Journal ArticleDOI
Supplementation with crushed rapeseed causes reduction of methane emissions from lactating dairy cows on pasture
T. M. Storlien,Egil Prestløkken,Karen A. Beauchemin,Tim A. McAllister,Alan D. Iwaasa,Odd Magne Harstad +5 more
TL;DR: In this paper, the authors investigated the effect of supplementing a pasture diet with crushed rapeseed on enteric methane (CH4) emissions from lactating dairy cows, and showed that adding crushed RSC to the diet can be an effective means of reducing CH4 emissions from dairy cows on pasture, without negatively affecting milk production.
Journal ArticleDOI
Combined effects of 3-nitrooxypropanol and canola oil supplementation on methane emissions, rumen fermentation and biohydrogenation, and total tract digestibility in beef cattle.

TL;DR: The individual and combined effects of 3-nitrooxypropanol (3-NOP) and canola oil (OIL) supplementation on enteric methane (CH4) and hydrogen (H2) emissions, rumen fermentation and biohydrogenation, and total tract nutrient digestibility were investigated in beef cattle as discussed by the authors.
Journal ArticleDOI
Effect of maturity at harvest on in vitro methane production from ensiled grass
L. Holtshausen,Silje Hanche-Olsen Liestøl,Silje Katrine Nes,Karen A. Beauchemin,Odd Magne Harstad,Tim A. McAllister +5 more
TL;DR: In this article, the authors evaluated the effect of the time of harvest on grass maturity in a mixed timothy (Phleum pretense)-meadow fescue (Festuca pratensis) stand.
Journal ArticleDOI
In vitro degradation of fresh substrates treated with exogenous fibrolytic enzymes
TL;DR: In this paper, an exogenous fibrolytic enzyme product was applied to three different proportions of a total mixed ration (TMR) and fed to dairy cows and no enhancement of the hydrolytic capacity of rumen f...
Journal ArticleDOI
Greenhouse gas and ammonia emissions from stored manure from beef cattle supplemented 3-nitrooxypropanol and monensin to reduce enteric methane emissions.
Jennifer Owens,Ben W. Thomas,Jessica L. Stoeckli,Karen A. Beauchemin,Tim A. McAllister,Francis J. Larney,Xiying Hao +6 more
TL;DR: This paper showed that 3-nitrooxypropanol (3-NOP) does not have residual effects on manure decomposition as estimated using total carbon and nitrogen losses and GHG emissions.
