The purebred Shorthorn cattle breeding project, established to study
the production traits and the effects of inbreeding, was continued during
the last year. Two inbred lines were established by the use of the
two herd sires, College Premier 29th 2368167 and Gregg Farm's Hoarfrost
2492499. The two breeding groups are referred to as the Wernacre
Premier and the Mercury lines, respectively, in reference to the
foundation sires. The Wernacre Premier line has entered the third
generation of inbreeding and the Mercury line is as yet in the first
generation of inbreeding.
