A sheep looks out from a portable accumulation chamber where Emily Roskam, a PhD Walsh Scholar at Teagasc, measures the methane emissions of the sheep, after it spends an hour in the methane measuring chamber at the end of a Seasolutions trial at the Teagasc Agriculture and Food Development Authority in it's Mellows Campus in Athenry, Ireland, September 6, 2021. During the Seasolutions trial, sheep were fed seaweed extract to reduce their methane emissions. "We have 140 sheep here and each morning they are getting half a kilo of concentrates, they get 400 grams of nuts made of maize meal and a bit of molasses which is kind of sugary to stick them together, then they each get 100grams of their additives, we have a 'control diet' or we have seaweed extract," said Roskam.
