Description

Technical Field

[0001] The invention relates to aquatic animal feed, in particular to a feed for Procambarus clarkii and a preparation method thereof. Background Art

[0002] In recent years, in order to meet people's consumption needs, aquaculture has been developing towards intensive farming. High-density farming can easily lead to stress, decreased immunity, frequent diseases and other problems in aquatic animals. Although the use of antibiotics has a direct bactericidal and growth-promoting effect, it can also easily lead to a series of problems such as environmental pollution, residual hazards, and easy bacterial resistance. Therefore, antibiotics are currently banned in feed.

[0003] Chinese herbal medicine has many advantages such as being green, safe, and efficient, and is a potential substitute for antibiotics. Eucommia leaves, like the commonly used Eucommia bark, have active substances and are also a renewable, low-utilization Chinese herbal resource with a large annual output. Studies have shown that Eucommia leaf extract, as a new type of Chinese herbal additive, can improve the growth performance, immunity, and muscle quality of farmed animals. In order to find feed additives that replace antibiotics, the method of effectively utilizing Eucommia leaf resources can be adopted. Summary of the invention
