Genetics of sheep transferrins as determined by disc electrophoresis

Creator:: Nix, Carroll Eugene
Abstract:: A total of 902 plasma samples from the Rambouillet, Targhee, Columbia, Lincoln, and Suffolk breeds of sheep were analyzed for transferrin type by disc electrophoresis. Six transferrin types, Tf[superscript A], Tf[superscript B], Tf[superscript C], Tf[superscript p], Tf[superscript E], and Tf[superscript P], were found in the Rambouillet, Targhee, and Columbia breeds...

Comparative values of liver nicotinamide nucleotide coenzymes, endocrine glands, and their relationships with production traits of diallel crossed beef bulls

Creator:: Anwar-Afghan, Mohammad
Abstract:: This investigation for the first time reports information on the correlation of various forms and ratios of nicotinamide nucleotide coenzymes in the liver tissue and endocrine glands weight with various production traits. Fifty-five inbred and line cross beef bulls raised under standard management conditions and slaughtered at 1000 lbs. body...

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...

Effectiveness of selection for productive characteristics in developing the Montana no. I hogs

Creator:: McEwen, Wesley Charles
Abstract:: One of the most important productive characteristics of hogs is reproductive efficiency. Reproductive efficiency is best measured by litter size at weaning. Litter size at birth and weight of the pigs at birth are among the most important factors affecting litter size at weaning. It has been demonstrated that less...

Effectiveness of index and elite selection methods

Creator:: Douglass, Larry W.
Abstract:: Mice were used to compare the index and elite selection methods for simultaneous selection of four traits. Selection was for litter size, birth weight, weaning weight and post-weaning gain. Progress was evaluated by examining total phenotypic merit. The standard deviations from the cycle mean for the four traits were summed...

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. Data on 137 inbred and...

An analysis of the response to selection for high and low rate of gain in the mouse, Mus musculus

Creator:: Burrill, Melinda Jane
Abstract:: An experiment was conducted to examine the responses to selection for high and low rate of gain in the mouse under a system whereby inbreeding was maximized. Rate of gain was measured by an index designed to include gains in both the pre- and postweaning periods with the gains in...

Ova tranfers in sheep and rabbits : studies on material influences and irradiation damage

Creator:: Hunt, William Lynn
Abstract:: The first study utilized ova transfer in sheep and involved hormonal treatments for synchronization of estrus and superovulation in an investigation of crossbred maternal influences on inbred and linecross lambs. Synchronization of estrus in ewes was achieved effectively with either oral progestogen, 6 α-methyl-17α-hydroxy-progesterone acetate (60 mg./ewe/day), or intramuscular injections...
