Shelling and growth-promoting Chinese herbal medicine composite feedstuff additive used for penaeus vannamei

Abstract

The invention discloses a shelling and growth-promoting Chinese herbal medicine composite feedstuff additive used for penaeus vannamei. The feedstuff additive provided by the invention comprises Chinese herbal medicine components of longleaf garden burnet root, giant knotweed rhizome, common monkshood daughter root and the like, and vitamins, phospholipid powder and calcium lactate. The feedstuff additive provided by the invention is green, safe, and environment-friendly. The feedstuff additive assists in promoting penaeus vannamei shelling, and improving breeding survival rate. The feedstuff additive can be used for replacing animal raw materials with increasingly short supplies. Therefore, penaeus vannamei industry development requirements can be satisfied.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a Chinese herbal medicine compound feed additive for shelling and growth promoting of Penaeus vannamei. Background technique [0002] Penaeus vannamei belongs to the family Penaeus, the genus Penaeus, and the subgenus Penaeus vannamei, also known as Penaeus vannamei, Litopenaeus vannamei, etc. prawns, Penaeus vannamei and Penaeus sinensis). Compared with other domestic cultured prawns, it has the advantages of fast growth, wide range of salinity adaptation, strong disease resistance, and high meat content. Since it was introduced into my country in 1988, it has rapidly spread throughout the country. At present, it is the prawn species with the largest prawn farming area and the highest yield in my country. Data from the 2010 National Fishery Economic Bulletin show that in 2010, the output of shrimp farming was 1.5447 million tons, of which 615,000 tons were Penaeus vannamei. [0...

Problems solved by technology

In the artificial high-density breeding environment, it is required to add shelling-promoting raw materials in the compound feed, otherwise there will be slow growth, unsuccessful shelling, low survival rate, and high feed coefficient.

At present, feed production enterprises usually add shrimp shell powder, shrimp meal, fish meal, etc. to meet the nutritional needs of prawns to promote shelling. Some feed manufacturers add antibiotics or even hormone drugs when producing prawn feed to achieve the expected effect of promoting molting. Development has caused many negative impacts, which is not conducive to the sustainable development of the shrimp industry, and it has also brought great hidden dangers to food safety

However, feed materials such as shrimp shell meal, shrimp meal, and fish meal are all processed products or by-products of deep-sea pelagic fisheries, but predatory fishing has led to partial desertification of marine fishery resources
