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
