Problems solved by technology

In the prior art, pig manure is generally used as fertilizer for planting and planting after retting. At present, there is no prior art that specifically uses pig manure for fish farming. If it is used for fish farming, the organic matter in pig manure will Untreated pig manure generally does not contain amino acids necessary for fish, especially lysine, methionine and tryptophan, which are difficult for fish to absorb, and the nutrient release rate is low. In order to ensure the nutrient supply of fish, the amount of pig manure generally put Larger, for stagnant water environment, it is easy to cause eutrophication of water body, and then a large number of organisms breed, water dissolved oxygen decreases, and fish growth is hindered. At the same time, due to the low absorption rate, pig manure cannot be added as the main nutrient component, and only 30% of the mass can be added at most Ratio, the other 70% mass ratio still needs to be supplemented with fish feed, so the feeding cost is still high

Abstract

The invention discloses a pig-manure-processed easy-to-absorb pollution-free fish feed and a production method thereof. In percentage by mass, the pig-manure-processed easy-to-absorb pollution-free fish feed contains 20-25% of proteolytic amino acids, and comprises at least 0.3% of lysine, 1.2% of methionine, 0.5% of tryptophan, 12-18% of fat-hydrolyzed carbohydrates, 12-18% of ash, 7-10% of carbohydrates, and nitrogen, phosphorus and potassium of which the total mass is 0.2-0.5%; and the pig-manure-processed easy-to-absorb pollution-free fish feed further comprises, in concentration by mass,3x10<6> cfu / g to 5X10<8> cfu / g of lactobacillus reuteri, 1x10<6> cfu / g to 2x10<8> cfu / g of aeromonas, 1x10<6> cfu / g to 2x10<8> cfu / g of bifidobacterium adolescentis, and 2x10<6> cfu / g to 3x10<8> cfu / gof bacillus licheniformis. The pig-manure-processed easy-to-absorb pollution-free fish feed is high in recovery rate, good in absorbability, capable of utilizing wastes and reasonable in nutrient proportion, and causes no water eutrophication.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a pig manure-treated and easily absorbed pollution-free fish feed and a manufacturing method thereof. Background technique [0002] Pig manure contains only 15% organic matter, of which protein accounts for about 10% of the total weight of manure. Pig manure is finer in texture and contains more organic matter and nitrogen, phosphorus and potassium nutrients. However, pig manure treatment is a key environmental protection technology, otherwise it will cause environmental pollution. In the prior art, pig manure is generally used as fertilizer for planting and planting after retting. At present, there is no prior art that specifically uses pig manure for fish farming. If it is used for fish farming, the organic matter in pig manure will Untreated pig manure generally does not contain amino acids necessary for fish, especially lysine, methionine and tryptophan, which are diff...
