  • 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...

  • 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,...

  • Response of scorbutic guinea pigs to ascorbic acid and adrenocorticotropic hormone (ACTH)

    Creator:
    Riker, Joseph Thaddeus III
    Abstract:
    Thirty-six female guinea pigs were placed on a scorbutogenic diet for 14 days and then divided into groups of four. Three groups received adrenocorticotropic hormone (ACTH) with each group given 10, 20, or 40 units. Three groups each received 50 mg of ascorbic acid and three groups received 50 mg...

  • Relationship of certain blood nitrogen constituents with growth in different genetic groups of sheep

    Creator:
    Yodseranee, Somchit
    Abstract:
    Market lamb production usually requires a short period of time. The success of production is therefore dependent upon the growth rate of the lambs which is influenced by milk yields of the ewes. Different growth potentials of animals result from a difference in their utilisation of food. Since metabolism affects...

  • 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 and physiological factors associated with gonadotropic and thyrotropic hormone content of sheep pituitaries

    Creator:
    Plotka, Edward Dennis
    Abstract:
    Data were taken from 47 animals consisting of five breeds: Border Cheviot, Columbia, Dorset Horn, Suffolk, and Willamette. Both sexes were represented in each breed, although in unequal numbers. The pituitaries were assayed for gonadotropic and thyrotropic hormone content by injecting a suspension of the macerated gland in saline into...

  • 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...

    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...
