Embodiment 1

[0058] Embodiment 1 Raw material preparation

[0059] 1. Preparation of Yeast Culture

[0060] The preparation method of the yeast culture comprises the following steps: take the Saccharomyces cerevisiae tlj2016 slant strain after 1 ring activation, inoculate it into a 500mL Erlenmeyer flask containing 100mL seed medium, and cultivate it at 30°C with a shaker speed of 150r / h. Cultivate under the min condition for 28h to obtain the primary seed liquid; the primary seed liquid is inoculated into a 500mL Erlenmeyer flask containing 100mL fermentation medium at an inoculum size of 8% (v / v) for fermentation and cultivation, and the fermentation time is 28h. The temperature is 30°C, the rotating speed of the shaker is 180r / min, and the secondary seed liquid is obtained; the secondary seed liquid is inserted into a 5L fermenter with 3L fermentation medium for constant temperature fermentation with an 8% (v / v) inoculum, and the temperature is 30°C , the ventilation rate is 5L / min, th...

Abstract

The invention discloses a processing method for a catfish feed with a high digestion and utilization rate. The catfish feed provided by the invention is developed on the basis of the nutritional demands of catfish, a water environment and the digestion characteristics of the catfish and formulated through optimization of conventional formulas for the catfish feed. The catfish feed with low feed coefficient, high digestion rate, good production performance, high reproductive performance, strong disease resistance, good palatability and low cost is eventually prepared through scientific compounding of the following components: feed complex enzyme capable of degrading anti-nutritional factors, increasing the utilization rates of nutrients like starch, protein and mineral matters, improving the protein level, antioxidation activity and digestion and absorption rate of the catfish, substantially enhancing the digestion rate and production performance of the catfish, lowering feed coefficient, preventing water pollution and maintaining excellent water quality; wormwood seed powder capable of substantially enhancing the bonding performance, water resistance, glossiness and frost resistance of the catfish feed and lowering the powder content of the feed; Chinese dwarf cherry extract capable of effectively supplementing calcium, iron and soluble fiber; and a feeding attractant capable of greatly improving the palatability of the feed.

Description

technical field [0001] The invention relates to catfish feed processing, in particular to a processing method of catfish feed with high digestibility 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 ...
