Environment-friendly macrobrachium rosenbergii functional compound feed

Abstract

The invention relates to an environment-friendly macrobrachium rosenbergii functional compound feed as well as a preparation method and application thereof, and belongs to the technical field of aquaculture feeds. The feed comprises the following components in percentage by weight: 2%-4% of fermented soybean meal, 6%-10% of cottonseed meal, 6%-12% of rice protein powder, 5%-12% of hydrolyzed chicken hemoglobin, 14%-20% of chlorella, 8%-16% of spirulina, 3%-8% of tenebrio molitor protein, 3.8%-4.8% of sunflower meal, 4%-6% of enzymolysis fish soluble powder, 1.5%-2% of hermetia illucens powder, 0.9%-1.1% of rapeseed oil, 1% of schizochytrium limacinum powder, 0.9%-1.1% of lysolecithin and the balance of water. The feed comprises the following components in percentage by weight: 14-16% of wheat, 4-6% of kelp powder, 1.5% of monocalcium phosphate, 0.6-0.8% of vitamin premix and 0.9-1.1% of mineral premix. The feed is balanced in nutritional value, the breeding effect is not obviously different from that of a feed with normal fish meal and soybean meal content, but the feed remarkably reduces emission of nitrogen and phosphorus in the breeding process of macrobrachium rosenbergii, is a low-carbon and green functional feed product, and can effectively improve economic benefits and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to an environment-friendly functional compound feed for Macrobrachium rosenbergii. Background technique [0002] Macrobrachium rosenbergii (Macrobrachium rosenbergii) is a large freshwater prawn native to Southeast Asia. It has a wide range of food habits, fast growth, rich nutrition, and short breeding cycle; it likes weak alkaline water quality, the optimum pH range is 7.6-8.6, and the optimum growth water temperature It is 24-30°C. In 2020, the annual output of Macrobrachium rosenbergii in my country will reach about 160,000 tons, of which Guangdong, the main producing province of Macrobrachium rosenbergii, will have about 69,000 tons, Jiangsu about 55,000 tons, and Zhejiang about 26,000 tons. [0003] At present, the main protein source in the feed of Macrobrachium rosenbergii is still conventional raw materials such as fish meal and oilseed meal, and there is a lack o...

Problems solved by technology

However, the supply of raw materials such as fishmeal is insufficient, and the price has soared, leading to high feed costs and a sharp drop in corporate profits; Pollution control itself consumes energy, and the carbon emissions of sewage treatment in my country account for about 2% to 5% of the carbon emissions of the whole society; in addition, the dependence on feed materials such as soybeans and corn, which are traded globally, greatly increases the risk of carbon emissions
