Milk proteins genes and microsatellite profiles in populations of Simmental cattle of different origin

In the course of investigations the estimation of distribution of milk protein genes alleles was made and also the animals' microsatellite profiles in populations of the cattle of different origin were studied. The effect of certain alleles of milk protein genes on dairy productivity in cows was revealed. The comparative genetic analysis of microsatellites and milk protein genes has shown that thoroughbred and improved animals of native selection, as expected, are closely-related, but in respect of productivity, the improved native animals and animals of Austrian selection are more related.
