Coating feed with high water stability for improving metabolic level and oxidation resistance of black carps by lutein and preparation method of coating feed

Abstract

The invention discloses coating feed with high water stability for improving metabolic level and oxidation resistance of black carps by lutein and a preparation method of the coating feed. According to the living habit and nutritional requirements of the black carps, the coating feed is reasonably prepared in terms of raw material selection, nutritional requirements, processing technology and the like, so that the black carp feed is comprehensive in nutrition and reasonable in structure and can solve the problems of low digestibility, poor dyspepsia, developmental retardation and the like due to feed. Moreover, the metabolic level of the black carps can be improved, the oxidation resistance of a body is enhanced, and the nutrient content and the grade level of fish meat are improved. Compared with traditional feed, the coating feed has the advantage that the black carps cultured by the feed are rapid in growth, high in yield and delicious in meat flavor. Moreover, the fish meat has the functions of preventing cardiovascular diseases, preventing diabetes, resisting cancer and the like. The feed is environmentally friendly, green, free from chemical substances such as antibiotics and hormone, culture benefits can be effectively improved, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a coating feed which improves the metabolic level and antioxidant capacity of herrings through lutein and has high water stability and a preparation method thereof. Background technique [0002] Herring is one of the four traditionally farmed fish in my country. It is distributed in the eastern, southern, central and northeastern regions of China. It is sweet in taste, flat in nature, and belongs to the liver meridian. The effects of beriberi damp arthralgia, weakness of the waist and feet, epigastric pain, and dysentery. In recent years, the demand for herring in the Chinese market has continued to increase, and more and more intensive and large-scale farming of herring has been carried out with compound feed. However, the content and ratio of the nutrients contained in the existing feed are unreasonable, so that the utilization rate of the nutrients in the feed by the herri...

Problems solved by technology

This formula has the following deficiencies: one is that the feed ingredients are relatively lacking, especially the green feed and vitamin content are scarce, which not only leads to the lack of feed nutrition, but also causes the decline of fish meat quality; It is a conventional crushing, mixing, tempering, and granulating technology, which lacks preprocessing and flavoring treatment of various raw materials, resulting in a greatly reduced taste and taste of feed products, which is not conducive to improving appetite; Coating treatment leads to poor stability in water, and part of the feed is directly dissolved by water without eating in time, resulting in great waste of feed and serious pollution of water
