Genomisk prediksjon av laktasjonskurver for metan og produksjonseffektivitet hos Norsk Rødt Fe

Offentlig prosjektsammendrag

This project will enable targeted genomic selection to reduce methane emissions and improve production efficiency in Norwegian Red dairy cattle. To achieve this, the project will utilize daily records of methane output, feed intake, milk yield, and body weight from selected herds to model lactation curves. These curves will form the basis for estimating breeding values for both trait levels and curve shapes. By applying multi-trait models and integrating pedigree and genomic data, breeding values will be estimated across the entire population and incorporated into the overall breeding value, which is the main criterion used for selecting breeding animals. This approach enables systematic selection of animals that are both more climate-friendly and efficient, driving genetic progress toward a more sustainable and resilient dairy sector.
