Embodiment 1

[0030] After the culture solution containing sugar and inorganic salt is sterilized, Escherichia coli is inoculated, fermented, and sugar and ammonia are supplemented during the fermentation process. Obtain tryptophan fermented liquid after fermentation, wherein sugar content is 0.1~1‰ (weight), thalline is 7~8% (weight), tryptophan 2~5% (weight), inorganic salt 1‰ ( weight), and the rest is water.

[0031] A thin-film evaporator is used to heat and stir the tryptophan fermentation broth to evaporate. Concentrating the tryptophan fermentation broth to a tryptophan content of 8% to obtain a concentrated feed solution. Take unexposed corncobs, air-dry them at 50 degrees Celsius until the water content is 20%, and then use a hammer mill to crush the corncobs into small particles with a particle size of about 80 mesh. Before adding the corn cob granules to the concentrated feed liquid, add feed-grade calcium carbonate, silicon dioxide, and sodium chloride to the concentrated fee...

Embodiment 2

[0038] The difference between the second embodiment and the first embodiment is that the concentration of the tryptophan fermentation broth is concentrated to a tryptophan content of 15% to obtain a concentrated feed liquid. Take unexposed corncobs, air-dry them at 60 degrees Celsius until the water content is 15%, and then use a hammer mill to crush the corncobs into small particles with a particle size of about 20 mesh. Before adding the corn cob granules to the concentrated feed liquid, add feed grade calcium carbonate and sodium chloride to the concentrated feed liquid in a stirring state, continue stirring for 3 minutes, and then add the corn cob granules to the concentrated feed liquid in a stirring state Feed liquid, the addition amount of corncob particle is 1 times of the weight of concentrated feed liquid. The inorganic carrier accounts for 2% of the whole premixed feed. The wet mixture is dried by the airflow drying method. After drying, the content of tryptophan i...

Embodiment 3

[0046] The difference between the third embodiment and the first embodiment is that the concentration of the tryptophan mother liquor is concentrated to a tryptophan content of 10% to obtain a concentrated feed solution. Take unexposed corncobs, air-dry them at 60 degrees Celsius until the water content is 15%, and then use a hammer mill to crush the corncobs into small particles with a particle size of about 30 mesh. Before adding the corn cob particles to the concentrated feed liquid, add feed grade calcium carbonate to the concentrated feed liquid in a stirring state, continue stirring for 2 minutes, and then add the corn cob particles to the concentrated feed liquid in a stirring state, corn The addition amount of the core particle is 0.7 times of the weight of the concentrated feed liquid. The inorganic carrier accounts for 0.5% of the whole premixed feed. The wet mixture is dried by the air-flow drying method. After drying, the content of tryptophan is about 10%, and th...

Abstract

The invention belongs to the feed technical field, in particular to an additive premixing feed. A processing method of the additive premixing feed comprises the following steps: (1) concentrating: fermenting feed liquid containing tryptophan is concentrated to obtain concentrated feed liquid containing 8%-15% tryptophan; (2) crushing: corn cob is crushed to obtain corm cob particles with 20-80 meshes; (3) mixing; the corn cob particles are added into the concentrated feed liquid in the stirring state to obtain wet mixed feed containing 5%-10% tryptophan; (4) drying: the wet mixed feed is dried. The additive premixing feed has better feeding effect.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to an additive premixed feed. Background technique [0002] Additive premixed feed is an intermediate compound feed product made by mixing one or more trace components with carriers or diluents according to requirements and uniformly mixing them. Trace components include various trace mineral elements, various vitamins, synthetic amino acids and other additives. Carriers are particles capable of carrying or adsorbing trace amounts of active additives. [0003] The invention with the application number 200810155198.5 published on March 18, 2009 discloses a special feed additive for laying hens during the laying period. The vitamin E, auxiliary materials medical stone and corncob powder are prepared by mixing according to the proportion, and the feed is helpful for the growth of animals. [0004] But the cost of above-mentioned feed is high, and the raising effect of the feed of unit ...
