Liver and gall bladder protection type puffed compound feed for crucians and preparation method thereof

Abstract

The invention discloses a liver and gall bladder protection type puffed compound feed for crucians, aiming at providing a puffed compound feed which is environmentally friendly, nutritional and efficient and can protect liver and gall bladder and intestinal health of the crucians. The liver and gall bladder protection type puffed compound feed is prepared from the following raw materials by weight percent: 5-10% of fish meal, 5-25% of bean pulp, 4-9% of peanut meal, 5-15% of rapeseed meal, 4-10% of cottonseed meal, 5-10% of pork powder, 5-12% of corn DDGS (distillers dried grains with soluble), 7-13% of rice bran, 5-20% of flour, 3-15% of wheat, 1-3% of soyabean lecithin oil, 1-3% of soybean oil, 1.0-3.0% of monocalcium phosphate, 0.1-1.0% of vitamin premix, 1-3% of trace mineral premix, 0.1-0.8% of L-Ascorbate-2-Phosphate, 0.1-1.0% of choline chloride, 0.01-0.1% of antioxidant, 0.01-0.1% of mildew preventive, and the sum of the weight percentages of all components is 100%. The liver and gall bladder protection type puffed compound feed belongs to the technical field of fish feed.

Description

technical field [0001] The invention relates to an extruded crucian carp compound feed, in particular to a healthy, high-efficiency, liver-protecting and gallbladder-protecting crucian carp extruded compound feed, which belongs to the technical field of fish feed. Background technique [0002] Crucian carp belongs to Cyprinidae, omnivorous, bottom-dwelling fish, widely distributed, and has strong adaptability to water temperature, salinity, dissolved oxygen, pH value, etc. The optimum growth water temperature is 25-30°C. Respiration) is relatively developed, and can survive normally when the dissolved oxygen is reduced to 0.3 mg / L. [0003] Juvenile crucian carp mainly feed on zooplankton, such as rotifers, cladepods, copepods, etc., and adult fish mainly feed on artificial compound feed. The aquaculture volume of crucian carp is increasing year by year. According to statistics in 2010, the aquaculture output of crucian carp in my country is 2.216 million tons, ranking four...

Problems solved by technology

[0007] Although the extruded material has great advantages compared with the granular material, there are also some shortcomings in the extruded material for crucian carp. The extruded material has a good absorption effect. "Tofu dregs liver"; it is also easy to cause crucian carp enteritis; in addition, crucian carp cultured with puffed material has poor anti-stress ability, poor resistance, and intolerance to transportation, etc.
