Erling Strandberg

Erling Strandberg
Professor in animal breeding and genetics


My research mainly concerns the genetics of behavior in dogs, dairy cattle genetics and some studies related to developing countries.


I am mainly teaching in the course Animal Genetics - Health, behaviour and welfare and in our introductory breeding courses


I have been involved in several projects that have been aimed at quantifying the amount of genetic variation (and covariation) in various types of traits in various species. The traits studied have been fertility, health, behavior, maternal ability, performance or production, and longevity; and the species dairy cattle, pigs, poultry, horses, and dogs.


• Professor in animal breeding and genetics, SLU, 2003

  • Use of cow genotyping to improve genetic progress, farm profit and food production in Sweden (industry PhD student Christian Bengtsson, VikingGenetics)
  • Crossbreeding in dairy cattle: novel breeding tools for sustainable dairy and beef production - Julie Brastrup Clasen

Recently finished PhD-student projects
