Environmental-friendly mixed culture fish feed capable of strengthening food calling properties and preparation method of environmental-friendly mixed culture fish feed

Abstract

The invention discloses an environmental-friendly mixed culture fish feed capable of strengthening food calling properties. The environmental-friendly mixed culture fish feed is prepared from the following raw materials in percentage by weight: 10-15% of soybean meal, 15-30% of rape seed cakes, 5-15% of cottonseed meal, 2-10% of corn alcohol meal, 2-8% of pig internal organ powder, 2-8% of fish meal, 2-5% of beer yeast powder, 5-15% of high-gluten flour, 1-4% of soybean oil, 0.5-1% of soybean phospholipid oil, 2-5% of calcium dihydrogen phosphate, 2-5% of bentonite, 0.5-1% of bacillus subtilis, 0.2-0.5% of taurine, 0.3-0.6% of dried orange peel, 0.05-0.1% of sulfobetaine, 0.1-0.5% of choline chloride, 0.05-0.2% of methionine, 0.2-0.5% of lysine, 0.2-0.6% of composite trace elements and 0.3-0.4% of composite vitamins. The feed can improve the food calling properties and the digestibility, reduce the powder, and reduce the waste of feeds.

Description

technical field [0001] The invention relates to an environment-friendly polyculture fish feed with enhanced food-attractiveness and a preparation method thereof. Background technique [0002] In recent years, China's freshwater aquaculture industry has changed from long-term shortage to sufficient supply, and the output of major products is in the leading position in the world. Grass carp, silver carp, bighead carp, carp, crucian carp, bream, and herring are the main bulk freshwater fish cultured species in my country, and they are also the main body of freshwater aquaculture output, and their industrial status is very important. Freshwater aquatic products not only meet the needs of the people to consume high-quality animal protein, but also improve the nutritional level of the people. The aquaculture and freshwater aquaculture industry has gradually changed from a sideline industry to a leading industry, providing a way for farmers engaged in freshwater aquaculture to make...

Problems solved by technology

[0004] In view of the above technical problems, the present invention provides an environmentally friendly polyculture fish feed with enhanced food-attractiveness and a preparation method thereof. The polyculture fish pellet feed has poor food-attractiveness, low digestion utilization rate, and poor stability in water. It is easy to cause water pollution and other problems. It not only improves the raw material composition of the mixed fish feed formula, adds food-attracting factors, but also finely pulverizes and granulates the feed materials, which improves the food-causing and digestibility of the feed, reduces powder, and reduces feed. waste
