Problems solved by technology

[0006] The invention provides a method for preparing silage extract solution, which solves the problem that the traditional method for preparing silage extract solution in the laboratory in the prior art cannot effectively extract the fermented components in the silage feed, resulting in inaccurate data obtained in the final test. Accurate, and thus can not reflect the real fermentation quality of silage, and also solve the problem that the traditional silage extraction method in the laboratory needs to consume a lot of manpower, material resources and time, thus greatly wasting laboratory resources

Abstract

The Invention discloses a preparation method of silage leach liquor, which is particularly practiced by mixing and immersing sterilized distilling water with silage; performing sonic oscillation afterlow-concentration hydrochloric acid treatment; filtering by a filter membrane, wherein the filter fluid is the silage leach liquor. Besides, the invention further provides an application of silage leach liquor prepared by the preparation method in the silage detection. Diluted hydrochloric acid with 1% of mass concentration is added during the preparation process of silage leach liquor; on the one hand, the low-concentration diluted hydrochloric acid can promote the complete dissolution of fermenting indexes in the silage such as organic acid and ammoniacal nitrogen; on the other hand, the viscosity between the silages is weakened after being treated by hydrochloric acid, the solid and fluid can be separated rapidly in the process of filtering by adopting the filter membrane, thereby greatly shortening the experimental operation time and saving labor force and lab consumables.

Description

technical field [0001] The invention belongs to the technical field of forage silage detection, and in particular relates to a method for preparing silage extract and its application in silage detection. Background technique [0002] Silage is a commonly used feed, which is made of plant feed with high moisture content after sealing and fermenting, and is mainly used to feed ruminants. Silage is more resistant to storage than fresh feed, and its nutritional content is stronger than dry feed. Plus, silage storage takes up less land and has no fire problems. [0003] The pH value, organic acid, and ammoniacal nitrogen in silage are important technical indicators for evaluating the fermentation quality of silage. In order to detect these indicators, it is necessary to extract the silage to obtain an extract, which is reflected by testing the relevant indicators in the extract. Silage performance. [0004] The preparation method of the traditional silage extract in the labora...
