A compound feed for growing Penaeus vannamei in greenhouses

Abstract

The invention relates to a compound feed for breeding penaeus vannamei boone in a greenhouse. The compound feed is characterized by comprising the following specific components by weight percent: 28%-45% of imported steam fish meal, 15%-35% of bean pulp, 4%-8% of peanut meal, 3%-9% of insect protein powder, 2%-6% of vital gluten, 21%-25% of flour, 2%-4% of fish soluble condensate, 1%-4% of fish oil, 2%-4% of phospholipid oil, 2.0%-4.0% of calcium dihydrogen phosphate, 0.01%-0.04% of protease, 0.01%-0.04% of probiotics, 0.1%-0.2% of beta-glucan, 0.2%-0.4% of methionine and the balance being additives including composite vitamin, composite mineral, Vc phosphate, choline chloride, sodium chloride, a mildew preventive, an antioxidant and the like, and the total percent is 100%.

Description

technical field [0001] The invention relates to a shrimp compound feed, in particular to a greenhouse cultured Penaeus vannamei compound feed, which belongs to the technical field of feed. Background technique [0002] Penaeus vannamei belongs to Decapod order, Penaeidae, and Penaeus genus. Its scientific name is Litopenaeus vannamei. It is a wide-temperature and wide-halt tropical shrimp. The meat of Penaeus vannamei is delicious, and the processed meat rate can be as high as 67%. It has a wide temperature range and can grow at 18-32°C. It also has a wide salt range and can grow at a salinity of 1-40‰. It is an excellent desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. It has become the main cultured species of prawns in my country. Both domestic sales and exports are considered. The culture cycle of Penaeus vannamei is short, with high economic benefits and broad development prospects. In the coastal areas of Jiangsu, from Nant...

Problems solved by technology

However, at present, in order to one-sidedly pursue high production, shorten the breeding cycle, and advance the market time, farmers are one-sidedly pursuing high-protein feed, which leads to continuous improvement of the nutritional level of the feed, especially the continuous increase in the amount of imported fishmeal in the feed, and the continuous increase in the protein level of the feed. Residual bait and feces pollute the breeding water more and more seriously. The ammonia nitrogen and nitrous acid in the water body are difficult to control. Especially in the middle and later stages of breeding, there are many diseases, and even the whole army is wiped out. The risk of breeding is increasing. The conversion rate of feed is not high, and it needs to be continuously drained, which causes a great waste of water resources

Due to the continuous shortage of marine fishery resources, the supply of imported fish meal is very unstable, the price continues to rise, and the supply is limited. Domestic feed companies passively accept high-priced fish meal, which seriously threatens and restricts the sustainable development of the shrimp farming industry.

At the same time, due to the high density, a large number of feeds are fed intensively, the immunity of the shrimp body is low, and the incidence of various diseases remains high, which seriously restricts the healthy, stable and sustainable development of the Penaeus vannamei aquaculture industry in greenhouses.
