Efficient environment-friendly black carp extrusion compound feed and production method thereof

Abstract

The invention discloses an efficient environmental-friendly black carp extrusion compound feed and a production method thereof. The method is characterized by comprising the following steps: mixing large amounts of other raw materials such as fish meal, extruded-soybean, soybean meal, rapeseed meal, cottonseed meal, wheat and rice bran and then coarsely crushing a mixture; adding spray-dried animal blood cells, larvae powder, monocalcium phosphate, choline chloride and salt for evenly mixing, carrying out superfine crushing; adding vitamin premis, mineral premix, rheum emodin, L-carnitine and allicin for evenly mixing; and carrying out steam tempering, extrusion, granulation, drying, spraying, cooling and the like on the mixed materials to obtain the product. The black carp extrusion compound feed is simple to prepare and has comprehensive and balanced nutrition, the digestibility of the black carp on feed nutrient substances can be improved, the feed coefficient is reduced, and the nitrogen and phosphorus emission is lowered. The feed has good palatability, excellent stability in water, and less feed wastes and water pollution. The feed can increase the immunity, antioxidation and anti-stress capabilities of the black carp, and promotes the growth of the black carp.

Description

technical field [0001] The invention relates to an aquatic compound feed and a production method thereof, in particular to a herring puffed compound feed and a production method thereof. Background technique [0002] Herring (Mylopharyngodon piceus Richardson), also known as green carp, black carp, black carp, snail green carp, and green root carp, is one of the "four major fish" in traditional freshwater farming in my country. Its individual is large, grows rapidly, the meat is tender and tender, the taste is delicious, and the nutritional value is high. It is welcomed by the majority of farmers and consumers. Herring generally lives in the middle and lower layers of the water body, and is a mild carnivorous fish. The wild herring feeds on zooplankton in the juvenile stage, and the adult fish mainly eat natural bait shellfish (snails, yellow clams, etc.). In the research of artificial compound feed, the requirements of herring for major nutrients have been basically ascert...

AI Technical Summary

Problems solved by technology

At present, farmers mainly use hard pellet feed to feed herring, and the feed coefficient is generally high. This is mainly because the content and ratio of various nutrients in the feed are unreasonable, resulting in the low utilization rate of herring for the nutritional components of the feed, and excreting a large amount of environmental pollution. Unfavorable pollutants such as ammonia nitrogen and phosphorus

In addition, the water stability of these feeds is poor, and the dissolution rate in water remains high.

In addition, the stocking density is too high and a large amount of feeding, etc., a large amount of unused feed enters the water body, which not only causes a waste of feed resources, but also leads to eutrophication of the aquaculture water body, damage to the ecological balance of the water body, deterioration of water quality, and poor water quality. Environmental stress will lead to immunosuppression of farmed fish, stunted growth, increased susceptibility to pathogenic microorganisms, breeding of diseases, and decreased breeding efficiency, which seriously restricts the healthy and sustainable development of herring farming industry
