Selection applied, response of traits and combining abilities of inbred lines of beef cattle

Creator:: Hoornbeek, Frank K. (Frank Kent), 1928-
Abstract:: The investigations reported are based on two studies; the first is concerned with the selection practiced for performance in one inbred Angus and three inbred Hereford lines of cattle, the realized responses, levels of inbreeding and associated performance, and heritabilities of the performance traits. Selection differentials for all performance traits...

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...

Electrocardiograms and related variables of dwarf beef cattle

Creator:: Pinjani, Moti, 1939-
Abstract:: Electrocardiograms from 12 compressed male (CM), 16 compressed female (CF), ten synthetic compressed female (SCF), nine brachycephalic female (BF), and 15 dolichocephalic female (DF) dwarfs from Davis, California, taken in the scapular lead S-II (prescapular position positive and right forelimb negative) were analyzed, The data on dwarf electrocardiograms were compared...

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,...

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...

Estimates of combining abilities, heterotic effects and phenotypic correlations among in-bred lines of beef cattle and their line-crosses

Creator:: Humes, Paul Edwin
Abstract:: The investigations were based on a complete diallel cross among three inbred lines of Hereford cattle. Records of Angus calves born during the same period were used to obtain more accurate estimates of environmental effects and to determine breed differences among the various traits included in the study. Estimates of...

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...

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...
