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.

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-

Genetic and physiological relationships of growth hormone and growth in goats

Creator:: Simms, Danny Dale
Abstract:: An F₁ population resulting from mating pygmy and normal goats (local commercial breeds) was crossed to give an F₂ population. Analysis of wither height and body weight indicated that the F₂ population was intermediate between the parental types (pygmy and normal) with little overlap of phenotypic values for body size...

Response of scorbutic guinea pigs to ascorbic acid and adrenocorticotropic hormone (ACTH)

Creator:: Riker, Joseph Thaddeus III
Abstract:: Thirty-six female guinea pigs were placed on a scorbutogenic diet for 14 days and then divided into groups of four. Three groups received adrenocorticotropic hormone (ACTH) with each group given 10, 20, or 40 units. Three groups each received 50 mg of ascorbic acid and three groups received 50 mg...

Effect of certain blood enzymes and cellular constituents on growth in different genetic groups of sheep

Creator:: Hutto, Daniel C.
Abstract:: In the present study, five breeds of ewes and their lambs were utilized. The breeds used were: Border Cheviot, Dorset Horn, Columbia, Suffolk and Willamette. In all, 31 ewes and 42 lambs were involved. The blood constituents which were determined for the ewes and lambs were: acid and alkaline phosphatase,...

Relationship of certain blood nitrogen constituents with growth in different genetic groups of sheep

Creator:: Yodseranee, Somchit
Abstract:: Market lamb production usually requires a short period of time. The success of production is therefore dependent upon the growth rate of the lambs which is influenced by milk yields of the ewes. Different growth potentials of animals result from a difference in their utilisation of food. Since metabolism affects...

Genetics of sheep transferrins as determined by disc electrophoresis

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...

Genetic and physiological factors associated with gonadotropic and thyrotropic hormone content of sheep pituitaries

Creator:: Plotka, Edward Dennis
Abstract:: Data were taken from 47 animals consisting of five breeds: Border Cheviot, Columbia, Dorset Horn, Suffolk, and Willamette. Both sexes were represented in each breed, although in unequal numbers. The pituitaries were assayed for gonadotropic and thyrotropic hormone content by injecting a suspension of the macerated gland in saline into...

Hormonal stimulation of breeding activity in different genetic groups of ewe lambs

Creator:: West, Dennis Errol, 1942-
Abstract:: An investigation of the effects of exogenous gonadotropic treatments on fertility of various genetic groups of ewe lambs were run over a six-year period. Since hormonal treatments varied and the experimental animals were different from one breeding season to the next, each year comprised a separate study. Hormone treatment included...
