Embodiment 1

[0020] A production method of the special feed for Procambarus clarkii added with fermented fish meal of the present invention adopts the following process steps: the formula ratio is calculated by weight per thousand:

[0021] (1) Cook the fish meal at a high temperature of 70°C for 15 minutes, then add the BGB high-temperature biological bacteria purchased from Beijing Jiabowen Biotechnology Co., Ltd., the addition amount is 0.7 g / kg, and stop heating after stirring for 30 minutes. When the temperature drops to 50°C, add 0.3 g / kg of BGB mesophilic bacteria and stir for 30 minutes, then transfer to a wooden box with a cover for secondary fermentation. The fermentation time is 60 hours, and then produced by Jiangsu Zhenxing Drying Machine Factory The disc dryer dries the material, and the drying temperature is 60°C-70°C.

[0022] (2) Soybean meal 250, subflour 320 and corn 100, firstly dried for 30-40 minutes, drying temperature: 60°C-80°C, then added fermented fish meal 250, ...

Embodiment 2

[0027] A production method of the special feed for Procambarus clarkii added with fermented fish meal of the present invention adopts the following process steps: the formula ratio is calculated by weight per thousand:

[0028] (1) Cook the fish meal at 70°C for 15 minutes, then add BGB high-temperature biological bacteria purchased from Beijing Jiabowen Biotechnology Co., Ltd., the addition amount is 0.5 g / kg, and stop heating after stirring for 30 minutes. When the temperature drops to 50°C-60°C, add 0.3 g / kg of BGB mesophilic bacteria and stir for 30 minutes, then transfer to a wooden box with a cover for secondary fermentation. The produced disc dryer dries materials at a drying temperature of 60°C-70°C.

[0029] (2) 200 grams of soybean meal, 340 grams of secondary flour and 120 grams of corn, firstly dried for 30 minutes at a temperature of 70°C, then 250 grams of fermented fish meal was added, and then the feed grinder produced by Shanghai Spring Valley Machinery Manufa...

Embodiment 3

[0034] A production method of the special feed for Procambarus clarkii added with fermented fish meal of the present invention adopts the following process steps: the formula ratio is calculated by weight per thousand:

[0035] (1) Cook the fish meal at a high temperature of 70°C for 15 minutes, then add the BGB high-temperature biological bacteria purchased from Beijing Jiabowen Biotechnology Co., Ltd., the addition amount is 0.7 g / kg, and stop heating after stirring for 30 minutes. When the temperature drops to 50°C-60°C, add 0.3 g / kg of BGB mesophilic bacteria and stir for 30 minutes, then transfer to a wooden box with a cover for secondary fermentation. The produced disc dryer dries materials at a drying temperature of 60°C-70°C.

[0036] (2) Soybean meal 240, subflour 300 and corn 90, firstly dried for 30 minutes, drying temperature: 70°C, then added fermented fish meal 280, and then the feed pulverizer produced by Shanghai Spring Valley Machinery Manufacturing Co., Ltd. ...

Abstract

The invention relates to a Procambrus clarkii special feed added with fermented fish meal and a production method thereof, which is characterized in that soybean meal, the fermented fish meal, wheat-middlings, corn and adhesives are ground and then mixed with fish oil, lecithin oil, monocalcium phosphate and multidimensional premix to prepare granule feed, the fermented fish meal treated by secondary fermentation is added and fully stirred, the uniformly mixed materials are extruded into the granule feed by a granulator in a conditioner via steam curing, and then the granule feed is packaged into finished product after being dried and cooled. The invention can resolve the fish meal into small peptides and amino acids which are beneficial to the digestion and absorption of the Procambrus clarkii; the generated small peptides and flavoured amino acids after the fish meal is fermented secondarily accelerate the growth speed of the Procambrus clarkii, promote the development of the immune organs of the Procambrus clarkii and can increase the survival rate of the Procambrus clarkii, and the breeding is standardized; and the fermented fish meal can improve feed efficiency and is beneficial to the reduction of production cost.

Description

technical field [0001] The invention relates to a feed formula for freshwater economical shrimps, in particular to a special feed for Procambarus clarkii added with fermented fish meal and a production method thereof. 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 researching and developing high-quality artificial special-purpose feed has become the top priority to satisfy the needs of breeding industry. Because the currently produced pellet feed is used in Procambarus clarkii aquaculture, there are generally problems such as high morbidity, low aquaculture survival rate and lack of special feed for shrimp fry, and the aquaculture effect is not ideal. Due to the existence of the above-mentioned defects, the ...
