Some existing studies have shown that the differences in molecular composition and content of starch materials from different sources have a very significant impact on fish growth performance, protein efficiency, etc. The difference in the release rate affects the activity and expression of 6-phosphofructokinase-1 and pyruvate kinase in the glycolysis process and the fructose bisphosphatase in the gluconeogenesis pathway, which in turn affects the fat synthesis, volatile fatty acid production, Glycogen accumulation in the liver, fat deposition in the mesentery, and digestion and absorption of other nutrients can even lead to metabolic diseases such as fatty liver
At present, in the field of aquaculture, there is no feed formula that clearly proposes the use and proportion of starch raw materials in the feed

Abstract
The invention relates to a sugar feed for improving the growth of bream and a preparation method thereof. The feed is mainly prepared from the following raw materials: 4-8 parts of fish meal, 24-30 parts of soybean meal, 14-19 parts of rapeseedmeal and 12 parts of cotton meal ~17 parts, soybean oil 2-5 parts, fish oil 2-5 parts, wheat starch 6-12 parts, corn starch, sorghumstarch or tapioca starch 6-12 parts, corn gluten 0-2 parts, microcrystallinefiber 5-7 parts of vegetarian, 0.4 part of salt, 0.8 part of zeolitepowder, 1.8 part of calcium dihydrogen phosphate and 1 part of intensive fish compound premix. The above-mentioned raw materials are pulverized, stirred and mixed in a mixer, and water vapor is introduced to form particles with a particle size of 1-2 mm, which is then dehydrated, cooled and dried. The sugar feed of the present invention solves the problem of single starch source in the current ball-head bream feed, and can not only improve the growth speed and muscle quality of ball-head bream, but also reduce the production cost of the feed by matching starch raw materials from different sources in a reasonable proportion. , improve the utilization rate of feed.
Description
technical field [0001] The invention belongs to the technical fields of aquaculture, nutrition control and feed processing, and in particular relates to a sugar feed for improving the growth of bream and a preparation method thereof. Background technique [0002] Carbohydrates are important raw materials for the synthesis of body fat and non-essential amino acids. They exist in the liver and muscle in the form of liver glycogen and muscleglycogen, respectively, and provide energy for the life activities of fish. They also participate in the composition of fish in the form of mucopolysaccharides. Somatic tissue, and participate in the immune regulation of the body in the form of glycoproteins. Compared with fat and other energy sources, sugar is a relatively cheap energy raw material, which has the advantages of high yield and wide range of sources. Appropriately increasing the use of sugar in feed can save the amount of protein, thereby reducing feed costs. . In addition,...
