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

[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 problems such as drug residues, drug resistance and secondary pollution, it is subject to more and more strict restrictions in China, Internationally, such as the European Union, it has been explicitly banned (Regulation EC No 1831 / 2003 of the European Parliment and Council of 22 September 2003 on additives for use in animal nutrition[C].Official J.Eur.Commun.EC, 2003: L268 , 29-43.; Casewell M, Friis C, Marco E, McMullin P, Phillips I.
