Abstract excerpt

Automated milking systems (AMS) enable the generation of objective measurements of teat placement, a key factor influencing milking efficiency and udder health. In this context, we performed GWAS to investigate the genetic background of 2 teat placement traits, i.e., rear teat distance (RTD) and front teat distance (FTD), derived from Cartesian coordinates recorded by AMS in American Holstein cows. Phenotypic...
