Chinese medicinal herb disease-resistant additive for prawn feed

Abstract

The invention discloses a Chinese medicinal herb disease-resistant additive for a prawn feed. The additive is prepared from the following raw materials in parts by weight: 20-30 parts of indigowoad root, 10-20 parts of parslane herb, 10-20 parts of dangshen, 10-20 parts of garlic, 10-15 parts of baical skullcap root, 10-15 parts of largehead atractylodes rhizome, 10-15 parts of Chinese pulsatilla root and 8-12 parts of dried orange peel. The additive is prepared by the following steps of: grinding the Chinese medicinal herbs into fine powder of 100 meshes; and mixing uniformly. The invention has the advantages: (1) the adding amount of the feed additive in a prawn compound feed is only 0.15-0.25 percent, and the additive can be fed after being mixed with the feed in the weight ratio 1:500 before feeding; (2) the immunity and disease resistance of prawns can be enhanced remarkably, the survival rate is increased, a good disease resistance effect on intestinal tract diseases such as prawn enteritis and the like is particularly achieved, and intestinal mucosa injury is repaired; (3) the additive does not cause any adverse effect on the palatability of the prawn compound feed; and (4) raw materials adopted for the additive have rich sources in China and stable and low prices, and the production and processing processes are simple.

Description

technical field [0001] The invention relates to an aquatic feed additive, in particular to a Chinese herbal medicinal prawn feed disease resistance additive. Background technique [0002] In recent years, my country's shrimp farming industry has developed rapidly. In 2010, the total output of shrimp farming in China was 1.348 million tons, accounting for 38.5% of the world's total farming output of 3.5 million tons. It has become the country with the largest shrimp farming output. With the expansion of the scale of shrimp farming, many different farming models have emerged, but due to the pursuit of yield and economic benefits, high-yield and high-density farming still dominates. While this high-density culture greatly increases the yield of prawns, it also brings greater pollution to the culture water body and water environment, resulting in frequent occurrence of diseases during the culture process. In order to cope with the disease, it is inevitable to increase the amoun...

Problems solved by technology

However, because the mechanism of traditional Chinese medicine and the water environment are very complicated, the application research in aquatic animals is lack of systematic, so the Chinese herbal medicine additives used in aquatic animals still have many deficiencies, for example, some additives have more complex composition, materials and processing are more complicated. Troublesome, some have poor stability in water, and the amount added to the feed is too high, which increases the cost, is not conducive to application and promotion, and some also affects the palatability of the feed
