Finding key parameters for improved forage utilization and lowered methane emissions in dairy cows

| Type artikkel: Forskningsprosjekt
The aim of this project is to investigate individual differences in the rate of passage of feed, feed efficiency, microbial flora and methane production in cows with different ability to consume large proportion of roughage. Our previous studies show that methane production differs between cows with the same intake and that individual differences are greater than the effect of the diet.

This variation could make it possible to breed cows with lower methane production and more energy for milk production. However, it is important to identify the reasons for the difference, otherwise there is a risk of selecting cows that produce less methane due to of less digestion of feed. This study plans to use cows in an already funded project where the individual’s ability to utilize roughage is studied. We want to collect the data on methane production, microbial composition, passage rate and genetic markers for methane production in order to evaluate the potential for selection of efficient cows.
