Slowly-sinking puffed compound feed for misgurnus anguillicaudatus and production process thereof

Abstract

The invention relates to slowly-sinking puffed compound feed for misgurnus anguillicaudatus and a production process thereof, and belongs to the technical field of misgurnus anguillicaudatus feed. The feed comprises 5-10 parts of fish meal, 3-10 parts of pork meal, 10-25 parts of bean meal, 3-8 parts of peanut meal, 5-15 parts of cottonseed meal, 5-20 parts of rapeseed meal, 3-10 parts of corn DDGS, 5-15 parts of rice bran, 15-20 parts of flour, 2-4 parts of soybean oil, 1-3 parts of monocalcium phosphate, 2-5 parts of bentonite, 0.2-1.5 parts of vitamin premix, 1-3 parts of microelement premix, 0.05-0.5 part of choline chloride, 0.05-0.1 part of antioxidant and 0.05-0.1 part of mould inhibitor. The utilization rate of the slowly-sinking puffed compound feed is increased for the misgurnus anguillicaudatus, healthy growth of the misgurnus anguillicaudatus is promoted, and pollution of remnant feed and metabolic waste to aquatic water is reduced. The volume weight of the produced slowly-sinking puffed compound feed is kept between that of granular feed and that of puffed feed, the feed has the characteristic of sinking slowly in water like the granular feed and further has the advantage of being long in water resisting time like the puffed feed, and therefore the feed meets the feeding characteristics of misgurnus anguillicaudatus.

Description

technical field [0001] The invention relates to a loach feed and a production process thereof. More specifically, the invention relates to a loach slow-settling extruded compound feed and a production process thereof, belonging to the technical field of loach feed. technical background [0002] loach( Misgurnus anguillicaudatus ) belongs to Cyprinidae ( Cy. priniforfes ), Loachidae ( Cobitidae ), the loach genus, commonly known as soil loach, true loach, etc. Loach likes to inhabit the bottom of still water. The living water temperature is 10-30°C, and the optimum water temperature is 25-27°C. It is a warm-water fish. When the water temperature is as high as 30°C, the loach dives into the mud to spend the summer, and when the water temperature drops below 5°C in winter, it drills into the mud at a depth of 20-30cm to survive the winter. Loach is widely distributed, with tender meat, delicious taste and rich nutrition, and is deeply loved by the public. Loach is a bott...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims to solve the problem that the existing loach sinking extruded compound feed is difficult to meet the most suitable loach growth requirements, and the growth rate of loach is relatively slow, and provides a loach slow sinking extruded compound feed, which has a reasonable ratio of raw material ratios , can meet the needs of the most suitable for the growth of loach, and improve the growth rate of loach
