Abstract
The present invention provides the preparation method of a kind of cow feed additive, comprises the steps: 1) to choose sensitive bacteria, the Folium Bambusae of active component extraction rate reached to 8.3% is extract raw material；2) with 99.5% the ethanol extractant as Substance, controlling temperature is 65 degrees Celsius, and heating and refluxing extraction twice, feed liquid is respectively 1/10 and 1/5, controls each reflux extracting time and is respectively 2h, 1h；3) Extracting temperature controlling extracting solution is 65 degrees Celsius, obtains paste thickness extract after concentration；4) extract step 3) obtained dissolves with diluent according to the volume ratio of 1:80, dilutes, and keeps being sufficiently stirred under 45 degrees Celsius；5) under 55 degrees Celsius, it is dried to obtain powder additive.The preparation method of a kind of cow feed additive that the present invention provides, technique is simple, with low cost.
Description
Technical field
The present invention relates to domestic animal cultural technique field, particularly relate to the preparation method of a kind of cow feed additive.
Background technology
In recent years, China's animal husbandry grows continuously and fast, and wherein, feedstuff is increasingly becoming great the asking affecting China's agricultural
Topic.In recent years, in countries such as aquaculture prosperity Britain, Denmark, Switzerland, France, owing to using animal protein feed (meat in large quantities
Bone meal), cause the animal genetic diseasess such as bovine spongiform encephalopathy to jeopardize the development of aquaculture, many domestic animals are butchered, are burned, and then
Cause the mankind that food-safety problem is filled with huge fear and uneasiness.
Summary of the invention
For solving the problems referred to above present in prior art and practical situation, the present invention provides a kind of cow feed additive
Preparation method, comprise the steps:
1) choosing sensitive bacteria, the Folium Bambusae of active component extraction rate reached to 8.3% is extract raw material；
2) with 99.5% the ethanol extractant as Substance, controlling temperature is 65 degrees Celsius, heating and refluxing extraction two
Secondary, feed liquid is respectively 1/10 and 1/5, controls each reflux extracting time and is respectively 2h, 1h；
3) Extracting temperature controlling extracting solution is 65 degrees Celsius, obtains paste thickness extract after concentration；
4) extract step 3) obtained dissolves with diluent according to the volume ratio of 1:80, dilutes, and keeps under 45 degrees Celsius
It is sufficiently stirred for；
5) under 55 degrees Celsius, it is dried to obtain powder additive.
Beneficial effect:
The preparation method of a kind of cow feed additive that the present invention provides, technique is simple, with low cost, experimental results demonstrate,
The cow feed additive containing natural bamboo that the preparation method of a kind of cow feed additive that the present invention provides prepares, when it
When bringing up to 45g/d, it is remarkably improved the fat corrected milk yield of milch cow 3.8%, improves milch cow physiological situation, reduce the ill several of milch cow
Rate.
Detailed description of the invention
Technical solution of the present invention is described in detail below.
