Some genetic and environmental factors affecting weaning weights of lambs

Creator:: Dahmen, J. J. (Jerome John), 1919-
Abstract:: Eight purebred rams (four Suffolk and four Panama) previously selected as high and low on the basis of post-weaning performance feed test of 84 days were used each of three years. Each of the rams was mated to approximately 25 grade Panama ewes each year. One ram and 25 ewes...

Genetic polymorphism of sheep hemoglobin

Creator:: Templeton, Joe Wayne, 1941-
Abstract:: Five breeds of sheep (Columbia, Targhee, Rambouillet, Lincoln, and Suffolk) were found to possess two hemoglobin types (Hb. A and Hb. B) when their hemoglobins were examined by disc gel electrophoresis. The hemoglobin alleles proved to be co-dominant. Three of the breeds (Columbia, Targhee, and Rambouillet) were maintained at altitudes...

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...

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...
