First Ladies have performed a variety of public and private roles, from presidential escort, hostess, and social advocate to policy maker and presidential advisor. The nature of the position has always been both traditional and gendered, greatly influencing each First Lady's performance. Due to the changing role of women in...
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...
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...
Background: Even with numerous successful Trap-Neuter-Release programs, feral cat populations continue to grow. Our laboratory is interested in determining if an underlying biological cause exists for the exuberant reproductive success in this once domestic subspecies. An earlier age for developing reproductive capacity (onset of spermatogenesis in males) may be one...
Gonadectomy has been associated with a 1.5-2 fold increase in the occurrence of canine hip dysplasia and a 2-3 fold increase in the occurrence of canine anterior cruciate ligament (ACL) injury. In intact dogs, luteinizing hormone (LH) is secreted from the adenohypophysis to stimulate the synthesis of gonadal hormones, which...
Postpartum uterine inflammation (endometritis) is not uncommon in beef cattle, resulting in infertility and culling. Prolonged calving may contribute to the increased incidence of endometritis in heifers. Commonly used methods to treat endometritis in beef cattle include intrauterine antibiotics and/or hormone injections, which can result in meat residues. Platelet rich...
Reproductive function in the dog is controlled by feedback mechanisms that involve the hypothalamus, the anterior pituitary gland, and the gonads. Surgical gonad removal, a common procedure performed in dogs for the purposes of sterilization, disrupts the hypothalamic-pituitary-gonadal (HPG) axis and results in permanently elevated concentrations of gonadotropins. Manipulation of...
Many domesticated animals, especially dogs, are selectively bred within a small population to select for and “fix” certain traits. This leads to decreasing genetic diversity and the potential for inherited health issues over time. The Saluki is a relatively rare breed of dog in the U.S. The Society for the...
Camelid health and parasitology experts disagree on what a “safe” level of internal parasitism is in camelids. The objective was to determine the levels of parasitism in show camelids (llamas and alpacas). The hypothesis was that fecal egg counts (FEC) in camelid would differ based upon geographic location, species (llama...
This research investigated gene expression in the canine placenta during the peripartum period. Previous studies have recognized molecular changes that occur in the placenta around the time of placental release in other species, but no study has looked at gene expression in the late gestation canine placenta. Of particular significance...
