Test-day records of somatic cell count (SCC), milk yield, fat and protein content and six linearly scored type traits (fore udder attachment, udder depth, central ligament, rear udder height, front teat placement, teat length) of 22 613 first lactation cows from 117 herds were included in this study. SCC was log-transformed into somatic cell score (SCS). Milk yield was standardized as fat-protein corrected milk FCPM . A linear model was used to estimate the effect of different type traits on FCPM and SCS. The cows with deep udders, weak central ligaments and fore attachments and low rear udder height showed the highest SCS. Low SCS appeared to be associated with an intermediate distance between the front teats and longer teat. The cows with shallow udder had low FCPM.
