Puffed floating compound feed for preventing flesh color of ietalurus punetaus from yellowing and production process thereof

Abstract

The invention relates to a puffed floating compound feed for preventing flesh color of ietalurus punetaus from yellowing and a production process thereof, and belongs to the technical field of breeding of aquatic products such as fishes. The feed disclosed by the invention comprises the following raw materials in parts by weight: 8-10 parts of fish meal, 20-25 parts of bean pulp, 20-25 parts of rapeseed meal, 8-10 parts of rice protein powder, 18-22 parts of flour, 8-10 parts of rice bran, 1-1.5 parts of monocalcium phosphate, 1-2 parts of soybean oil, 0.15-0.3 part of choline chloride, 1-2 parts of bentonite, 0.1-0.3 part of lysine hydrochloride, 0.1-0.3 part of a mildew preventive, 0.02-0.05 part of L-carnitine, 0.02-0.05 part of an antioxidant compound, 0.3-0.5 part of compound vitamin premix and 2-3 parts of compound trace element premix. By adjusting the feed formula structure, the feed achieves the effects of optimizing feed ingredients, enhancing fish immunity and intestinal health, promoting digestive absorption and muscle deposition and improving the muscle quality; and finally, the muscle yellowing ratio of the ietalurus punetaus under normal water quality and high-density feeding conditions can be reduced, the economic losses are reduced, and the economic benefits are improved.

Description

technical field [0001] The invention relates to a feed for fish and aquatic products and a production process thereof. More specifically, the invention relates to a puffed floating compound feed for preventing channel catfish from turning yellow in color and a production process thereof. The invention belongs to the technical field of fish and aquatic products farming. Background technique [0002] Channel catfish, also known as American catfish and channel catfish, belongs to Siluriformes, Catfish family, is a freshwater warm-water fish, native to North America, the fish was introduced to my country in 1984, and artificial breeding was successful in 1987. It has the characteristics of wide range, miscellaneous food habits, wide temperature adaptability, strong disease resistance, fast growth, high yield, easy breeding, fresh and tender meat, and easy fishing. It has been cultivated on a large scale in my country. Because there are no intermuscular spines in the muscles, it ...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned first document is aimed at preventing the body color of channel catfish, but does not involve muscle color, and cannot prevent the yellowing of fish muscles

In addition, the feed is pellet feed, and the stability in water is insufficient

[0007] The above-mentioned second document is a feed additive for channel catfish. It does not propose a complete feed formula, nor can it prevent the yellowing of fish muscles.
