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...

Effects of radiation on selection progress in mice

Creator:: Womack, James Ernest
Abstract:: The effects of x-irradiation on quantitative genetic traits was investigated by comparing the response of irradiated mice to selection for litter size and 28-day weight with the response to selection for the same two traits in non-irradiated lines. Irradiated lines were maintained at three levels of x-irradiation, 25 r, 50...

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...

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...

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...

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...
