One assisted reproductive tool used to propagate highly desirable genetics from elite sire and dam matings is embryo transfer. Superovulation is the first part of the overall protocol and it is a required yet costly and biologically stressful procedure in cattle embryo transfer. The process of superovulation results in high...
Plethodontid salamanders have served as an informative vertebrate system for studying the role of chemical signals in facilitating social and reproductive behaviors. Individuals produce complex mixtures of chemicals from multiple glandular regions. In total, these secretions convey a wide variety of information, and are important for numerous inter- and intraspecific...
Feline injection site sarcomas (FISS) are frequently encountered cutaneous and subcutaneous neoplasms of cats. Significant patient morbidity is related to the invasiveness these tumors display, typically requiring extensive local excision or amputation. As with many veterinary tumors, survival time and tumor recurrence for FISS is highly influenced by histologic margin...
The purpose of this study was to determine the degree to which public universities
are providing subsidies to tax-exempt, non-profit, legally distinct corporations
which serve as university-affiliated foundations. Specifically, this investigation
sought to determine (a) the percentage of universities providing subsidies, (b) the
types of subsidies provided, (c) the dollar...
The kinematic characteristics of 17 elite male cross-country skiers competing in the 50 km race of the 1992 Winter Olympic Games were determined. Each skier used the open field skating technique, one of four skating techniques used in free technique cross-country ski races. Skiers were filmed by the use of...
Many organisms with complex life cycles undergo transition periods associated with increased vulnerability to predation. Several evolutionary adaptations have been proposed as antipredator defenses for organisms during risky transition periods. These include: shortening of the transition period, parental care, cryptic coloration, and synchrony of risky transitions with large numbers of...
Sex steroids, follicle stimulating hormone (FSH),
luteinizing hormone (LH) and gonadotropin releasing hormone
(GnRH) were measured in monosex and mixed sex populations of
rainbow trout during early development. Steroids declined
following fertilization, increased at hatch, then fell and
remained constant thereafter. Trends toward differences in
steroids between males and females...
The Bureau of Land Management (BLM) maintains a growing number of feral horses on public rangelands. With population growth rates as high as 22% annually, herds are exceeding their carrying capacity and millions of dollars are spent maintaining captured horses in holding facilities awaiting adoption. To manage the feral horse...
Incidences of uterine infections in dairy cattle are high between parturition and Day 21 postpartum. Dairy cows with uterine infections are at risk for prolonged periods of days open and multiple services before becoming pregnant. Neutrophils are the first wave of immune system defense against uterine contamination. Neutrophil function seems...
