Researchers at the Spanish National Research Council (CSIC) have taken part in a study of the effect of one molecule, 3-nitrooxypropanol, in inhibiting methane production in ruminants. The work has ...

Research led by a University of Wyoming graduate student involving about 50 scientists from across the globe has provided new insights into the behavior of ungulates (hoofed animals) as it relates to ...

Why does a kangaroo expel less methane than a cow? Researchers decided to investigate -- and discovered that the emission of this climate-damaging gas in kangaroos is linked to how long food is ...

The digestive systems of mammals exemplify a remarkable spectrum of adaptations that have evolved in tandem with dietary specialisations. These adaptations encompass both morphological ...
