A kind of prawn biological feed and its application

Abstract

The invention belongs to the technical field of aquaculture feed and biological engineering, and particularly relates to a novel biological feed for prawn and application thereof. The feed is a dry feed comprising the following components: by weight, 10 ~ 15% of fermented soybean meal, 15 ~ 25% of fermented raw meal, 15 ~ 20% of enzymolysis polypeptide, 5 ~ 7% of wall breaking yeast, 5% ~ 7% of fish meal, 3 %~ 5% of shrimp shell powder, 20% ~ 25% of bread flour, 1 ~ 2% of soybean phospholipids, 1 ~ 2% of calcium dihydrogen phosphate, 0.5 ~ 1% of compound vitamins and 0.5-1% of compound minerals. The novel biological feed uses small biological enzymolysis peptide, fermented plant proteins and the wall breaking yeast as main protein sources for production of low fish meal formula feed, the fish meal use amount of the biological feed for the prawn can be significantly reduced, the feed efficiency and utilization rate can be improved, resources can be effectively saved, environmental and water pollution can be reduced, animal immune resistance to diseases can be enhanced, and long term feeding experiment results show that the low protein feed for the prawn is used for feeding litopenaeus vannamei, has no adverse effects on the growth performance and feed coefficient, and can reduce nitrogen and phosphorus emissions in water.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed and bioengineering, in particular to a novel prawn biological feed and its application. Background technique [0002] The intensive breeding mode puts forward high requirements on the breeding density and breeding technology of aquatic animals. Under high-density farming conditions, the growth of aquatic animals is slow, the quality declines, and the incidence and mortality increase. At present, the prevention and treatment of many aquatic animal diseases depends on the use of antibiotics and chemical drugs, and long-term use of antibiotics and chemical drugs will make pathogenic bacteria resistant to drugs, and the efficacy of drugs will also be reduced; and antibiotics and chemical drugs are likely to cause aquaculture water pollution. pollution and damage to the ecological environment, drug residues in some aquatic animals will also pose a threat to human food safety. As a new type of gre...
