Blood and Milk Protein Polymorphism and Their Effects on Various Production Traits in Simmental Cows

Abstract

This research was carried out to determine the transferrin (Tf) and haemoglobine (Hb) and milk protein (alfa-S-1-casein, beta casein, capa casein, beta lactoglobuline) types, and relationships between Tf and Hb types and milk protein genotypes with various characteristics. The relationship between Tf types and milk yields of control milking and control day were only statistically significant (P<0.05). The relationship between Hb types and control milking milk yield were also found statistically significant (P>0.05). None of the investigated characteristics were effected by milk protein genetic variants at statistically significant level.
