Chinese herbal medicine feed additive for prawns

Abstract

The invention discloses a Chinese herbal medicine feed additive for prawns. The Chinese herbal medicine feed additive comprises the following components in parts by weight: 20-30 parts of isatis root, 15-25 parts of dangshen, 10-15 parts of angelica sinensis, 5-15 parts of herba andrographitis, 15-25 parts of astragalus membranaceus and 10-20 parts of radix scutellariae. The Chinese herbal medicine feed additive for prawns is uniformly added to a common feed for prawns according to the proportion of 0.1-0.5%, is mixed with the common feed and then is fed. The Chinese herbal medicine feed additive is scientific in compatibility, high in stability in water and good in palatability, and is capable of remarkably enhancing the immunity of the organism and the disease resistance of prawns, increasing the survival rate of prawns and reducing the feeding cost of prawns.

Description

technical field [0001] The invention relates to an aquatic feed additive, and mainly relates to a Chinese herbal medicine feed additive for prawns. Background technique [0002] In recent years, my country's prawn farming industry has developed rapidly. In 2012, the total output of prawn farming in China was 1.53 million tons, accounting for about 1 / 3 of the global total. It is the largest prawn farming country in the world. With the development of the modernization and intensification of the shrimp farming industry, the high-density farming model makes the ecosystem structure of the farming environment single and weak in resistance, which can easily lead to deterioration of water quality and frequent occurrence of shrimp diseases. In response to diseases, people use a lot of chemicals and antibiotics. However, the negative effects of these drugs are also very obvious, not only changing the normal composition of the intestinal flora of prawns, leading to the imbalance of the...

With the development of modernization and intensification of the shrimp farming industry, the high-density farming model makes the ecosystem structure of the farming environment single and weak in resistance, which can easily lead to deterioration of water quality and frequent occurrence of shrimp diseases

In response to diseases, people use a lot of chemicals and antibiotics. However, the negative effects of these drugs are also very obvious, not only changing the normal composition of the intestinal flora of prawns, leading to the imbalance of the micro-ecological environment in the intestinal tract, but also making the drugs in the biological environment. Residues in the body hinder the healthy development of the pollution-free aquaculture industry

[0003] There have been many reports on the application of Chinese herbal medicine feed additives in prawn feed at home and abroad. However, due to the lack of systematicness in the current research, they often refer to the formulas of terrestrial animals, and do not use the principles of Chinese pharmacy, pharmacy, and pharmacology to target them. Research on relatively low-level aquatic animals, and rarely consider the synergistic or antagonistic effects between the components, so the current Chinese herbal feed additives for prawns still have many deficiencies, such as relatively complex composition, poor stability in water, and poor stability in water. If the amount added to the feed is too high, it not only increases the cost, but also is not conducive to the application and promotion, and some also affect the palatability of the feed
