There are many types of cockroaches, including licking, licking, toe, and quail eggs, among which cockroaches are common. Because chicken feathers can cause bruises and bleeding, and secondary infections in chickens cause problems such as increased mortality. Therefore, the following measures must be taken in time to respond positively:
(A) to grasp the appropriate breeding density, especially broiler chicken, to give a certain space for activities, chicks grow up to a certain stage to be timely grouping.
(2) The feed must be fully priced and balanced to ensure the nutritional requirements of the chick's development.

With the development of the extraction and separation of the active ingredients of medicinal plants, the determination of their composition and structure, and the study of their pharmacological effects, some isolated and purified plant extracts have begun to receive attention. Some companies that produce plant extracts are actively researching and developing such new products, and some larger cosmetic companies have also carried out a lot of research work to separate and prepare pure extracts and apply them to various products. These plant extracts have high active ingredients, do not contain or less contain other irrelevant substances, contain one or several relatively pure components, the content and structure of the components are accurate, and there are clear quality standards and inspections. Methods, products have undergone pharmacological tests, clinical trials and activity tests. The use of such plant extracts is more effective and practical, and it is convenient for product preservation and quality control, but the cost is higher than that of general extracts. The following discusses some of the isolated and purified plant extracts that are used in cosmetics and whose components and structures are well understood.
Due to the influence of traditional Chinese medicine culture, my country's Plant Extract industry has unique development advantages. With abundant resource advantages and technological advantages, China has become one of the most important suppliers of plant extracts in the world.
