In 1913 the Nebraska Legislature appropriated $17,500 to establish a Dairy Department at the North Platte Experiment Station. The department's herd was to be used in demonstrating management and breeding practices and as a source of breeding stock.

Since the North Platte herd was started, research in the field of animal breeding has developed new concepts in many phases of dairy cattle breeding and selection. In 1948 a regional project was started to study the improvement of dairy cattle through breeding and the herd of Holstein cattle at the North Platte Experiment Station became a part of this project.

The purpose of the present study is to analyze the progress made under a system of dairy cattle breeding and selection carried out according to the principles that dominated 40 years ago. The results of this study should form a basis upon which the application of more recent findings in the field of dairy cattle breeding can be evaluated.
