Embodiment 1

[0027] Feed by weight percentage: fermented soybean meal 15%, fermented raw meal 18%, enzymatic peptide 20%, broken yeast 7%, fish meal 7%, shrimp shell powder 5%, high-gluten flour 22%, soybean lecithin 2% , calcium dihydrogen phosphate 2%, multivitamin 1%, and multimineral 1%.

[0028] The fermented soybean meal is vegetable protein fermented by compound probiotics. Screen Bacillus subtilis and Candida utilis with higher protease activity and mix them in soybean meal for fermentation. It uses microbial mixed solid-state fermentation technology to prepare fermented vegetable protein, eliminates anti-nutritional factors in soybean meal to the greatest extent through microbial fermentation, effectively degrades proteins with larger molecular weights into high-quality small peptide protein sources, and can produce probiotics, Active substances such as small peptides, lactic acid, and UGF (unknown growth factor) become protein raw materials with nutritional and probiotic propert...

Embodiment 2

[0040] The medium-term dry powder biological feed for prawns, by weight percentage, fermented soybean meal 15%, fermented raw meal 20%, enzymatic peptide 18%, broken yeast 7%, fish meal 6%, shrimp shell powder 5%, high-gluten flour 25% ﹪, soybean lecithin 1.5%, calcium dihydrogen phosphate 1.5%, multivitamin 0.5%, and multimineral 0.5%.

[0041] Wherein, the concrete composition of compound vitamin and compound mineral is identical with embodiment 1.

Embodiment 3

[0043] Dry powder biological feed for prawns in the later stage of growth, by weight percentage, fermented soybean meal 15%, fermented raw meal 25%, enzymatic polypeptide 15%, broken yeast 5%, fish meal 5%, shrimp shell powder 5%, high-gluten flour 25% ﹪, soybean lecithin 1﹪, calcium dihydrogen phosphate 1﹪, multivitamin 0.5﹪, compound mineral 0.5﹪.

[0044] Wherein, the concrete composition of compound vitamin and compound mineral is identical with embodiment 1.

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...
