens, with 5 repeats in the group, the first group was the control group (CK), the second, third, and fourth groups are experimental groups, denoted by A, B, and C respectively. The control group was fed only the basal diet, and the experimental groups A, B, and C were fed with 0.3%, 0.5%, and 1% of the above-mentioned medicinal and food homologous layer Chinese medicine additives on the basis of the basal diet, respectively. The test found that compared with the control group, the egg shell thickness, Hastelloy unit, egg shape index, egg yolk color, egg yolk ratio, protein content in eggs and lecithin content in egg yolks were increased in the experimental group compared with the control group, and the cholesterol content in the egg yolk decreased significantly; The egg production rate and average egg weight have been improved, the feed-to-egg ratio has been reduced, and the economic benefit has been significantly increased; the serum SOD, T-ACO, and IgG content of laying hens have been significantly increased, and the MDA content and total cholesterol content have been significantly reduced. It can be seen that the traditional Chinese medicine feed additive for layers with the same medicine and food can effectively improve the production performance of layers, improve egg quality, enhance the body resistance of layers, and increase economic benefits. In this experiment, it is better that the 1% addition amount has the most comprehensive effect.
