Compound feed for healthy aquaculture of grass carps in large water area and production method thereof

Abstract

The invention discloses a compound feed for healthy aquaculture of grass carps in a large water area and a production method thereof. The compound feed is compounded from the following raw materials in parts by weight: 10-20 parts of bean cakes, 15-25 parts of rapeseed cakes, 10-20 parts of cotton cakes, 10-19 parts of wheat bran, 10-15 parts of wheat middling, 10-20 parts of rice bran, 3-6 parts of shell powder, 5-10 parts of wheat meal, 4-8 parts of straw powder, 0.1-0.2 part of southernwood powder, 0.01-0.05 part of dried medlar powder, 0.1-0.2 part of vitamin b complex, 10-20 parts of liquid lactobacillus, 20-40 parts of water, 0.1-0.5 part of salt and the like. The compound feed has the advantages that 1, the nutritional ingredients and mineral substances of the pellet feed are rich and replace the original fish meal, so that the cost is reduced, an animal albumen source is obtained, and the absorption utilization ratio is high; 2, the meat quality of the grass carps is improved, the growth rate of the grass carps after eating the feed can be improved by more than 8%, the production cost of a grass carp feed is reduced by more than 5%, and the culture cost of the grass carps is reduced by more than 10%; and 3, the immunologic function of the grass carps is improved, the capabilities of preventing diseases, curing diseases and resisting viruses of the grass carps are enhanced, and the recapture rate of the grass carps can be improved by 5%.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a compound feed for healthy grass carp aquaculture in a large water surface and a production method thereof. Background technique [0002] Grass carp is the largest main species in my country, accounting for 20% of freshwater fish production, and it is also a freshwater fish species that people often eat and love. Grass carp meat is tender and tender, with few bony spurs and rich nutrition. Every 100 grams of grass carp meat contains 17.9 grams of protein, 4.3 grams of fat, multivitamins, and rich unsaturated fatty acids, which are good for blood circulation and are good for cardiovascular patients. good food. However, grass carp is also the most disease-prone, and the outbreak of grass carp disease often brings a devastating blow to the farming in some areas. [0003] At present, the competition in grass carp farming mainly lies in the cost of feed and the survival ra...

Problems solved by technology

On the one hand, due to the increase in world food prices, the feed cost of grass carp farming is also increasing; on the other hand, the existing compound feeds are not mainly aimed at improving the immunity of grass carp, and cannot greatly reduce the loss of fish death. Households have used antibiotics to reduce the prevalence of grass carp, but the residues of antibiotics will cause great harm to the human body
