Composite plant powder for minimizing methane output of rumen culture and preparation method thereof

Abstract

The invention relates to a preparation method of a composite plant powder for minimizing methane output of rumen culture. Garden balsam, Atractylodes lancea and Yedo violet which are dried to constant weight are crushed according to a certain proportion to prepare the composite plant powder. By the addition of 0.2%, 0.5% and 1.0% of the powder, the output of methane of rumen culture within 24 hours are respectively reduced by 83.62%, 96.89% and 98.67% in comparison with a control group. In comparison with the methane output in a monensin treatment group, the methane output by the addition of 0.5% and 1.0% of the powder is respectively reduced by 23.69% and 32.31%. In the meantime, the powder can also increase the output of total volatile aliphatic acid and reduce propionic/acetic acid ratio, and has a better effect than monensin. It shows through results that the composite plant powder has a substantial effect of reducing methane as well as performance for improving rumen fermentation, and can replace antibiotics to regulate and control rumen fermentation and control methane generation. Therefore, health and environmental problems derived from antibiotics can be effectively eliminated.

Description

Technical field: [0001] The invention relates to a preparation method of a compound plant powder which can reduce the methane output of rumen culture. Background technique: [0002] Methane (CH 4 ) of the greenhouse effect is carbon dioxide (CO 2 ), although the content of methane in the atmosphere is far lower than that of carbon dioxide, its contribution to global warming has reached 20%, second only to carbon dioxide (Moss A R, Jouany J P, Newbold J. Methane production by ruminants: contribution to global warming [J]. Annales De Zootechnie, 2000, 49(3): 231-253). The current methane emission is still growing at a rate of 1% per year, and its growth rate is twice that of carbon dioxide (Chen Chongyou, Li Zhiguo, Hu Yanfang, Sun Jin, Ji Chen. Carbon and nitrogen cycle and energy structure [J]. Ecological Environment 2008, 17 (2): 872-878), if not controlled, it is estimated that the contribution rate of methane to global warming will reach 50% by the middle of this centu...

Problems solved by technology

[0004] At present, the main method to control rumen methane production is to use antibiotics, such as monensin (Tedeschi LO, Fox D G and Tylutki T P. Potential environmental benefits of ionophores in ruminant diets[J]. J Environ.Qual, 2003, 32: 1591 -1602.; McGinn S M, Beauchemin K A, Coates T, et al. Methane emissions from beef cattle: Effects of monensin, sunflower oil, enzymes, yeast, and fumaric acid [J]. J Anim. Sci, 2004, 82: 3346 -3356.), although this method can reduce the methane production in the rumen to a certain extent, due to a series of health and environmental proble
