Iodoform has shown potential in reducing methane emissions when included in the diet of dairy cows, presenting a promising solution for decreasing greenhouse gas emissions from livestock systems. During her PhD studies, Marie Rønn investigated the possible impacts of using this compound as a feed additive, both on cows themselves and the consumer of dairy milk. The results were obtained from research experiments conducted in the barn, in the laboratory, and with cell culture studies. This research provided new insights into the absorption, distribution, metabolism, and excretion pathways of iodoform in dairy cows, which were crucial for validating the safety of its potential future use as a methane-mitigating feed additive.

The PhD study was completed at Department of Animal and Veterinary Sciences, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
