Fifty Years of Progress in Breeding Beef Cattle

United States Department of Agriculture, Beef Cattle Research Branch, Beltsville, Maryland

Abstract

To summarize, the past half century has been an interesting one from the standpoint of beef cattle breeding. Progress has undoubtedly been made by the industry in developing types and kinds of cattle which meet market demands better than was the case many years ago. The evidence is less clear on whether the cattle available are, themselves, inherently more productive than those which were available for use by our grandfathers. Progress in beef cattle breeding research, during this half century and particularly during the past 20 years, has great promise of holding the key to the development of inherently more efficient cattle. It is hoped that definite progress in the industry as a whole can be reported long before this Society celebrates its one hundredth anniversary.
