Abstract excerpt
This study aimed to quantify the effect of the methane-mitigating feed additive 3-nitrooxypropanol (3-NOP) on genetic parameters and potential genotype by environment (G × E) interaction for gas emission traits, that is, methane (CH4) and carbon dioxide (CO2) breath concentrations, as well as milk production traits in Danish Holstein cows. Weekly gas emission phenotypes on individual cow level, recorded with...
