Embodiment 1

[0030] Embodiment 1: A kind of feed of yellow catfish, its basic formula is made up of following components, in terms of air-dried matter weight percentage, contains, fish meal 27%, soybean meal 11%, rapeseed meal 5.5%, cotton meal 5%, wheat bran 17%, 9% corn, 9% shrimp shell powder, 5.5% corn gluten powder, 6% corn gluten powder, 1% vegetable oil, 1% soybean oil, 2% calcium dihydrogen phosphate, and 1% additives.

[0031] The ratio of feed ingredients in this embodiment is reasonable, wherein, the crude protein is 40.02%, the crude fat is 8.24%, the moisture is 7.00%, the crude ash is 13.98%, the calcium content is 3.13%, the phosphorus content is 1.86%, and the total energy is 18.54%. kJ / g.

[0032] The feed of the present embodiment was used to cultivate the yellow catfish in laboratory culture tanks. After two months of cultivation, the body color turned yellow obviously.

[0033] The feed formula of the control group was: fish meal 27%, soybean meal 18%, rapeseed meal 5....

Embodiment 2

[0036] Embodiment 2: A kind of feed of yellow catfish, its basic formula is made up of following components, in air-dry matter weight percentage, contains, fish meal 24%, soybean meal 18%, rapeseed meal 5.5%, cotton meal 5%, wheat bran 8%, blood meal 3%, shrimp shell powder 9%, sub meal 7.5%, corn gluten meal 6%, corn 9%, vegetable oil 1%, soybean oil 1%, calcium dihydrogen phosphate 2%, additive 1%.

[0037] Adopt the feed of present embodiment to carry out six acres of water surface culture, culture 1 month, body color is significantly improved than the yellow catfish that ingests other feeds.

Embodiment 3

[0038] Embodiment 3: A kind of feed of yellow catfish, its basic formula is made up of following components, in terms of air-dried matter weight percentage, contains, fish meal 21%, soybean meal 10%, rapeseed meal 12.5%, cotton meal 5%, wheat bran 8%, blood meal 3%, shrimp shell powder 9%, meat meal 4%, sub meal 7.5%, corn gluten meal 6%, corn 9%, vegetable oil 1%, soybean oil 1%, calcium dihydrogen phosphate 2%, additive 1% .

[0039] Adopt the feed of present embodiment in Nantong area, 20 mus of water surfaces are cultivated 1 month, and the yellow catfish body color that eats other feeds has the phenomenon of turning white and lightening, but the yellow catfish that ingests this formula can maintain its body color.

Abstract

The invention discloses a yellow cartfish feedstuff which comprises animal protein, plant protein, fat source, minerals and vitamin additives, wherein the minerals include the salts of Cu, Fe, Mn and Zn, characterized in that, calculated by the content of dried solid (by weight percent), the feed contains 5-10% of maize protein meal.

Description

technical field [0001] The invention relates to a feed for aquatic animals, in particular to a feed for yellow catfish, which can make the artificially cultured yellow catfish have a brighter body color. Background technique [0002] With the development of intensive aquaculture and the wide application of artificial feed, the cycle of aquatic product cultivation has been effectively shortened, and the output of aquatic products has been greatly increased. However, the color and luster of artificially cultured aquatic products is usually far inferior to that of natural products or aquatic products fed with fresh bait, and lacks the healthy body color that natural aquatic products have. In recent years, with the continuous improvement of people's living standards, the color of aquatic products has become an important reference for people to choose and buy. The color of artificially farmed aquatic products has seriously affected its commodity value....
