Progeny Testing and Application Potentialities at Swiss Brown Population in the General of Directorate Agricultural Enterprises

Abstract

The success of dairy cattle programs is closely related to the determination of appropriate bereeding values of bulls and dairy cows, effectivenes of fertility and quantitative traits. Selection of bulls more than dairy cows are important. Progeny testing is the best accurate method for determination of the dairy bulls. breeding value. Because the information used in the progeny testing bulls came directly from the estimates of breeding value of their doughters and is highly accurate more than other information groups. In other word, the correlations between breeding value of bulls and phenotypic averages of their doughters are the highest. In addition the heritability and relationship between cows in the information group are important. In the present study, a Progeny Testing Model offered to improve Swiss Brown dairy cattle population that belonging to General of Directorate Agricultural Enterprises and Turkey.
