Genome-Wide Association Analysis of Pathologies in Piglets of Landrace and Large White Breeds

A genome-wide association study is conducted to identify gene polymorphisms in pigs associated with common pathologies in young animals. The genomes of 97 pigs (Landrace and Large White breeds) are sequenced, followed by genome-wide association analysis to identify possible markers of potentially heritable defects (malnutrition, gastroenteritis, scrotal hernia and cryptorchidism, tremors at birth). Polymorphisms are found in various genes, including those associated with development of the nervous system and the formation of neurological diseases, even in the case of pathologies not directly related to the functions of the nervous system.
