摘要: Abstract Atasever, S. and Erdem, H. 2008. An investigation on the determination of mastitis risk levels milk production traits in Holstein cows. J. Appl. Anim. Res., 34: 13–16. This was conducted to determine cows (169) raised farms (24) enrolled Cattle Breeders Assocation (CBA) Samsun, Turkey, 70±14, 140+14 210±14 days 4 parities seasons. Somatic cell count (SCC), electrical conductivity (EC) catalase (CAT) were used as markers. High correlations found (P<0.01) among markers also yield parameters, except for EC daily (dMY). The results study shown that losses increase with advancing parity lactation stage winter spring calving
