Four multiparous cows (two 2nd parity and two 3rd parity), which had previously been fitted with rumen, duodenal, and ileal cannulas for the collection of digesta, were used. At the beginning of the experiment, average ± SD milk yield was 33.1 ± 2.10 kg/day, days in milk w...
However, the cryogenic technology has not been used for the enrichment from low CH4 concentrations as present in coalmines or in the barn of dairy cows. Therefore, the aim of the present study was to construct a technical test rig with which enteric CH4 released from dairy cows can be ...
Oribacterium has been identified as one of the primary bacteria in the rumen of cows fed with forage [37, 38]. However, current research on this bacterium is still limited, with existing studies merely speculating a relationship between ruminal Oribacterium and the production of alanine [39]. ...
Total collection of feces and urine over 3 d was performed on 8 cows (1 Latin square from each breed). The difference in dry matter intake (DMI) between Holsteins and Jerseys was greater when fed AS than CS. Compared with Jerseys, Holstein cows had greater body weight (48%), DMI (34...
New data from a fracking site in Blackpool has revealed the extent of the industry’s environmental footprint, with researchers tracing a huge 4. Click to read more...
Further, the research advances towards CH4 emissions mitigation are summarized from a collection of selected scholarly articles, as there is currently no exact consensus and regulation on CH4 mitigation. The primary objective of presenting these contributions through our study is to deepen the ...
Methane is the main component in natural gas, which is used to generate electricity and heat homes around the world. Here's why it's a big deal.
Methanomassiliicoccales are a recently identified order of methanogens that are diverse across global environments particularly the gastrointestinal tracts of animals; however, their metabolic capacities are defined via a limited number of cultured strai
seedlings were separated at the rhizome to ascertain the fresh weight of both shoot and root. To determine the biomass (dry weight), fresh samples were dried to a constant weight at 65 ℃ for 48 h. This meticulous monitoring and measurement process ensured accurate data collection for subsequent...
Tubes were administered to all cows in April, 136 d before the first measurement period. To ensure reliability of gas sampling during grazing, indoor housing, and milking, gas collection canisters were fitted on the back of each cow using a proprietary saddle apparatus, described by O’Neill ...
