Honeybees are essential for agriculture and to sustain an ecosystem. There are two main types of bacterial diseases that affect honeybee colonies and brood: American Foulbrood and European Foulbrood. Both bacterial diseases can be treated with antibiotics approved for use in honeybees, however American Foulbrood is spore forming and cannot...
Sperm acrosome associated 3 protein (SPACA3) is a unique, intra-acrosomal, conventional-type lysozyme-like protein of mammalian spermatozoa. SPACA3 is present in all stages of ovarian follicles and is localized to granulosa cells and ooplasma in humans, mice, cows, dogs, and cats. The objective of this study was to determine if equine...
There are over two million pet rabbits in the United States. Many rabbits are obtained as adults from pet stores and humane societies. Pet rabbit owners may elect to perform ovariohysterectomy (spay) surgeries on female rabbits to prevent unwanted pregnancies as well as to eliminate the possibility of reproductive disorders...
The canine estrous cycle is unique compared to other domestic animal species. During estrus, serum progesterone concentrations ([P4]) rise two days prior to ovulation. In fact, the luteinization of pre-ovulatory follicles resulting in this initial increase in [P4] (1.5-2.5 ng/ml) cannot be temporally dissociated from the onset of the surge...
Luteinizing hormone (LH) is secreted in low-amplitude pulses in sexually intact dogs to stimulate synthesis of estrogen and testosterone in females and males, respectively. LH is mainly considered a reproductive hormone, but LH receptors (LHR) have been identified in non-reproductive tissues, including in canine lymphoma and isolated canine T-cell lymphoma...
The objective of this research was to determine if acupuncture can reduce bovine mammary inflammation. Lactating cows at the Oregon State University Dairy Research Center were selected based on Dairy Herd Improvement Association reports indicating a SCC >500,000 cells/mL. A California Mastitis Test (CMT) score of greater than one was...
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...
The current American free-roaming horse (Equus caballus) population far exceeds the appropriate population limit set by the Bureau of Land Management (BLM) to preserve resources on public lands. Several techniques have been tested to assist in decreasing repopulation rates. The purpose of the present study was to analyze two contraceptive...
Post-mortem examinations were performed on 29 deceased Persian kittens from 13 different litters, and 30 deceased Devon Rex kittens from 18 different litters in order to identify gross anatomical abnormalities. Fifteen kittens were stillborn (8 Devon Rex, 7 Persian), 17 kittens died during the first day of life (16 Devon...
