Effects of marine and freshwater macroalgae on in vitro total gas and methane production.
TL;DR: The lack of relationship between the primary biochemistry of species and gas parameters suggests that significant decreases in TGP and CH4 production are associated with secondary metabolites produced by effective macroalgae, and Asparagopsis offers the most promising alternative for mitigation of enteric CH4 emissions.
Journal ArticleDOI
The red macroalgae Asparagopsis taxiformis is a potent natural antimethanogenic that reduces methane production during in vitro fermentation with rumen fluid
TL;DR: In vitro assessment method used here clearly demonstrated that Asparagopsis can inhibit methanogenesis at very low inclusion levels whereas the effect in vivo has yet to be confirmed.
Journal ArticleDOI
Asparagopsis taxiformis decreases enteric methane production from sheep.

TL;DR: While the outcomes of the present study may be extrapolated to feedlot to achieve the antimethanogenic effect associated with Asparagopsis, further work is required to define the long-term effects on productivity and animal health.
Journal ArticleDOI
Identification of bioactives from the red seaweed Asparagopsis taxiformis that promote antimethanogenic activity in vitro
Lorenna Machado,Marie Magnusson,Nicholas A. Paul,Robert D. Kinley,Rocky de Nys,Nigel W. Tomkins +5 more
TL;DR: In this paper, the main bioactive natural products and their effects on fermentation using rumen fluid from Bos indicus steers were tested and the dichloromethane extract was most active, reducing methane production by 79%.
Journal ArticleDOI
Dose-response effects of Asparagopsis taxiformis and Oedogonium sp. on in vitro fermentation and methane production
Lorenna Machado,Marie Magnusson,Nicholas A. Paul,Robert D. Kinley,Rocky de Nys,Nigel W. Tomkins +5 more
TL;DR: The effectiveness of Asparagopsis demonstrates its potential for the mitigation of methane emissions from ruminants at inclusion rates of ≤2 % OM, and Oedogonium is a potential feed supplement due to its nutritional value, but supplements ≤25 %OM are recommended to avoid adverse effects on apparent in vitro fermentation.
