Effects of different feed additives on methane emissions from beef cattle

摘要

The rate of accumulation of methane in the atmosphere from enteric fermentation in cattle has an important impact on the greenhouse effect and contributing to global warming. Additionally, methane emission reduces the energy efficiency of substrate fcrmcntion in the rumen. Understanding the effect of the diet on enteric methane emissions could help to identify strategics to reduce emissions of this greenhouse gas. Therefore, the main objective of the present investigation was to determine the effectof nutritional additives such as monensin, fumaric acid, tannins of Acacia decurrens, and glycerol on methane production and other measures of fermentation character-istics using the in vitro rumen fermentation technique and ruminal fluid obtained from cattle fed with a base diet of Pennisetum clandestinum.
