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...
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...
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...
Since 1939, scientists have studied estrous cycle manipulation in dogs resulting in more articles published in this field than any other area of canine reproduction. Estrous cycle manipulation in dogs must be safe and reliable. Dopamine agonists, gonadotropin-releasing hormone agonists, and gonadotropins are hormones that have been used for estrus...
Mammary tumors are the third most common tumor in cats after cutaneous neoplasia and lymphosarcoma. More than 80% of feline mammary tumors are adenocarcinomas, which are similar to human mammary adenocarcinomas in their biologic behavior and histologic characteristics. Despite treatment with radical mastectomy, feline mammary adenocarcinoma is associated with a...
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....
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...
Transcriptome gene expression studies of sperm RNA have been utilized in a variety of different species to investigate causes of male infertility. Previous research investigators have optimized cell separation and RNA isolation techniques for each species of interest. To date, no study has been completed for dogs. The objective of...
This research investigated the development of a novel canine model to study preeclampsia. Normal canine placental development has morphologic and histologic similarities to the shallow trophoblast invasion occurring with preeclampsia in humans, which makes the dog a particularly good choice for modeling this disease and will be an improvement on...
