High-efficiency and environment-friendly puffed compound feed for snakehead fishes

Abstract

The invention relates to a high-efficiency and environment-friendly puffed compound feed for snakehead fishes, which is prepared from the following raw materials in percentage by weight: 23-50 of imported steam fish meal, 5-15 of biological fish meal ABP600, 5-10 of soybean meal, 3-8 of cottonseed meal, 3-8 of rapeseed meal, 3-10 of meat and bone meal, 2-5 of squid visceral meal, 25-40 of high protein flour, 1.0-3.0 of blood meal, 1.0-3.0 of soybean lecithin, 2.0-5.0 of marine fish oil, 0.2-1.0 of choline chloride (50%), 0.05-0.3 of vitamin C-phosphate (35%), 0.3-1.5 of calcium biphosphate, 0.2-0.5 of complex multi-dimensional material, 0.5-1.5 of complex mineral salt, 0.1-0.3 of food attractant, 0.1-0.3 of microbial ecological agent, 0.03-0.08kg of A3a peptidoglycan, 0.01-0.04 of phytase and 0.04-0.08 of non-starch polysaccharide enzyme. The high-efficiency and environment-friendly puffed compound feed for snakehead fishes can meet complete nutrient requirements for high-density culture of snakehead fishes, enables the cultured fishes to grow quickly, has a feed coefficient between 0.9 and 1.2, and has the advantages of high feed conversion rate, obvious culture benefit, good energy of cultured fishes, high survival rate and long-distance transport resistance. Compared with the snakehead fishes cultured by other feeds, the snakehead fishes cultured by the feed of the invention have the advantages that the discharge rate of nitrogen and phosphorus can be reduced by 8%-15%, and the pollution to culture water is little.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to a high-efficiency and environment-friendly puffed compound feed for snakehead fish. Background technique [0002] Channaidae is a freshwater rare and valuable farmed fish with strong vitality. Because of its short breeding cycle, delicious taste, and high-density breeding, it is widely cultured in the coastal provinces of southern my country. However, there are currently few international and domestic studies on the extruded compound feed for Channaidae fish. The compound feed used in artificial breeding has a high coefficient and is expensive, resulting in a substantial increase in breeding costs. When the breeding price falls, the feed cost may be higher than Its market price; due to insufficient research on the nutrition of Channaidae fish, excessive nitrogen and phosphorus discharge in the feed has seriously polluted the aquaculture water and increased the risk of aquaculture;...

Problems solved by technology

However, there are few international and domestic studies on extruded compound feeds for Channaidae fish. The compound feeds used in artificial breeding have a high coefficient and are expensive, resulting in a substantial increase in breeding costs. When the breeding price declines, the feed cost may be higher than Its market price; due to the current insufficient research on the nutrition of Channaidae fish, the excessive nitrogen and phosphorus discharge in the feed has seriously polluted the aquaculture water and increased the risk of aquaculture; at the same time, due to high-density intensive aquaculture, the fish body The immune function and anti-stress ability are reduced, and the survival rate of breeding is not high

The above reasons have seriously hindered the further development of the fish aquaculture industry of Channaidae
