Problems solved by technology

Macrobrachium rosenbergii is currently cultured in freshwater rivers and brackish waters. However, giant macrobrachium rosenbergii cultured in fresh water tends to have soft shells and thinness. The ability to resist stress during transportation is low, and a large number of deaths are caused after long-distance transportation.

Embodiment 1

[0021] A feed additive premix for Macrobrachium rosenbergii anti-soft shell disease, based on the amount added in 1000kg Macrobrachium rosenbergii compound feed, the dosage of each component of the premix is ​​as follows:

[0022] Magnesium sulfate monohydrate 1200g, potassium dihydrogen phosphate 900g, calcium dihydrogen phosphate 12200g, vitamin D3 10g, lysolecithin 430g, copper glycinate 60g, chromium methionine 200g, total 15000g.

[0023] The above-mentioned components are put into the mixer in descending order of consumption to form a premix, and then the premix is ​​added to the compound feed for Macrobrachium rosenbergii.

Embodiment 2

[0025] A feed additive premix for Macrobrachium rosenbergii anti-soft shell disease, based on the amount added in 1000kg Macrobrachium rosenbergii compound feed, the dosage of each component of the premix is ​​as follows:

[0026] Magnesium sulfate monohydrate 800g, potassium dihydrogen phosphate 1000g, calcium dihydrogen phosphate 20000g, vitamin D3 5g, lysolecithin 1000g, copper glycinate 50g, chromium methionine 400g, total 23255g.

[0027] The above-mentioned components are put into the mixer in descending order of consumption to form a premix, and then the premix is ​​added to the compound feed for Macrobrachium rosenbergii.

Embodiment 3

[0029] A feed additive premix for Macrobrachium rosenbergii anti-soft shell disease, based on the amount added in 1000kg Macrobrachium rosenbergii compound feed, the dosage of each component of the premix is ​​as follows:

[0030] Magnesium sulfate monohydrate 2000g, potassium dihydrogen phosphate 400g, calcium dihydrogen phosphate 10000g, vitamin D3 20g, lysolecithin 200g, copper glycinate 100g, chromium methionine 200g, total 12920g.

[0031] The above-mentioned components are put into the mixer in descending order of consumption to form a premix, and then the premix is ​​added to the compound feed for Macrobrachium rosenbergii.

[0032] Using the above-mentioned feed formula, the Macrobrachium rosenbergii was fed with a full diet, and the Macrobrachium rosenbergii was divided into a test group and a control group (using conventional feed). The daily feeding amount (kg / 10,000 fish): 0.25-2.20, daily Feeding frequency: 4 times, feeding for 6 weeks. Macrobrachium rosenbergii ...

Abstract

The invention relates to a feed additive premix for preventing soft shell disease of macrobrachium rosenbergii. The weight percent of the premix in the macrobrachium rosenbergii formula feed is 1-3%, and on the basis of the addition amount in 1000kg macrobrachium rosenbergii formula feed, the premix comprises the following components by weight: 800-2000g of magnesium sulfate monohydrate, 400-1000g of potassium dihydrogen phosphate, 10000-20000g of calcium dihydrogen phosphate, 5-20g of vitamin D3, 200-1000g of lysoph-osphatidylcholine, 50-100g of copper glycinate, and 200-400g of methionine chromium. The problem that the magnesium sulfate monohydrate easily has soft shell disease during freshwater cultivation can be effectively solved by regulating the pH value in the feed and the hardness of water; trace elements which are insufficient in freshwater and easily cause the soft shell disease can be effectively supplemented, the formation of calcium and chitin in macrobrachium rosenbergii shells can be regulated, the thickness and hardness of the macrobrachium rosenbergii shells can be increased, and the synchronous shell removal can be promoted.

Description

technical field [0001] The invention relates to a shrimp feed, and more particularly to a feed formula for Macrobrachium rosenbergii. technical background [0002] Macrobrachium rosenbergii is native to the Indo-Pacific region and lives in various types of freshwater or brackish water. Since the 1960s, it has been transplanted to some countries and regions such as Asia, Europe, and America. It was introduced into China from Japan in 1976, and has been bred in more than 10 provinces (cities, districts) in the south, with Guangdong developing the fastest. Every 100 grams of shrimp meat contains 20.6 grams of protein, 0.7 grams of fat, and contains a variety of vitamins and trace elements necessary for the human body. It is a high-protein nutritional aquatic product and is favored by consumers. Macrobrachium rosenbergii is currently cultured in freshwater rivers and brackish waters. However, Macrobrachium rosenbergii cultured in fresh water tends to have soft shells and emacia...
