preparation example Construction

[0027] The above-mentioned preparation method of grass carp extruded feed for reducing mortality in high temperature seasons comprises the following steps:

[0028] Imported fish meal, soybean meal, corn gluten meal, canola meal, secondary meal, flour, phospholipid powder, calcium carbonate, salt, calcium dihydrogen phosphate, choline chloride, lysine, methionine, vitamin C, zeolite powder, The multivitamin mixture, mineral trace element mixture, and traditional Chinese medicine additives are coarsely crushed, and the raw materials after the first mixing are adjusted and tempered in the modulator at 100-110°C for 2 minutes, and then heated at 90-100°C The temperature is puffed and granulated, dried at 85°C, sprayed with soybean oil, cooled to room temperature, graded, and packaged.

Embodiment 1

[0030] The grass carp extruded feed for reducing mortality in high temperature seasons of the present embodiment includes the following components by weight:

[0031] Imported fish meal 30g, soybean meal 380g, corn gluten meal 40g, canola meal 55g, subflour 150g, flour 200g, phospholipid powder 23g, soybean oil 22g, calcium carbonate 5g, salt 1g, calcium dihydrogen phosphate 2g, choline chloride 2g , 3g of lysine, 2g of methionine, 2g of vitamin C, 30g of zeolite powder, 3g of multivitamin mixture, 2g of mineral and trace element mixture, 48g of traditional Chinese medicine additives, 1000g in total.

[0032] Among them, 3g of multivitamin mixture includes 30mg of vitamin A and 24mg of vitamin B 1 , 24mg vitamin B 2 , 60mg vitamin B 6 , 0.3mg vitamin B 12 , 750mg vitamin C, 60mg calcium pantothenate, 75mg niacin, 12mg vitamin D 3 , 18mg vitamin K 3 , 15mg folic acid, 300mg inositol, 1631.7mg carrier defatted rice bran.

[0033] 2g mineral trace element mixture includes 1...

Embodiment 2

[0041] The grass carp extruded compound feed of embodiment 1 is carried out the large pond verification test of farm, randomly select 5 pond mouths (control groups) who feed a certain brand of grass carp extruded feed on the market, and 5 people who feed heat stress resistant grass carp extruded feed The stocking density of grass carp in Tangkou (experimental group), control group and experimental group is 2000-2100 / mu. Count the number of dead fish every day, the number of dead fish when pulling the net, and the number of dead fish during transportation when selling fish. The test time is 7.5-8.4 days, the water temperature is 29.7°C-34.1°C, and the average water temperature is 31.3°C. The results showed that the 5 ponds that fed a certain brand of grass carp extruded feed on the market died an average of 20.3±3.6 fish per day, 83.2±4.1 fish died on average when pulling the net, and 32.4±1.7 fish died on average during transportation. An average of 2.2±0.3 fish died every da...

Abstract

The present invention provides a grass carp puffed feed for reducing mortality in high temperature season. The grass carp puffed feed comprises 30 parts of imported fish meal, 380 parts of soybean meal, 40 parts of corn protein powder, 55 parts of low-erucic-acid and low-glucosinolate rapeseed meal, 150 parts of wheat middling, 200 parts of flour, 23 parts of phospholipid powder, 22 parts of soybean oil, 5 parts of calcium carbonate, 1 part of edible salt, 2 parts of calcium dihydrogen phosphate, 2 parts of choline chloride, 3 parts of lysine, 2 parts of methionine, 2 parts of vitamin C, 30 parts of zeolite powder, 3 parts of a multivitamin mixture, 2 parts of a mineral trace element mixture and 48 parts of a traditional Chinese medicine additive. Honeysuckle, lotus leaves and licorice have effects on clearing away heat, removing toxins, eliminating heat and reducing dampness, and have a very good summer-heating reducing function for grass carps in high temperature. Wrinkled gianthyssop herb, purple perilla and poria cocos improve a gastrointestinal function of the grass carps and promote effective absorption of nutrients. Radix codonopsis, Chinese angelica, white atractylodes rhizome, fructus psoraleae, fiveleaf gynostemma herb and dandelion enhance the immunity of the grass carps, reduce incidence of the grass carps, and thus reduce mortality.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to an extruded grass carp feed for reducing mortality in high temperature seasons and a preparation method thereof. Background technique [0002] Grass carp is the main freshwater fish farming object in China because of its rapid growth and wide source of feed. According to the statistics of "China Fishery Yearbook (2012)", the national grass carp farming output has reached more than 4.4 million tons, accounting for 1% of the total freshwater fish farming output. / 4 or so. In recent years, due to the substantial increase in production costs such as feed, rent, seedlings, medicines, and wages, farmers have had to increase breeding production by increasing stocking density in order to balance the ever-increasing breeding costs. However, the continuous increase in stocking density and production has resulted in the continuous compression of the water body space in which fish per kilogram live...
