Feed for improving body color and meat quality of yellowhead catfish and preparation method thereof

Abstract

The present invention relates to a feed for improving body color and meat quality of yellowhead catfish and a preparation method thereof, and belongs to the field of feeds. The feed comprises white fish meal, casein, Antarctic krill powder, corn germ oil, fish oil, cuttlefish liver oil, konjac starch, dextrin, peanut bran, calcium dihydrogen phosphate, compound vitamins, compound minerals, fermented plant powder, a traditional Chinese medicinal additive and porphyridium powder. The feed is reasonable in formula; the components have synergistic and complementary functions; the components are combined to promote the growth of the yellowhead catfish; the feed improves the body color and meat quality of the yellowhead catfish, is good in effects and stable, and can reduce ammonia and nitrogenemission in water. Conditions for producing the green feeds and aquatic products are created. The preparation method is as follows: the raw materials are mixed in ratios. The method is simple and rapid, good in condition controllability, good in feed stability and very good in application prospects.

Description

technical field [0001] The invention relates to the field of feed, and in particular relates to a feed for improving the body color and meat quality of peltatus catfish and a preparation method thereof. Background technique [0002] Peeled catfish has tender meat, few thorns and no scales, delicious taste and rich nutrition. It is favored by farmers and consumers and has high economic value. In recent years, under the conditions of large-scale farming, due to the high price of fish meal, the immaturity of feed formulation technology or fish meal replacement technology, and the low level of breeding management technology, the yellow catfish has symptoms of light body color and poor meat quality, while the fish’s Body color and meat quality are indicators that consumers value very much, and their deterioration will directly lead to a decline in commodity value and seriously affect the income of farmers. [0003] The body color change of fish is mainly related to factors such ...

AI Technical Summary

Problems solved by technology

At present, the regulation of body color of yellow catfish is mainly through supplementing the feed with carotenoids, which cannot be synthesized by the fish itself, but play a major role in the appearance of body color. Carotenoids are fat-soluble substances, so the fat source and The fat level plays an important role in the deposition of pigments. At the same time, the nutritional imbalance and harmful substances in the feed (such as feed fat oxidation, raw material toxins, etc.) will affect the overall physiological functions of fish and cause changes in their body color. Easily overlooked in color control
