Background
Rumen methanogenesis is the single most significant source of anthropogenic methane (CH4) emissions. This research aimed to analyse CH4 data recorded by GreenFeed systems by assessing the repeatability of such phenotypic measures, estimating the heritability of CH4, and generating CH4 estimated breeding values (EBVs) for inclusion in the national breeding index.
Methods
CH4 measurements were recorded on 979 cattle for 20 to 83 days using GreenFeed machines, resulting in 211,136 individual CH4 observations. The phenotypic repeatability of CH4 was estimated for six different averaging periods using a linear mixed …
