In cattle the analysis of the genetic polymorphism of milk proteins provides an effective tool both to characterize the genetic diversity and to improve the efficiency of selection for specific production traits. Four genes, αS1-casein (CSN1S1), β-casein (CSN2), κ-casein (CSN3) and β-lactoglobulin (BLG) have showed a high level of genetic polymorphism and are candidate to play a role in selection programmes in order to improve milk production. In this work three Bos genus populations, one taurine breed autochthonous of South-East of Sicily (Modicana) and two Bos indicus populations (Azaouak and Gudali) reared in Niger and Cameroon, respectively,..........
