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,...

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...

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...

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...

Association of genetically determined polymorphic blood components with prolificacies of purebred and crossbred pigs

Creator:: Kray, Roger LeRoy
Abstract:: Crossmatings were accomplished among three semi-closed lines within a population of pigs, for the purpose of investigating effects of crossbreeding on reproductive traits. Two of the lines were purebred (Berkshire and Yorkshire); the third line ("Composite") consisted of descendants from inter se matings among offspring of crosses of the Berkshire...
