Problems solved by technology

At present, although the compound feed used in river crab breeding has been improved and improved in nutritional content, its amino acid and fatty acid content is still relatively unbalanced, and its water resistance is not high, especially the sinking granular feed, which will cause damage to the breeding water after being put into it. Pollution is not conducive to the sustainable and healthy development of river crab farming

Abstract

The invention discloses a special compound feed for crabs. The compound feed consists of soybean meal, rapeseed meal, peanut meal, corn protein powder, spray-dried animal blood cells, fish meal, shrimp meal, four, fish dissolving-pulp protein powder, yeast extract, fish oil, soybean lecithin oil, bentonite, monocalcium phosphate, a mildew preventive, mannan oligosaccharide, glycine betaine, a hulling element, methionine, choline, perilla seed extract, a vitamin premix and a mineral premix. The raw materials of the compound feed are stable in source, high in utilization ratio, balanced in nutrient content and relatively low in cost. The preferred fish dissolving-pulp protein powder enhances the feed attraction of the feed. An advanced puffing process is adopted so as to further improve the utilization ratio and water resistance of the feed and reduce waste and water pollution. Meanwhile, an immune nutrition additive is adopted so as to significantly enhance the immune function and anti-stress capacity of the crabs and significantly increase the survival rate. The compound feed is much greener and more environmentally friendly, and efficiency increase is particularly significant in a high-density river crab breeding mode.

Description

technical field [0001] The invention belongs to the technical field of feed production, and in particular relates to a special compound feed for river crabs and a preparation method thereof. Background technique [0002] Chinese mitten crab ( Eriocheir sinensis ), also known as river crabs, are widely distributed in lakes along the north and south coasts of my country, among which the Yangtze River system has the largest output and the most delicious taste. At present, river crab farming has formed a large scale, except for a small number of which are still fed chilled, most of them use compound feed for farming. However, as the density of river crab breeding becomes higher and higher, river crabs are faced with a large number of stress responses, such as changes in nutrition, environment and metabolism, and the incidence rate increases. Therefore, river crab farming has higher requirements for feed. In addition, waste and discharge should be reduced as much as possible to...
