G76-308 Principles Of Beef Cattle Selection, H.A. Fitzhugh, Jr. Jan 1976

G76-308 Principles Of Beef Cattle Selection, H.A. Fitzhugh, Jr.

University of Nebraska-Lincoln Extension: Historical Materials

Selection of superior seedstock leads to lasting genetic improvement by increasing the frequency of "desirable" genes and decreasing frequency of "undesirable" genes. The definition of "desirable" varies. Nature favors genes which improve fitness to survive and thrive in the natural environment. Man should favor genes which improve biological and economic efficiency of beef production.

The concepts, definitions, formulas and symbols that are the tools necessary for effective selection programs are discussed in this publication.
