Research

My research area covers nutrition and physiology of cattle with focus on animal production, nutrient utilization, nutrient excretion and impact of animal production on climate and environment. The research activities include:

• Nutrition and feeding strategies which support a high productivity and a low environmental impact of dairy cows

• Feeding strategies for dairy cows with low content of roughage
• Effect of diet on methane emission

I have a major task in giving scientifically based advice to authorities (Myndgihedsberedskab) about effects of livestock production on climate and environment. I also teach in courses for bachelor and master students about effects of livestock production on climate and environment.
