Journal ArticleDOI
An inhibitor persistently decreased enteric methane emission from dairy cows with no negative effect on milk production
Alexander N. Hristov,Joonpyo Oh,F. Giallongo,T. Frederick,M.T. Harper,H. L. Weeks,Antonio Ferriani Branco,Peter J. Moate,M. H. Deighton,S. Richard O. Williams,Maik Kindermann,Stephane Duval +11 more
TL;DR: The experiment demonstrated that the methane inhibitor 3NOP, applied at 40 to 80 mg/kg feed dry matter, decreased methane emissions from high-producing dairy cows by 30% and increased body weight gain without negatively affecting feed intake or milk production and composition.
Journal ArticleDOI
Mode of action uncovered for the specific reduction of methane emissions from ruminants by the small molecule 3-nitrooxypropanol
Evert C. Duin,Tristan Wagner,Seigo Shima,Divya Prakash,Bryan Cronin,David R. Yáñez-Ruiz,Stephane Duval,Robert Rümbeli,René Tobias Stemmler,Rudolf K. Thauer,Maik Kindermann +10 more
TL;DR: This study elucidates the development and the unique mode of action of the highly specific inhibitor 3-nitrooxypropanol (3-NOP), which is targeting the nickel enzyme methyl-coenzyme M reductase in rumen archaea that catalyzes the methane-forming reaction.
Journal ArticleDOI
Effects of 3-nitrooxypropanol on methane emission, digestion, and energy and nitrogen balance of lactating dairy cows
Christopher K. Reynolds,David J. Humphries,P. Kirton,Maik Kindermann,Stephane Duval,W. Steinberg +5 more
TL;DR: Changes in rumen concentrations of volatile fatty acids indicated that the pattern of rumen fermentation was affected by both doses of the product, with a decrease in acetate:propionate ratio observed, but that acetate production was inhibited by the higher dose.
Journal ArticleDOI
The effects of feeding 3-nitrooxypropanol on methane emissions and productivity of Holstein cows in mid lactation
J. Haisan,Y. Sun,Le Luo Guan,Karen A. Beauchemin,Alan D. Iwaasa,Stephane Duval,Daniel R. Barreda,Masahito Oba +7 more
TL;DR: The data showed that feeding 3-nitrooxypropanol to lactating dairy cows at 2,500 mg/d can reduce methane emissions without compromising DMI or milk production.
Journal ArticleDOI
Sustained reduction in methane production from long-term addition of 3-nitrooxypropanol to a beef cattle diet.
Atmir Romero-Pérez,Erasmus Okine,Sean M. McGinn,Le Luo Guan,Masahito Oba,Stephane Duval,Maik Kindermann,Karen A. Beauchemin +7 more
TL;DR: It is demonstrated that the addition of NOP to a diet for beef cattle caused a sustained decrease of methanogenesis, with no sign of adaptation, and that these effects were reversed once NOP addition was discontinued.
