Serum T₄ and liver NAD and NADP as performance indicators in beef cattle

Creator:: Brokaw, Bryan Edward
Abstract:: The relationships of serum T₄ (thyroxine) levels and liver nicotinamide nucleotide coenzyme (NAD and NADP) levels with production of traits of beef cattle were investigated at both weaning (182 kg) and following performance testing (363 kg). In addition, the value of these parameters as selection criteria for improved performance was...

Morphology of epididymal spermatozoa from inbred and linecross bulls

Creator:: Turner, H. A.
Abstract:: Data were presented on epididymal spermatozoa from 29 inbred and linecross bulls raised at Oregon State University in connection with the Western Regional Beef Cattle Breeding Project, W-1. The inbred bulls came from four inbred lines. Three of these inbred lines were Herfords and the other line was Angus. The...

Actual and predicted response to selection on maternally influenced traits in the mouse

Creator:: Lind, Ronald Egnard
Abstract:: An experiment was conducted to determine if selection from standardized litters would be effective in separating lines of mice selected for increased and decreased litter weight at 14 days of age, and if response to selection on this maternally influenced trait could be accurately predicted. Data were collected on litter...

A clinical and genetic study of tuberous sclerosis

Creator:: Edwards, Thomas Allen
Abstract:: Tuberous sclerosis is a serious heritable human disorder that involves many organ systems. It was first recognized as a disease entity over a century ago. Its mode of transmission in familial cases has been fairly well established to be that of a single gene locus autosomal dominant trait. However, the...

Estimation of general and specific combining abilities from a diallel cross of three inbred lines of Suffolk sheep

Creator:: Schilling, Prentiss E. (Prentiss Edwin), 1941-
Abstract:: The investigations were based on a complete diallel cross among three inbred lines of Suffolk sheep. Line of sire effects were assumed to be an estimate of general combining ability effects while sire x dam interaction was assumed to be an estimate of specific combining ability. The line of dam...

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...
