About the project

This innovation project is owned by Geno

The main aim of this project is to find how we best can reduce the environmental footprint of Norwegian dairy production by breeding. Before a new trait, like methane emission, can be considered included in the breeding goal, research is needed to estimate genetic variation and validate how accurately we can predict the genetic merit of the animals. For this we need measures of methane production for individual Norwegian Red (NR) cows. GreenFeed (www.c-lockinc.com) units for monitoring methane emissions have been installed in 14 selected herds. All cows in these herds are genotyped.

Methane data together with data from the herd’s automatic milking system are now collected routinely to Geno’s database. Establishing data collection and routines for data editing and quality control was the first important milestone in the project. Results so far indicate that there is substantial genetic variation for methane emission in the Norwegian Red breed, and breeding for lower methane is feasible. Further research will focus on developing predictions for methane emissions, estimating genetic associations to other important traits, and examining which trait definitions for methane emissions would be better for successful implementation in the breeding program.

  • Objectives

    The main aim is to find the best strategy to reduce the environmental footprint of Norwegian dairy production by breeding.

    More specifically we will:

    • Establish direct phenotyping of methane emission for individual cows
    • Estimate heritability of methane emission for the Norwegian Red (NR) breed
    • Predict methane from data on mid-infrared spectra in milk
    • Validate the accuracy of genomic predicted breeding values for methane emission in NR
    • Estimate genetic correlations between methane production and important traits in the NR breeding goal
