High-fat low-sugar micropterus salmoides expanding feed

Abstract

The invention discloses a high-fat low-sugar micropterus salmoides expanding feed, which is prepared from the following raw material components: fish meal, bean pulp, wheat gluten powder, soybean protein concentrate, flour, phagostimulant, zeolite powder, fish oil, soyabean lecithin powder, monocalcium phosphate, a mineral substance mixture, a vitamin mixture, choline chloride, a mould inhibitor and an antioxidant, wherein the phagostimulant is prepared from enzymolysis fish soluble, a shrimp paste and a yeast extract. According to the high-fat low-sugar micropterus salmoides expanding feed provided by the invention, the flour content is lower, so that the sugar content in a formula is reduced, the fish oil content is improved, the demands of micropterus salmoides on nutrition and energy can be met, the liver burden of the micropterus salmoides is reduced, and the liver health of the micropterus salmoides can be effectively protected; in addition, the zeolite powder and the special phagostimulant are additionally added, the expanding feed sinks slowly, and the micropterus salmoides is also induced to intake food, the micropterus salmoides can intake food at an upper water level, a middle water level and a lower water level, the competition for food is reduced, and the feed waste is reduced, so that the invention is the high-fat low-sugar micropterus salmoides expanding feed with high feeding attraction and less liver burden.

Description

technical field [0001] The invention relates to California perch extruded feed, in particular to a high-fat and low-sugar California perch extruded feed. Background technique [0002] The California perch, formerly known as the largemouth bass, belongs to the order Perciformes and the sunfish family in taxonomy. Native to the Mississippi River system in California, U.S.A., it is a rare carnivorous fish with delicious meat, strong disease resistance, rapid growth, easy catch and wide temperature adaptability. Because of its tender meat, delicious taste, and no intermuscular thorns, it is deeply loved by people and is a cultured species with great development potential in the future. Traditional California perch farming mainly uses chilled fish as bait, which has the disadvantages of unbalanced nutrition, water pollution and the growth of pathogenic bacteria, and frequent diseases, which affect the quality of California perch products and the healthy development of the aquacu...

Problems solved by technology

However, at present, the effect of extruded feed for California sea bass is uneven, and it cannot replace iced fresh fish throughout the whole process. Compared with the effect of iced fish farming, the main problems are the decline in attracting food and liver problems, which affect the promotion of extruded feed. For example, farmers generally report that the feed After the fish body size reaches 3 taels, the farmed California sea bass has white liver, swelling, and slow growth.

The reason is that California sea bass is a typical carnivorous fish, which has a good utilization rate of protein and fat, but a poor utilization rate of sugar, and too much sugar in the formula will accumulate in the liver of the fish and erode the liver Parenchymal cells, leading to liver dysfunction
