Lotta Rydhmer
I work with research and education on animal breeding and genetics, mainly breeding for sustainable production. I have performed many genetic studies of reproduction and behavioural traits, and relations between reproduction and production traits, especially in pigs.


  • Future Agriculture - livestock, crops and land use, an interdisciplinary research platform at SLU
  • Mistra Biotech – Biotechnology for sustainable and competitive agriculture and food systems
  • Breeding for sustainable pig production in various production systems
  • Genetics of maternal ability and oxytocin in sows
  • Entire male pigs, behaviour and management
