Puffing compound feed suitable for mandarin fish feeding and nutrition and preparation method of puffing compound feed

Abstract

The invention discloses puffing compound feed suitable for mandarin fish feeding and nutrition and a preparation method of the puffing compound feed. The puffing compound feed is prepared from the following components in percentage by mass: 10-12% of wheat flour, 50-55% of gadus powder, 3-5% of shrimp powder, 3-8% of chicken powder, 1-3% of hemoglobin powder, 5-10% of soybean meal, 2-3% of sleeve-fish paste, 1-2% of fish oil, 2-3% of soybean oil, 0.5-1.5% of soybean phospholipid oil, 1-2% of calcium dihydrogen phosphate, 0.2-0.5% of choline chloride (50%), 1-2% of composite premix and 1-3% ofbentonite. The invention further relates to a preparation method for the mandarin fish puffing compound feed suitable for mandarin fish feeding habits. The puffing compound feed is mainly animal protein, and is in a long-strip shape and of slow sinking, and the puffing compound feed meets the carnivorous predatory fish feeding and nutritional requirements of the mandarin fish. The mandarin fish feed conforms a breeding model which can replace live fish or chilled fish, and has the advantages of saving land resources, saving water resources, saving labor, being environment-friendly and the like.

Description

technical field [0001] The invention belongs to the field of aquaculture and relates to the technology of full-price compound feed for mandarin fish, in particular to an expanded compound feed suitable for mandarin fish feeding and nutrition and a preparation method thereof. Background technique [0002] Mandarin fish is commonly known as mandarin fish and sweet-scented osmanthus fish. Its meat is tender and easy to digest. It has been a valuable freshwater fish in my country since ancient times. Since the successful artificial breeding of mandarin fish in 1974, its breeding scale has expanded rapidly. In 2016, the national production of mandarin fish exceeded 300,000 tons, and the breeding provinces involved 23 provinces, of which 7 provinces exceeded 10,000 tons, and Guangdong Province exceeded 90,000 tons. Mandarin fish aquaculture has developed into one of the important pillar industries of freshwater aquaculture, with great economic benefits and growth potential. [00...

AI Technical Summary

Problems solved by technology

[0003] In the natural state, mandarin fish mainly feed on live bait. At present, most of the cultured mandarin fish mainly feed on live bait, which not only brings inconvenience to production management, increases the cost of breeding, but also affects land and water resources. waste of

In recent years, breakthroughs have been made in mandarin fish domestication technology, which has basically solved the technical problems of mandarin fish feeding feed, but there are still a series of problems caused by the existing feed that cannot meet the nutritional needs and feeding habits of mandarin fish, such as low domestication rate and different specifications. Neatness, cannibalism, liver disease, etc.
