Methane emissions from dairy cows fed grass or corn silage diets supplemented with rapeseed oil were evaluated. The partial replacement of GS with MS decreased the total dry matter (DM), nutrients intake, milk yields or nutrients digestibility, among others, but did not affect the daily CH4 emissions or strongly affect the microbial composition. The supplementation of rapeseed oil also decreased total DM, nutrients intake and altered the milk composition, but also decreased the CH4 emissions. Analysis of the microbial composition revealed an increase in the relative abundance of Methanobrevibacter and changes in the bacterial population.

The inclusion of maize silage and oilseeds in dairy products livestock diets has been reported, independently, to decrease enteric methane emissions. The aim of the research was to examine the impact of the partial substitute of turf silage with maize silage on milk manufacturing and CH4 emissions by milk cows fed diets with or without rapeseed oil supplementation. Twenty Nordic Red cows averaging 71 ± 37. 2 days in milk and 34. 2 ± 5. 26 kg milk/d pretrial were obstructed by parity and milk yield and assigned to a replicated 4 × 4 Latin square created with 4 28 d durations consisting of14 d of adaptation and 14 d of sampling and information recording. To conclude, the forage type did not change methane, but 4 g/kg DM of rapeseed oil in the diet plan to milk cows lowered CH4 emissions by 22. 5%.
