Davis, H. P. (1924). Better sires -- better stock: Build better by breeding (University of Nebraska Agricultural Experiment Station Circular No. 24)
Economy and logic indicate that the most satisfactory method of obtaining higher-yielding dairy cattle is to breed them. Nebraska raises the feeds - corn, oats and alfalfa - that will grow dairy cattle and can raise them as cheaply as any region. The method is simple. Use purebred dairy sires on the present cows. By the use of good purebred dairy sires great improvement can be obtained in a single generation.
