Selection applied, response of traits and combining abilities of inbred lines of beef cattle

Creator:: Hoornbeek, Frank K. (Frank Kent), 1928-
Abstract:: The investigations reported are based on two studies; the first is concerned with the selection practiced for performance in one inbred Angus and three inbred Hereford lines of cattle, the realized responses, levels of inbreeding and associated performance, and heritabilities of the performance traits. Selection differentials for all performance traits...

Performance of three inbred lines of Herford cattle and their linecrosses

Creator:: Munji, Marcus Tebid
Abstract:: Three inbred and relatively unrelated lines of Hereford cattle (1. Lionheart, 2. Prince, and 3. David) developed at the Corvallis branch of the Oregon Agricultural Experiment Station as part of the W-1 project of the Western States were crossed annually from 1963 through 1965 inclusive.

Gonadotropins in pituitaries of inbred and linecross beef bulls and effects of irradiation of mammalian pituitary glands on their ability to induce in vitro ovulation of frog ovaries

Creator:: North, Warren Arthur
Abstract:: There were two studies involved in the thesis research. In the first study, variation in the amount of adenohypophysis gonadotropins among 22 individual beef bulls were investigated. These bulls represented four inbred lines, and six linecrosses. The bulls were raised in the Oregon State University purebred herd. The bulls were...
