Abatement of Methane Production from Ruminants: Trends in the Manipulation of Rumen Fermentation

摘要: Methane emitted from ruminant livestock is regarded as a loss of feed energy and also contributor to global warming. synthesized in the rumen one hydrogen sink products that are unavoidable for efficient succession anaerobic microbial fermentation. Various attempts have been made reduce methane emission, mainly through manipulation, by use agents including chemicals, antibiotics natural such oils, fatty acids plant extracts. A newer approach development vaccines against methanogenic bacteria. While ionophore widely used due their efficacy affordable prices, alternative materials becoming more attractive health concerns regarding antibiotics. An important feature material constitutes possible inhibitor does not intake or digestibility but enhance propionate major methane. Some implications these approaches, well an introduction antibiotic-alternative novel provided.
