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...

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...

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...

Effectiveness of selection for gains in body weight in beef cattle

Creator:: Hitchcock, Glen Henry
Abstract:: Research has yielded valuable information about the inheritance of body weight in many mammals. The results with one species may not be directly applicable to another species, but since the results do not contradict genetic theory, one must assume that the same general rules apply to all species. When the...
