Traditional Chinese medicine composition for freshwater shrimp feed

Abstract

According to the technical scheme adopted by the invention, the traditional Chinese medicine composition for the freshwater shrimp feed is characterized by being prepared from the following components in percentage by weight: 20%-25% of astragalus, 10%-15% of Chinese yam, 5%-10% of Chinese angelica, 5%-10% of honeysuckles, 10%-15% of codonopsis pilosula, 10%-15% of radix ophiopogonis, 10%-15% of hawthorns, 5%-10% of dried tangerine or orange peel and 10%-15% of isatis roots. The selected Chinese herbal medicine contains various immune active substances, can be used for promoting the freshwater shrimps to feed, increasing the feed utilization efficiency, strengthening the disease resistance of the freshwater shrimps and improving the survival rate of the freshwater shrimp breeding; the traditional Chinese medicine composition is added into the feed, free of toxic and side effect, free of drug resistance and drug residue, and capable of providing the freshwater shrimps which can improve the safety and the health of people. The traditional Chinese medicine composition adopts easily available raw materials, is convenient to manufacture, good in using effect and has a popularization value.

Description

technical field [0001] The invention relates to the field of fishery production, in particular to a traditional Chinese medicine composition for freshwater shrimp feed. Background technique [0002] Freshwater shrimp is a kind of freshwater shrimp that people like to eat very much. The scientific name of freshwater shrimp is Macrobrachium japonicus. It is mainly distributed in the freshwater waters of China and Japan. It has the advantages of being on the market all the year round. Its living habits have the following characteristics: [0003] 1. Macrobrachium is an omnivorous aquatic animal, partial eclipse animal feed, artificial breeding is mainly fed with commercial pellet feed, its optimum growth water temperature is 18-30 ℃, when the water temperature drops to 4 ℃, it enters the overwintering period, when the water temperature When the temperature rises above 10°C, the vitality will increase, and the food intake will gradually increase. [0004] 2. The freshwater shr...

[0006] 4. The freshwater prawns are backlit. They hide in the dark during the day and come out to move at night. However, during the reproductive season, they come out for mating activities during the day. When feeding artificially, they also come out to fight for food during the day.

[0017] As the number of freshwater prawns in natural waters is getting smaller and smaller, artificially cultured freshwater prawns have become the main source of freshwater prawns. During the artificial cultivation of freshwater prawns, due to factors such as increased density of freshwater prawns, small available space, and uneven nutrient supply of feed, there will be The phenomenon of low food intake, low survival rate and small weight gain of freshwater shrimp reduces the effect of freshwater shrimp farming
