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...

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...

Actual and predicted response to selection on maternally influenced traits in the mouse

Creator:: Lind, Ronald Egnard
Abstract:: An experiment was conducted to determine if selection from standardized litters would be effective in separating lines of mice selected for increased and decreased litter weight at 14 days of age, and if response to selection on this maternally influenced trait could be accurately predicted. Data were collected on litter...

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 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...

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,...

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...

Certain genetic and maternal environmental influences on growth rate and body composition of lambs

Creator:: Addleman, Albert Duane
Abstract:: The present study was designed to investigate the relationship of milk production and milk quality to growth rate and certain organ-oleptic measurements of lambs of mutton breeds, Nine mature ewes in their fourth lactation of the Border Cheviot, Dorset Horn, Columbia, Suffolk, and Willamette breeds were acquired making a total...

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...
