Highlights
Selection of dairy cattle in commercial herds is primarily based on production traits [1]
Some anatomical attributes of the dairy cow like the udder morphology contribute to the production
Because of the negative and significant values of the trait SDF in component 2, selection for these traits should result in good suspension of the udders leading to a short distance between teat end to the floor which is important for udder health
Summary
Selection of dairy cattle in commercial herds is primarily based on production traits [1]. The PCA analysis was applied to 17 udder and teat conformation traits in Sahiwal cows and general mean value of Kaiser-Meyer-Olkin (KMO) MSA was obtained as 0.669, indicated the existence of significant correlations between linear type traits and the existence of true factors, reinforcing the suitability of the data for PCA analysis. Most component values were positive except for SDF, the distance between teats, UB and fore udder attachment which were negative but not significant (less than 0.60) in the first PC.
