[0003] At present, with the popularization of artificial feeding, people feed rainbow trout with compound feed, but the nutrients in the ingredients are not very reasonable, and the content of various proteins and vitamins is relatively low. Therefore, the growth of rainbow trout is slow and the color of the body surface is dim. , pale meat, poor taste and other problems directly affect the commodity value of rainbow trout

Abstract
The invention discloses a compound feed for enhancing color of rainbow trout. The compound feed is prepared from the following raw materials in parts by weight: 0.1-0.3 part of microelements, 0.03-0.06 part of vitamins, 1-2 parts of minerals, 15-25 parts of imported fish powder, 5-10 parts of shrimp shell powder, 2-5 parts of sleeve-fish ointment, 20-40 parts of bean pulp, 10-20 parts of mixed meal, 5-8 parts of corn protein powder, 2-3 parts of alfalfa powder, 0.04-0.08 part of cholate substances, 1-2 parts of spirulina powder, 4-6 parts of kelp powder, 4-6 parts of grease, 0.02-0.04 part of astaxanthin, 0.2-0.4 part of 0.2% lutein and 15-25 parts of flour. The raw materials such as the imported fish powder and the good-quality bean pulp are selected for meeting nutritional indexes of the rainbow trout, and the carotenoid-rich raw materials such as the spirulina powder, the astaxanthin, the lutein and the corn protein powder are emphatically added for enhancing the color of the rainbow trout according to physiological characteristics of the rainbow trout; the compound feed is convenient to use and free from toxic effects, and contains 40%-45% of crude proteins and 12%-16% of crude fat.
Description
Technical field: [0001] The invention relates to a feed, in particular to a compound feed for color enhancement of rainbow trout. Background technique: [0002] Rainbow trout, known as "water ginseng", belongs to Herringomorpha and Salmonidae. Maximum body length: 120cm, habitat depth: 0-5 meters, also known as waterfall fish and seven-color fish. Rainbow trout like to live in clear and pollution-free cold water. They mainly eat fish and shrimp. They are alpine fish and can only grow in water temperatures below 20°C. It has high requirements for living conditions and is a delicate fish species. Rainbow trout is a famous and high-quality fish with high economic value, which is favored by farmers and consumers because of its tender meat, delicious taste and rich nutrition. [0003] At present, with the popularization of artificial feeding, people feed rainbow trout with compound feed, but the nutrients in the ingredients are not very reasonable, and the content of various p...
