Ekesbo carried out from 1960 a research project to analyse with epidemiological methods the effect on animal health by different environmental and management factors. This meant that farm animal epidemiology was introduced at the Vet. College The projects later carried out by him and his research group were the beginning of modern animal hygiene, epidemiology, farm animal ethology and animal welfare research in Sweden. The staff have always kept a close connection to veterinary practice, through which many clinical problems which have arisen parallel with the radical changes in animal husbandry have been early scientifically elucidated. At the same time ethological methods were elaborated and put into practise.
His and his staff´s commitment to ethological and animal welfare research led to the establishment of a chair in farm animal ethology and one in animal welfare at his department.
Under the supervision of Ekesbo a number of PhD and licentiate's dissertations have been published.
Ekesbo has published more than 200 scientific and great number popular scientific papers within the fields of animal hygiene, epidemiology, ethology and ethics in animal husbandry. He has written a Swedish textbook on Animal hygiene which came out in nine editions. In 2011 he published the textbook "Farm animal behaviour – characteristics for assessment of health and welfare". A revised edition will be published in 2018 together with prof. S. Gunnarsson.
