Embodiment 1

[0015] Example 1: 1527 liters of baker's yeast CGMCC NO.2.503 self-solution (containing 192.5 kg of dry matter) was sterilized at 90 degrees Celsius for 60 minutes, and then the enzyme residue was filtered with a 40-mesh sieve to obtain baker's yeast self-solution; then heptahydrate was added 148.5 kilograms of zinc sulfate, zinc sulfate heptahydrate is added while opening from solution with baker's yeast in the adding process, adjusts pH to 5.0, after carrying out chelation reaction at 60 degrees Celsius for 40 minutes, then warming up to 90 degrees Celsius for 60 minutes, Dried by a spray dryer (model GLZ, produced by Wuxi Xishan Spray Drying Equipment Manufacturing Plant), the outlet air temperature of spray drying is 80 degrees Celsius, and 275 kg of finished product is obtained.

Embodiment 2

[0016] Example 2: 3055 liters of brewer's yeast CCTCC NO.M93049 self-solution (containing 385 kilograms of dry matter) was sterilized at 90 degrees Celsius for 60 minutes, and then the enzyme residue was filtered with a 40-mesh sieve to obtain brewer's yeast self-solution; then heptahydrate was added 297 kilograms of zinc sulfate, zinc sulfate heptahydrate is added while opening from the solution with baker's yeast in the process of adding, adjust the pH to 5.0, carry out the chelation reaction at 65 degrees Celsius for 40 minutes, then heat up to 90 degrees Celsius for 60 minutes, Dried by a spray dryer (model GLZ, produced by Wuxi Xishan Spray Drying Equipment Manufacturing Factory), the outlet air temperature of spray drying is 85 degrees Celsius, and 550 kg of finished product is obtained.

[0017] Implementation: production of yeast iron chelate feed additive

Embodiment 3

[0018] Example 3: Sterilize 1462 liters of baker's yeast CGMCC NO.2.503 self-solution (containing 184.25 kilograms of dry matter) at 90 degrees Celsius for 60 minutes, then filter the enzyme residue with a 40-mesh sieve to obtain baker's yeast self-solution; then add heptahydrate 165 kilograms of ferrous sulfate, ferrous sulfate heptahydrate is added while dissolving from solution with baker's yeast in the process of adding, adjusts pH to 5.0, carries out chelation reaction 90 minutes at 70 degrees centigrade, through spray drier (model GLZ, Wuxi Xishan Spray Drying Equipment Manufactory produces) drying, and the outlet air temperature of spray drying is 90 degrees centigrade, obtains 275 kilograms of finished products.

Abstract

A feed additive containing yeast, trace element chelate and inorganic metallic salt is prepared through adding yeast and said inorganic salt, regulating pH value to 5, chelating reaction at 60-90 deg.C for 90 min, and spray drying. Its advantages are high biological utilization rate, high effect on improving immunity and quality of animal, high survival rate and high laying rate or weight increasing rate.

Description

technical field [0001] The invention relates to a production method of an animal feed additive, in particular to a feed additive containing a yeast trace element chelate and a production method thereof. Background technique [0002] Domestic feed trace element additives have developed from inorganic mineral additives to organic trace element additives. Compared with inorganic substances, the absorption rate of trace elements of amino acid chelate for feed has been greatly improved. Trace elements of inorganic salts, the total bioavailability is less than 20%. "China Feed" No. 21 report in 1999: According to radioisotope determination and LD-50 research, chelates have higher bioavailability and less toxicity than trace elements in inorganic salts, and the absorption of zinc lysine rate, 1.7-1.8 times higher than zinc sulfate, however, the absorption rate still hovers around 50%. At the same time, the composition is only one or several amino a...
