There is little doubt but the present levels of production in Dairy Cattle have been chiefly the result of favorable feeding and environment rather than the result of breeding progress. In some ways this has been unfortunate in that feeding and certain types of environment have masked the genetic side of breeding dairy cattle. With the information concerning inheritance we now have tools with which to make a lasting improvement in our dairy cattle and other classes of livestock and plants.

The data for this study were secured during the school year 1936-1937, from the records of the University of Nebraska, Experiment Station herds, and from other herds where the bulls studied had been in service.
