• Can Rumen Cannulation Alter Ruminal Dissolved Gases and Methanogen Community in Dairy Cows?

  Researchers from China Agricultural University, the Institute of Subtropical Agriculture (ISA) of Chinese Academy of Sciences investigated the effects of rumen cannulation on ruminal dissolved gases and methanogenesis.Four cows were surgically fitted with rumen cannula, while the other four cows were left intact and used as control. Rumen gases and contents were collected 0, +2.5 and +6 h relative to the commencement of the morning feeding on d 41 and 42.
