Problems solved by technology

The edible value of rainbow trout makes the muscle red degree an important indicator for evaluating its quality; however, the redness of the existing cultured rainbow trout muscles gradually decreases, which reduces the degree of consumer acceptance and affects its economic value
[0003] At present, the change of the redness of rainbow trout muscles is mainly through adding corresponding pigments in the feed. However, the pigments used in the feed are usually chemically synthesized and expensive, and because the pigments are added to the feed only to improve the color of the meat, there is no other nutritional function, thus greatly increasing the cost of feed
In addition, the chemical properties of these pigments themselves are unstable, and their commercial forms usually need to be coated or microencapsulated to block air and enhance their stability. Different coating materials will affect the digestion, absorption and utilization of pigments, and affect the biological potency

Embodiment 1

[0041] This embodiment is a feed for rainbow trout, which includes the following raw materials in parts by weight: 30 parts of red fish meal, 20 parts of Antarctic krill meal, 4 parts of soybean meal, 5 parts of soybean oil, 7 parts of fish oil, and 3 parts of soybean lecithin , 15 parts of wheat flour, 6 parts of rice husk powder, 1 part of vitamin premix, 2.5 parts of mineral premix, 0.3 part of choline chloride, 0.5 part of calcium dihydrogen phosphate, 0.15 part of antifungal agent, 0.2 part of antioxidant share;

[0042] Kjeldahl method (2300-automatic Kjeldahl nitrogen analyzer, FOSS, Denmark) and Soxhlet extraction method (36680-extractor, BUCHI, Switzerland) were used to detect the fat and protein in the above rainbow trout feed , the detection result is that the fat content is 19.24%, and the protein content is 42.3%.

Embodiment 2

[0044] This embodiment is a feed for rainbow trout, which includes the following raw materials in parts by weight: 30 parts of red fish meal, 20 parts of Antarctic krill meal, 4 parts of soybean meal, 5 parts of soybean oil, 7 parts of fish oil, and 3 parts of soybean lecithin , 15 parts of wheat flour, 6 parts of rice husk powder, 1 part of vitamin premix, 2.5 parts of mineral premix, 0.3 part of choline chloride, 0.5 part of calcium dihydrogen phosphate, 0.15 part of antifungal agent, 0.2 part of antioxidant share;

[0045] Wherein, the antifungal agent is composed of fumaric acid and calcium propionate in a ratio of 1:1 in parts by weight;

[0046] Antioxidant Ethoxyquinoline.

[0047] The fat and protein in the above-mentioned rainbow trout feeding feed were detected by the detection method of Example 1, and the detection results showed that the fat content was 19.17%, and the protein content was 42%.

Embodiment 3

[0049] This embodiment is a feed for rainbow trout, which includes the following raw materials in parts by weight: 40 parts of red fish meal, 15 parts of Antarctic krill meal, 1.5 parts of soybean meal, 7 parts of soybean oil, 5 parts of fish oil, and 1 part of soybean lecithin , 25 parts of wheat flour, 3 parts of rice husk powder, 2.5 parts of vitamin premix, 1.5 parts of mineral premix, 0.2 part of choline chloride, 2 parts of calcium dihydrogen phosphate, 0.05 part of antifungal agent, 1 part of antioxidant share;

[0050] Wherein, antifungal agent is fumaric acid;

[0051] Antioxidant Ethoxyquinoline.

[0052] The fat and protein in the above-mentioned rainbow trout feed were detected by the detection method of Example 1, and the detection results showed that the fat content was 20.81%, and the protein content was 41.24%.

Abstract

The present invention relates to an oncorhynchus mykiss raising feed and application thereof. The oncorhynchus mykiss raising feed comprises the following raw materials in parts by weight: 30 to 40 parts of red fish meal, 15 to 20 parts of Antarctic krill powder, 1.5 to 4 parts of soybean meal, 5 to 7 parts of soybean oil, 5 to 7 parts of fish oil, 1 to 3 parts of soybean lecithin, 15 to 25 partsof wheat flour, 3 to 6 parts of rice hull powder, 1 to 2.5 parts of a vitamin premix, 1.5 to 2.5 parts of a mineral premix, 0.2 to 0.3 part of choline chloride and 0.5 to 2 parts of monocalcium phosphate. The oncorhynchus mykiss raising feed can satisfy various nutritional requirements of oncorhynchus mykiss, promotes the absorption and utilization of nutrient substances by oncorhynchus mykiss, isbeneficial to the growth and development of the oncorhynchus mykiss, and has low feed coefficients. Besides, the feed can improve the muscle color of the oncorhynchus mykiss, effectively solves the problem that the red degree of muscle of cultured oncorhynchus mykiss is low, and improves the commodity value.

Description

technical field [0001] The invention relates to the field of rainbow trout feeding, in particular to a feed for feeding rainbow trout and an application thereof. Background technique [0002] Rainbow trout (Oncorhynchus mykiss) belongs to the subphylum Vertebrata, Teleost, Salmoniformes, Salmonidae, Salmonidae, and is known as "Ginseng in Water". one of the classes. The edible value of rainbow trout makes the muscle red degree an important indicator for evaluating its quality; however, the existing cultured rainbow trout muscle red degree gradually decreases, which reduces consumer acceptance and affects its economic value. [0003] At present, the change of the redness of rainbow trout muscles is mainly through adding corresponding pigments in the feed. However, the pigments used in the feed are usually chemically synthesized and expensive, and because the pigments are added to the feed only to improve the color of the meat, there is no other Nutritional function, thus gr...
