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...

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...

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...

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...

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...

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...

The comparison of two methods of evaluating inheritance of milk production of dairy sires

Creator:: Srinives, Supote
Abstract:: The production records used were all converted to a comparable based, 305 day lactation period, two times a day milking, and mature equivalent (305 days-2-x-ME) of 71 cows from four Holstein bulls and 59 cows from four Jersey bulls were used for the study. The Equal Parent Index, Regression Index...

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...
