Abstract

The invention discloses a high-digestion high-utilization-rate catfish feed, and belongs to the technical field of processing of catfish feeds. Based on nutritional requirements of catfish and water body environment, the digestion characteristics of the catfish are combined, the formula of a conventional catfish feed is optimized, and a feed complex enzyme, wormwood seed powder, a prunus humilis bunge extract and a phagostimulant are scientifically compounded, so that the catfish feed can be prepared, wherein the feed complex enzyme can effectively degrade anti-nutritional factors in the catfish feed, increase the utilization rate of nutrient substances of starch, protein, minerals and the like, increase the protein level, the organism antioxidative activity and the digestive absorption rate of the catfish, significantly increase the digestibility and the production properties of the catfish, reduce the feed coefficient, prevent the water bodies from being polluted and maintain good water quality is scientifically compounded; the wormwood seed powder can significantly improve the caking property, the water resistance, the glossiness and the frost resistance of the catfish feed and reduce the powder containing rate of the feed; the prunus humilis bunge extract can effectively complement calcium, ferrum and soluble fibers; the phagostimulant can substantially improve the palatability of the feed; and therefore, the catfish feed is good in feed coefficient, high in digestibility, good in production properties, high in propagation properties, high in disease resistance, high in palatability and low in cost.

Description

technical field [0001] The invention relates to catfish feed processing, in particular to a catfish feed with high digestibility and utilization rate. Background technique [0002] Aquatic feed is different from livestock and poultry feed, and has higher requirements on feed formula, raw material crushing particle size, pelleting temperature, water resistance, and powder content. Therefore, the aquatic feed processing process is also significantly different from the livestock and poultry feed production. The feed processing technology directly affects the quality of aquatic feed, such as feed uniformity, sedimentation, pulverization rate, surface gloss and water resistance, etc. . Reasonable feed formula and processing technology can significantly improve the digestion and absorption rate of feed, increase the water stability of feed, reduce the pollution of feed to water, and prolong the feeding time of fish. [0003] Catfish is an animal-eating fish and an excellent vari...
