Problems solved by technology

Since Procambarus clarkii has high cellulose content aquatic plants are one of its main food in the breeding process, because the cellulose is difficult to be digested and absorbed by Procambarus clarkii, and the foraging ability of Procambarus clarkii is poor, the feeding Part of the fed feed is converted into fertilizer, which is a big waste
The main reason is that the currently produced pellet feed does not contain cellulase, and most of the feeds have problems such as poor food attraction, low digestibility and unsatisfactory breeding effect.
Due to the existence of the above-mentioned defects, the survival rate and yield of the existing Procambarus clarkii artificial culture are generally low, and the breeding benefits are difficult to improve

Embodiment 1

[0024] The present invention is a production method of a special feed capable of improving the immunity and output of Procambarus clarkii, which mainly adopts the following process steps: the formula ratio is calculated by weight per thousand:

[0025] (1) Take soybean meal 250, fish meal 200, secondary meal 290, cotton meal 30, and corn 70, first pass through the tray dryer produced by Jiangsu Zhenxing Drying Machine Factory, and the drying temperature is 60°C-70°C, The drying time is 2-3 hours, 50% of fermented shrimp shell powder is added, and then the feed grinder produced by Shanghai Chungu Machinery Manufacturing Co., Ltd. is used for ultrafine grinding, so that the fineness of raw materials reaches 100 mesh.

[0026] (2) Add multi-dimensional premix 20, α starch 20, fish oil 20, phospholipid oil 10, calcium dihydrogen phosphate 10, and broken yeast into the ultrafinely pulverized soybean meal, fish meal, secondary meal, cotton meal and corn Powder 30 and embedded cellul...

Embodiment 2

[0030] The present invention is a production method of a special feed capable of improving the immunity and output of Procambarus clarkii, which mainly adopts the following process steps: the formula ratio is calculated by weight per thousand:

[0031] (1), get soybean meal 250, fish meal 240, secondary meal 270, cottonseed meal 40, and corn 40 and first pass through the disc dryer produced by Jiangsu Zhenxing Drying Machine Factory, and the drying temperature is 70°C. The time is 2 hours, 50% of fermented shrimp shell powder is added, and then the feed grinder produced by Shanghai Spring Valley Machinery Manufacturing Co., Ltd. is ultrafinely pulverized, and mixed evenly, so that the fineness of raw materials reaches 110 mesh.

[0032] (2) Add multi-dimensional premix 20, α starch 20, fish oil 20, phospholipid oil 10, calcium dihydrogen phosphate 10, and broken yeast into the ultrafinely pulverized soybean meal, fish meal, secondary meal, cotton meal and corn The powder 30 an...

Embodiment 3

[0036]The present invention is a production method of a special feed capable of improving the immunity and output of Procambarus clarkii, which mainly adopts the following process steps: the formula ratio is calculated by weight per thousand:

[0037] (1) Take soybean meal 200, fish meal 250, secondary meal 290, cotton meal 30, and corn 70 and dry it at 60°C-70°C for 2-3 hours, then add fermented shrimp shells Powder 50, then ultra-finely pulverized by the feed grinder produced by Shanghai Spring Valley Machinery Manufacturing Co., Ltd., and mixed evenly, so that the fineness of raw materials reached 120 mesh.

[0038] (2) Add multi-dimensional premix 20, α starch 20, fish oil 20, phospholipid oil 10, calcium dihydrogen phosphate 10, and broken yeast into the ultrafinely pulverized soybean meal, fish meal, secondary meal, cotton meal and corn The powder 30 and the embedded cellulase 0.001 were stirred and mixed to form a mixture. The activity of the cellulase is 200,000 inter...

Abstract

The invention relates to a feed capable of improving immunity and yield of Procambrus clarkii and a production method thereof. The method is characterized in that: after being processed and smashed, bean pulp, fish meal, wheat middling, corns and adhesive are mixed with fish oil, phosphatide oil, monocalcium phosphate and multidimensional premix to be prepared into granulated feed; and embedded cellulase, breaking yeast powder and fermentation shrimp shell meal are added to be fully stirred to be prepared into the granulated feed. The invention can change parts of cellulose taken by the Procambrus clarkii into saccharide, thereby being favourable for lowering feed coefficients; shrimp shell powder can kill the pathogen in shrimp shells after being performed with high-temperature fermentation; meanwhile, the chitin in the shrimp shells is decomposed into chitosan and oligosaccharide to improve the immunity and the survival rate of the Procambrus clarkia; and the breaking yeast with obvious food calling effect is added to improve the utilization ratio of the feed, thereby being favourable for improving cultivation yield and benefits.

Description

technical field [0001] The invention relates to a feed formula for freshwater economical shrimps, in particular to a production method of a special feed capable of improving the immunity and yield of Procambarus clarkii. Background technique [0002] Procambarus clarkii is native to North America and is commonly known as freshwater crayfish. It belongs to Arthropoda, Crustacea, Decapod, and Cricketidae in classification. It was introduced to my country in 1929 and has become one of the main freshwater species in my country. Therefore develop the artificial feed that is rich in nutrition, good food attractant and has the raising survival rate of Procambarus clarkii has caused the industry's general concern. Since Procambarus clarkii has high cellulose content aquatic plants are one of its main food in the breeding process, because the cellulose is difficult to be digested and absorbed by Procambarus clarkii, and the foraging ability of Procambarus clarkii is poor, the feeding ...
