Embodiment 1

[0020] Preparation of feed additives:

[0021] Composition (according to mass fraction): 30% rehmannia glutinosa powder, 5% polyvinylpyrrolidone k30, 50% iron glycinate, 5% vitamin C, 0.5% selenomethionine, and 100% medical stone.

[0022] Preparation method: mix rehmannia glutinosa and medical stone, and pass through a 80-mesh sieve. The pulverized rehmannia glutinosa and medical stone are spray-coated in a fluidized bed with an ethanol solution of polyvinylpyrrolidone k30, and the solid content of the spray solution is 10% (w / w). The obtained coating material is powder in granular state and can completely pass through a 65-mesh sieve. The coating material is uniformly mixed with iron glycinate, vitamin C and selenomethionine to obtain a feed additive.

[0023] In the above preparation method, the parameters of the fluidized bed are as follows: fan frequency 14Hz, material temperature 38°C, air inlet temperature 53°C, atomization pressure 0.10MPa, liquid supply speed 2.0rpm...

Embodiment 2

[0025] Preparation of feed additives:

[0026] Composition (according to mass fraction): 20% rehmannia glutinosa powder, 3.5% poloxamer 188, 30% iron glycinate, 3% vitamin C, 0.3% selenomethionine, and 100% kaolin.

[0027] Preparation method: mix rehmannia glutinosa and kaolin clay, and pass through a 80-mesh sieve. The pulverized rehmannia glutinosa and medical stone were spray-coated in a fluidized bed with ethanol solution of poloxamer 188, and the solid content of the spray solution was 10% (w / w). The obtained coating material is powder in granular state and can completely pass through a 65-mesh sieve. The coating material iron glycinate, vitamin C and selenomethionine are evenly mixed to obtain the feed additive.

[0028] In the above preparation method, the fluidized bed parameters are as follows: fan frequency 11Hz, material temperature 35°C, air inlet temperature 50°C, atomization pressure 0.08MPa, liquid supply speed 1.5rpm, fluidized bed drying for 30min after coa...

Embodiment 3

[0030] Preparation of feed additives:

[0031] Prescription (according to mass fraction): Rehmannia glutinosa powder 10%, sodium carboxymethylcellulose 1.5%, iron glycinate 15%, vitamin C 1.5%, selenomethionine 0.15%, zeolite powder to 100%.

[0032] Preparation method: mix rehmannia glutinosa and zeolite powder, and pass through a 80-mesh sieve. The pulverized product of rehmannia glutinosa and medical stone is spray-coated in a fluidized bed with ethanol solution of sodium carboxymethyl cellulose, and the solid content of the spray solution is 10% (w / w). The obtained coating material is powder in granular state and can completely pass through a 65-mesh sieve. The coating material iron glycinate, vitamin C and selenomethionine are evenly mixed to obtain the feed additive.

[0033] In the above preparation method, the parameters of the fluidized bed are as follows: fan frequency 14Hz, material temperature 40°C, air inlet temperature 55°C, atomization pressure 0.10MPa, liquid...

Abstract

The invention discloses a feed additive for replenishing blood and a preparation method thereof, and belongs to the technical field of pharmaceutical preparations. The feed additive is prepared from the following components in percentage by mass: 10 to 30 percent of radix rehmanniae praeparata powder, 1.5 to 5 percent of a protective agent, 15 to 50 percent of glycine iron, 1.5 to 5 percent of vitamin C, 0.15 to 0.5 percent of selenomethionine and the balance of auxiliary materials. The feed additive disclosed by the invention is high in content of prepared rehmannia root and glycine iron, strong in blood replenishing effect, good in stability, free of color change and caking after being placed for a long time, and stable in component content.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a feed additive for enriching blood and a preparation method thereof. Background technique [0002] Iron glycinate is one of the most commonly used third-generation iron supplement preparations. The chelation of glycine and ferrous iron increases the stability of ferrous ions; iron glycinate is mainly actively absorbed by the intestinal tract of animals in the form of small peptides, and the absorption efficiency is high. Iron glycinate has good compatibility, is not affected by phytic acid and oxalic acid in the feed, will not destroy other nutrients and will not affect the absorption of other nutrients. Iron glycinate can also promote the growth and development of animals, make animal skin ruddy, coat shiny, and improve feed utilization. [0003] Rehmannia glutinosa is a commonly used traditional Chinese medicine for nourishing blood. It is swee...
