Embodiment 1

[0036] Embodiment 1, the preparation of silage additive

[0037] Weigh 25g of Radix Astragali, soak in 250mL deionized water for 30min, decoct, boil and decoct for 30min, use 4 layers of gauze with a pore size of 1mm to filter for the first time to obtain the first filtrate and medicinal residues, add 150ml of medicinal residues to the medicinal residues Water, after decocting with slow fire for 30min, carry out second filtration, after the second filtrate of gained is combined with first time filtrate, decoct with slow fire and concentrate to 25ml, make its solid content be 1g / ml, be 100% Chinese herbal medicine stoste, The 100% traditional Chinese medicine stock solution is the extract of Radix Astragali.

[0038] According to the same method as above, the astragalus is replaced by hawthorn to obtain the hawthorn extract.

[0039] The above-mentioned astragalus extract and hawthorn extract are mixed together at mass ratios of 0.75:0.75, 1:1 and 1.25:1.25 respectively to obt...

Abstract

The invention discloses a silage additive and a preparation method and application of the silage additive. The active ingredient of the silage additive is a composition of (a) or (b) as follows: a composition consisting of an extract of radix astragali and an extract of fructus crataegi; and the two extracts are mixed together or separately packed. The prepared silage has at least one of the following characteristics: (1) the content of crude protein is higher than that in the control group; (2) the ratio of ammoniacal nitrogen to silage additive is lower than that in the control group; (3) the content of neutral detergent fiber is lower than that in the control group; (4) the content of acid detergent fiber is lower than that in the control group; (5) the pH value is lower than that in the control group; and (6) the content of lactic acid is higher than that in the control group, and the content of butyric acid is lower than that in the control group.

Description

technical field [0001] The invention relates to a Chinese herbal medicine type silage biological additive and its application, in particular to a silage additive and its preparation method and application. Background technique [0002] The digestibility of silage is higher than that of similar silage directly used or made into hay, and the digestible crude protein, total nutrient and energy content in the dry matter of silage are also higher, and the digestibility of cell wall components of silage after silage fermentation will also increase. Significantly improved. However, in the natural state, the buffer value of green fodder is high, and the content of soluble carbohydrates is low, so it is difficult to silage in the natural state. This phenomenon is especially obvious in leguminous pastures. Silage additives can speed up the fermentation of silage and improve the quality of silage. In recent years, the types of silage additives at home and abroad mainly include ammoni...
