Embodiment 1

[0035] Embodiment 1, Astragalus extract is used as silage additive to prepare red bean grass silage

[0036] 1. Preparation of silage additives

[0037] Take 20g (dry weight) of the traditional Chinese medicine Astragalus, add 100g of water, soak in the liquid surface of the Chinese medicine, place it in a refrigerator at 4°C for 24 hours, boil it with a simmer for 30 minutes, filter it, add 100g water, boil it with a simmer for 30 minutes, and filter it again. The medicinal liquids filtered twice are mixed and concentrated to 20 ml on a slow fire to obtain 100% traditional Chinese medicine stock solution, which is the silage additive.

[0038] 2. Effect of silage additives on the growth of lactic acid bacteria

[0039] Qingbao II natural lactic acid bacteria feed additive (Shaanxi Zhongrui Biological Co., Ltd. (2005) Waikai Zhunzi No. 096) was used as the lactic acid bacteria for the test. The experimental medium is MRS liquid and solid medium. Inoculate Qingbao II natural...

Abstract

The invention discloses Astragalus membranaceus serving as silage additive and application of Astragalus membranaceus in silage preparation. A method for preparing the silage, provided by the invention, comprises the following steps: adding Astragalus membranaceus and/or Astragalus membranaceus extract in silage raw materials, performing anaerobic fermentation to obtain the silage, wherein the Astragalus membranaceus extract is water-soluble matter extracted from Astragalus membranaceus with water. The silage prepared by the method of the invention has at least one of the following characteristics that: (1) crude protein content is higher than a control silage; (2) ratio of ammonia nitrogen to total nitrogen is lower than the control silage; (3) neutral detergent fiber content is lower than the control silage; (4) acid detergent fiber content is lower than the control silage; and (5) pH value is lower than the control silage.

Description

technical field [0001] The invention relates to a Chinese herbal medicine type silage biological additive and its application, in particular to astragali as a silage additive and its application in preparing silage. Background technique [0002] Silage is an effective and economical measure to solve the problem of difficult storage of silage. 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. For this reason, both at home and abroad are studying how to use additives to improve the quality of silage and accelerate the fermentation speed of silage. In recent years, scholars at home and abroad have done a lot of research on silage additives. From the perspective of single additives, there are mainly ammonium compounds, organic acids, urea, and biological preservatives. These additives all have the effect of inhibiting microbial activities. , and improve th...
