Environmental-friendly carassius auratus low-protein high-fat compound feed

Abstract

The invention relates to the technical field of feeds, in particular to an environmental-friendly carassius auratus low-protein high-fat compound feed. The feed consists of the following raw materialsin percentage by content: 8.0-10.0% of chicken meat powder, 1.0-4.0% of fish soluble extracts, 5.0-8.0% of soybean meal, 3.0-5.0% of fermented soybean meal, 9.0-10.0% of cottonseed meal, 9.0-12.0% ofrapeseed meal, 10.0-20.0% of DDGS, 3.0-5.0% of corn germ meal, 9.0-10.0% of flour, 10.0-20.0% of middling, 2.5-5.0% of zeolite powder, 1.4-2.0% of calcium dihydrogen phosphate, 3.0-6.0% of soybean oil, 0.6-1.0% of phosphatide oil, 1.6-2.0% of Chinese prickly ash seeds, 0.15-0.2% of a vitamin premix feed, 0.20-0.40% of lysine sulphate, 0.05-0.15% of methionine, 0.05-0.15% of threonine, 0.02-0.03%of bile acid, 0.01-0.02% of L-carnitine, 0.05-0.1% of a mildewproof agent, 0.01-0.04% of an antioxidant and the balance of composite trace elements. According to the feed disclosed by the invention, fish meal is not added, the complementary properties of amino acids between animal and plant protein sources are utilized, and crystal amino acids are added for balancing the amino acid composition ofthe feed, so that the protein level of the feed is reduced, and the fat level of the feed is increased; the bile acid, the carnitine and the like are added, so that the digestion and utilization capacity of fat by carassius auratus can be increased, the protein saving efficiency of the fat is exerted, the proteinosis rate can be obviously increased, and the discharge of nitrogenous waste can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to an environment-friendly low-egg and high-fat compound feed for crucian carp. Background technique [0002] Crucian carp (Carassius auratus) belongs to the genus Carassius auratus of the genus Cyprinidae of the order Cyprinidae. According to the 2016 Fishery Statistical Yearbook, the national production of crucian carp in 2015 was as high as 2.912 million tons, ranking third among freshwater feeding fish species. At present, the mainstream commodity crucian carp pellet feed in the market has a fishmeal content of about 6-12%, a protein level of 30-36%, a fat level of 6-8%, and a generally low protein deposition rate of about 20-25%. With the continuous development of the aquaculture industry, the shortage of fishmeal resources will become more and more serious. How to reduce or even eliminate the use of fishmeal in feed has become a major issue for the sustainable development of the ...

Problems solved by technology

With the continuous development of the aquaculture industry, the shortage of fishmeal resources will become more and more serious. How to reduce or even eliminate the use of fishmeal in feed has become a major issue for the sustainable development of the feed industry. In addition, the high protein level in crucian carp feed And low protein deposition rate, resulting in a large amount of nitrogen-containing waste discharged into the water, resulting in eutrophication of aquaculture water, blue-green algae outbreaks, increasing the difficulty of water quality management and the probability of fish disease
