Switzerland: research on methane and ammonia emissions by cows

In Switzerland research by Agroscope shows that Esparsette or Sainfoin (Onobrychis viciifolia) can reduce methane and ammonia emissions by cows. Freshly fed sainfoin had a methane-reducing effect in dairy cows compared to grass-clover, with no effect on milk yield. Relative to the intake, a larger part of the N excretion takes place in the faeces and not in the urine when sainfoin is fed, which can have a positive effect on the potential ammonia emission.
