specific Embodiment approach 1

[0016] Specific embodiment one: the Yadong salmon broodstock feed of the low protein amino acid balance of this embodiment, by weight parts by the secondary powder of 20~38 parts, the soybean protein concentrate of 5~20 parts, the fishmeal of 25~40 parts, 1~ 20 parts of fish oil, 1-20 parts of soybean oil, 0-3 parts of cellulose, 0.5-2 parts of calcium dihydrogen phosphate, 0.5-5 parts of squid paste, 0.5-3 parts of soybean lecithin, 0.02-0.05 parts ethoxyquinoline, 0.02 to 0.5 parts of arginine, 0.5 to 1 part of methionine, 0.02 to 0.5 parts of phenylalanine and 1 to 2 parts of a premix; wherein the premix is ​​in parts by weight The number is from 0.1 to 0.5 parts of Epimedium powder, 0.1 to 0.5 parts of Eucommia leaf powder, 0.01 to 0.02 parts of β-glucan, 0.01 to 0.02 parts of Bacillus coagulans, 0.05 to 0.1 parts of vitamin C, 0.005 parts ~0.01 part of vitamin E, 0.1~0.2 part of choline, 0.1~0.2 part of magnesium oxide, 0.01~0.1 part of zeolite powder, 0.0003~0.0005 part ...

specific Embodiment approach 2

[0020] Specific embodiment two: what this embodiment is different from specific embodiment one is that the Yadong salmon broodstock feed of low-protein amino acid balance, by weight the secondary powder of 28.23 parts, the soybean protein concentrate of 15 parts, the fish meal of 30 parts , 8.5 parts of fish oil, 10.5 parts of soybean oil, 2 parts of cellulose, 1.5 parts of calcium dihydrogen phosphate, 1 part of squid paste, 1 part of soybean lecithin, 0.04 parts of ethoxyquinoline, 0.03 parts of refined amino acid, 0.6 parts of methionine, 0.1 parts of phenylalanine and 1.5 parts of premix. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Specific embodiment three: what this embodiment is different from specific embodiment one is that the Yadong salmon broodstock feed of low-protein amino acid balance is by weight the secondary powder of 25.85 parts, the soybean protein concentrate of 18.69 parts, the fish meal of 35 parts , 7.3 parts of fish oil, 7.3 parts of soybean oil, 0.36 parts of cellulose, 0.8 parts of calcium dihydrogen phosphate, 1 part of squid paste, 2 parts of soybean lecithin, 0.05 parts of ethoxyquinoline, 0.02 parts of refined amino acid, 0.6 parts of methionine, 0.03 parts of phenylalanine and 1 part of premix. Others are the same as in the first embodiment.

Abstract

The invention discloses a salmo trutta fario linnaeus parent fish feed with low protein and amino acid balance, which belongs to the technical field of aquatic feed products, and can be used for solving the problems that no salmo trutta fario linnaeus feed exists and the protein conversion rate is low and the amino acid is unbalanced when a trout feed is used. The salmo trutta fario linnaeus parent fish feed comprises wheat middling, soybean protein concentrate, fish meal, fish oil, soybean soil, cellulose, calcium dihydrogen phoshate, inkfish paste, soyabean lecithin, ethoxyquin, arginine, methionine, phenylalanine and a premix. According to the salmo trutta fario linnaeus parent fish feed, the utilization rate of a feed raw material with lower digestibility of salmo trutta fario linnaeus is reduced, the quality of the salmo trutta fario linnaeus parent fish feed is easily controlled, the digestion utilization rate of the salmo trutta fario linnaeus parent fish feed is improved, a raw material source is stable, the cost is lowered, the problem of unbalanced amino acid of a conventional feed is overcome, the protein efficiency of the feed is favorably improved, the emission of ammonia nitrogen is reduced, the pollution to a water environment is alleviated, the anti-stress ability and the immunity of a salmo trutta fario linnaeus parent fish are improved, and the quality of sperm eggs is improved.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed products, and in particular relates to a Yadong salmon broodstock feed with low protein and amino acid balance. Background technique [0002] my country's aquaculture has developed rapidly. In the past, it was mainly free-range farming, but now it has a relatively high degree of scale and intensification. Intensive and factory farming can improve farming efficiency and reduce costs. On the other hand, the wastewater produced by large-scale farming also brings a series of environmental problems, causing water and soil pollution. Therefore, many nutrition scholars have begun to pay attention to the use of nutritional regulation technology to maximize the utilization of nutrients by animals, while reducing environmental pollution, which is of great significance to the health and sustainable development of cold-water fish. Excess nutrient emissions, mainly nitrogen and phosphorus, are important...
