  • Advances in Camelid Theriogenology

    Creator:
    McAllister, Anna
    Abstract:
    Reproductive physiology of South American camelids is unique, especially in comparison to other domestic animals. For example, mating occurs in a recumbent position over a period of approximately 30 minutes. Males are dribble ejaculators, and the camelid ejaculate is highly viscous making it nearly impossible to work with in vitro....

  • Comparing the Ovarian Expression of Sperm Acrosome Associated 3 Protein in Young and Adult Queens

    Creator:
    Ramsey, Ann M.
    Abstract:
    The purpose of this thesis was to quantify sperm acrosome associated 3 (SPACA3) protein expression in the ovaries of young (3.0±0.9 months, n=11) and adult (10.4±2.8 months, n=11) queens. It was hypothesized that SPACA3 expression would not differ between age groups. Immunohistochemistry was performed on formalin-fixed, paraffin-embedded feline ovarian sections...

  • Reproductive Effects of PG-600 Administration in Ewes

    Creator:
    Habeeb, Hayder
    Abstract:
    Sheep are seasonally polyestrus, which means they do exhibit estrus and ovulation during the short daylight (breeding season) and do not during the long daylight (nonbreeding season). To stimulate the ewes to ovulate during the nonbreeding season, various hormonal treatments have been used. PG-600 contains both equine chorionic gonadotropin and...

  • Prevalence of Canine Brucellosis in the United States

    Creator:
    Douglas, Lisa
    Abstract:
    Brucella canis is a zoonotic proteobacterium causing brucellosis in dogs and other wild canidae. It is primarily spread to the fetus through the placenta, to other dogs through fetal fluids and vaginal discharge after abortion, and to mating partners through vaginal and seminal fluids. Transmission to other dogs can also...

  • A Report on the Goat Industries of Oregon

    Creator:
    Lamphere, Charlotte A.
    Abstract:
    Goats were the first livestock species to be domesticated by humans and continue to function as a key source of protein and economic value for many communities. In the sixteenth century, Spanish colonists brought goats to the Americas. Unlike other nations, the United States did not maintain a significant market...

  • Acupuncture prevents the postpartum reduction in matrix metalloproteinase type-2 concentration and enzyme activity in bovine caruncles

    Creator:
    Hiebel, Katrina A.
    Abstract:
    The objectives of this study were to determine the effects of acupuncture in dairy cows on caruncular matrix metalloproteinase type-2 (MMP2) tissue concentration and enzyme activity at 0, 2, and 4 hours after calving. Immediately after natural calving, a caruncle was obtained from the body of the uterus and flash...

  • Canine LH Receptors Expression in Non-neoplastic and Neoplastic Tissues

    Creator:
    Zwida, Khawla
    Abstract:
    Throughout most of the developed world, surgical sterilization via gonadectomy has become a common tool for combating the overpopulation of unwanted dogs as well as to eliminate the risk of reproductive diseases in pet dogs. In the dog as in other normal adult mammal, the hypothalamus secretes gonadotropin-releasing hormone (GnRH),...

  • Determining the Onset of Reproductive Capacity in Free-Roaming, Unowned Cats

    Creator:
    Bohrer, Ellie
    Abstract:
    The purpose of this thesis was to determine if an underlying biological cause exists for the exuberant reproductive success in free-roaming unowned (FRU) cats. The hypothesis for this thesis was that FRU tom and queen cats have reproductively adapted to man-made sterilization efforts by lowering the age at which they...

  • Matrix metalloproteinase type-2 and type-9 immunoexpression in bovine caruncular tissue at the time of calving, 2 hours post-calving, and 4 hours post-calving

    Creator:
    Gentle, Lauren and Kutzler, Michelle
    Abstract:
    As bovine parturition nears, the placentome undergoes changes that allow placental delivery within 12 hours after calving. These changes include the expression of enzymatic proteins (e.g. MMPs) within the placentome that are capable of breaking down collagen, allowing for the separation of the cotyledon from the caruncle. Dysregulation of either...

  • Evaluation of novel swim-up approaches on canine sperm progressive motility, concentration, morphology, and acrosome reaction

    Creator:
    Lengele, Amber
    Abstract:
    Introduction: Swim-up has been considered a preferred method for separating non-motile sperm in an ejaculate. However, the long incubation time and equipment necessary for swim-up make this process clinically impractical. It was hypothesized that these problems could be avoided for canine applications with a shorter incubation time at room temperature...
