Gregory, Keith E. (1961) Improvement of beef cattle through breeding methods. Summary of results from Regional Project NC-1 (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 196)
The major purpose of this project is to obtain information that beef cattle breeders can use to make maximum genetic improvement in all traits of economic value in beef cattle. The major objectives of NC-1 are the following: (1) to determine the traits of economic importance in beef cattle: (2) to assess their relative value; (3) to develop reliable methods and procedures for measuring and evaluating them; (4) to obtain estimates of their heritabilities; (5) to obtain estimates of the genetic and phenotypic correlations among all economically important traits; (6) to evaluate the effects and uses of inbreeding and heterosis; and (7) to measure the importance of genetic-environmental interactions.
