摘要

Mastitis, one of the most common diseases in dairy cattle, causes huge economic losses. The disease occurs due to intramammary infection (IMI) caused by several pathogenic bacteria. A group of minor pathogens, non-aureus staphylococci (NAS) are the most prevalent cause of IMI (Dufour et al., 2012). Although good progress has been made in understanding genetics of pathogen-specific clinical mastitis (Setrensen et al., 2009), studies involving genetic analysis of pathogen-specific IMI are still scarce. Therefore, the objective of this study was to estimate heritabilities for overall and pathogen-specific IMI in non-clinical, multiparous cows.
