Embodiment Construction

[0010] specific implementation plan

[0011] The bacterial strain used in the present invention, Rhodotorula viscosus CICC32881, was purchased from China Industrial Microorganism Culture Collection and Management Center.

[0012] (1) Preparation of liquid seeds of Rhodotorula viscosus:

[0013] Take 100 ml of 12Bx wort and culture it in a 500 ml Erlenmeyer flask, sterilize it at 121°C for 20 minutes, cool it down to 28°C, inoculate a ring of Rhodotorula viscosus from the slope, and cultivate it at 28°C and 150rpm on a rotary shaker for 24 Hour.

[0014] (2) Production of salmon feed additives:

[0015] Weigh 100 grams of cornmeal, put it in a triangular flask, add 300ml of water, shake well, add 0.2 grams of calcium chloride, add high-temperature-resistant α-amylase at a rate of 10 to 12 units per gram of cornmeal, and heat it at 90 to 95°C Keep warm for 30 minutes, cool to 60°C, adjust the pH to 4.5, add glucoamylase at a rate of 100 units per gram of cornmeal, maintain sa...

Abstract

The invention provides a feed additive production method, especially a salmon feed additive production method, and relates to a feed additive production method, particularly to a salmon feed additive production method. The production method comprises: weighing silkworm pupa powder and fish meal, adding a corn meal saccharification liquid, uniformly mixing, sterilizing, cooling to a temperature of 28 DEG C, inoculating Rhodotorula glutinis liquid seed, placing into a constant temperature oven to culture for 72 h, and carrying out drying, crushing and granulation to obtain the finished product. The salmon feed additive contains a large amount of astaxanthin produced during a Rhodotorula glutinis fermentation process, such that the salmon can uptake the salmon feed additive to obtain the astaxanthin so as to achieve meat color increase, salmon immunity can be improved, and fish disease occurrence can be prevented. During feeding of the salmon, the salmon feed additive is added to a salmon complete formula feed according to a ratio of 10%, and uniform mixing is performed to obtain the finished product.

Description

technical field [0001] The invention relates to a preparation method of a feed additive, in particular to a preparation method of a salmon feed additive. Background technique [0002] Salmon (salmon) is also called Salmon fish or Salmon fish, and its scientific name is salmon. It is mainly distributed in the northern part of the Pacific Ocean and the northern regions of Europe, Asia and America. Salmon is one of the rare fishes in the world. It has few scales and thorns, orange-red meat, tender and delicious meat, and smooth taste. It can be eaten raw or cooked. It is a fish that is deeply loved by people. Salmon is rich in unsaturated fatty acids, which can effectively reduce blood fat and blood cholesterol and prevent cardiovascular diseases. Salmon also contains a substance called astaxanthin, which is a very powerful antioxidant. In addition, the omega-3 fatty acids contained in it are essential substances for the brain, retina and nervous system, which can enhance brai...
