Natural product preparation capable of reducing methane production amount of rumen microorganisms

Abstract

The invention relates to the field of rumen regulation, in particular to a natural product preparation capable of reducing methane production amount of rumen microorganisms. The natural production preparation is dried powder prepared by smashing fruits of fructus viticis, extracting the smashed fruits through ethanol solution with weight percentage of 60%-80% and performing nitrogen blowing, freezing and drying on the extracted product. The natural product preparation can obviously reduce the methane production amount of the rumen microorganisms. The invention further provides a preparation process of the natural product preparation and an application of the natural product preparation for reducing the methane production amount of the rumen microorganisms. Effective components like volatile oil of the fructus viticis can be extracted through ethanol, and the natural product preparation which is dried powder can be prepared through nitrogen blowing, freezing and drying. According to in-vitro fermentation test of rumens, 0.4g / L of the preparation, namely adding 40mg of the natural product preparation in each gram of dry matter, the methane production amount of the rumen microorganisms can be effectively reduced to 21.7%.

Description

technical field [0001] The invention relates to the field of rumen regulation, in particular to a natural product preparation for reducing the methane production of rumen microorganisms. Background technique [0002] Roughage is the main source of feed for ruminants, and the degradation of various fibrous substances in roughage is undoubtedly the most important digestive process that occurs in the rumen. This process produces a large amount of hydrogen. If hydrogen accumulates, it will inhibit the hydrogenation of reduced nicotinamide adenine dinucleotide, resulting in the accumulation of reductive fermentation products such as lactic acid (Wolin et al., 1997), which in turn hinders the digestion of roughage and beneficial microorganisms. growth is hindered. The generation of methane is the main way of hydrogen excretion in the rumen. During the ruminal metabolism of ruminants, about 2%-15% of the feed can be lost in the form of methane, depending on the feeding level, die...
