Monogastric nutrition and physiology

Our research aim and focus

The theme group aims to improve performance (growth and/or lactation), dietary composition and utilization of dietary nutrients to achieve sustainable animal production.    

Our primary focus areas

  • Nutrition, production and reproduction. In depth understanding of how ingested nutrients (fibers, digestible carbohydrates, protein, fat, energy, minerals and vitamins) are being metabolized and utilized for production and reproduction.
  • Precision/optimal feeding. Improve nutrition during transition periods (e.g. around farrowing and weaning). Individual feeding of animals to improve feed efficiency for growth and lactation performance and reduce excretion of nutrients. Phase-feeding and 2-component feeding strategies.
  • Quantitative Nutrition and physiology. Physiological requirements of nutrients. Ileal digestibility, flux of nutrients between and across organs (e.g. gastrointestinal tract, liver, and mammary gland) using surgically modified animals. Secretion of nutrients into milk, excretion of nutrients into urine and feces.
  • Biomarkers. Screen biological fluids for potential biomarkers and implementing them in experiments.
  • Organic animal production. Knowledge transfer from conventional production systems to less intensive breeds and/or less intensive production systems.
  • Digestion of feed, ingredients and nutrients and feed evaluation.

Our research perspectives

Nutrition is highly important for sustainable production as feed cost is the major expense for animal production.

It is important to understand how feed -intake, -ingredients, -composition, -additives, processing of feed and meal frequency interact with management and intrinsic animal factors to ensure high productivity and healthy animals.
