Ova tranfers in sheep and rabbits : studies on material influences and irradiation damage

Creator:: Hunt, William Lynn
Abstract:: The first study utilized ova transfer in sheep and involved hormonal treatments for synchronization of estrus and superovulation in an investigation of crossbred maternal influences on inbred and linecross lambs. Synchronization of estrus in ewes was achieved effectively with either oral progestogen, 6 α-methyl-17α-hydroxy-progesterone acetate (60 mg./ewe/day), or intramuscular injections...

Effectiveness of selection for productive characteristics in developing the Montana no. I hogs

Creator:: McEwen, Wesley Charles
Abstract:: One of the most important productive characteristics of hogs is reproductive efficiency. Reproductive efficiency is best measured by litter size at weaning. Litter size at birth and weight of the pigs at birth are among the most important factors affecting litter size at weaning. It has been demonstrated that less...

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...

Estimation of general and specific combining abilities from a diallel cross of three inbred lines of Suffolk sheep

Creator:: Schilling, Prentiss E. (Prentiss Edwin), 1941-
Abstract:: The investigations were based on a complete diallel cross among three inbred lines of Suffolk sheep. Line of sire effects were assumed to be an estimate of general combining ability effects while sire x dam interaction was assumed to be an estimate of specific combining ability. The line of dam...

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...

Genetic parameters of the house fly (Musca domestica Linn.)

Creator:: Konanta, Sugsanguan
Abstract:: Eight strains of housefly, Musca domestica Linn., from two laboratories were intercrossed to form a stock population. Virgin males and females from the stock were collected, and nine sets, each consisting of twelve males mated to five females, were successively done. Pupae weight, adult weight, emergence time and egg production...

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...

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...
