The Use of Sex-Sorted Stallion Semen in Embryo Transfer Programs     

Juan C. Samper  Lee Morris  Tracy A. Plough 《Journal of Equine Veterinary Science》2012

Sorting stallion semen into two separate populations of enriched X- or Y-bearing sperm can be done successfully. For this, stallion semen can be shipped to a sorting facility, but the mare must be in close to the sorting laboratory. Fertility rates when using 20-40 million sperm are an acceptable 60% per insemination. The procedure can be implemented in embryo transfer programs, with no deleterious effect on the pregnancy rate or embryonic death.  相似文献   

Commercial Breeding with Sexed Stallion Semen: Reality or Fiction?     

Juan C. Samper  Lee Morris  Fernando J. Peña  Tracy A. Plough 《Journal of Equine Veterinary Science》2012

Sorting stallion spermatozoa for the purpose of separating X- and Y-bearing spermatozoal populations has had significant advances in the past 10 years. However, current technology requires that the mare be close to the laboratory processing the semen. The development of procedures to cool and freeze sex-sorted sperm will be critical if this technology is to be embraced by the equine industry worldwide.  相似文献

What is your diagnosis? Biopsy impression smear of a hepatic mass in a yearling Thoroughbred filly     

Gold JR  Warren AL  French TW  Stokol T 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》2008,37(3):339-343

A 1-year-old Thoroughbred filly was presented to the Cornell University Hospital for Animals with a 10-day history of fever, diarrhea, inappetance, and hypodipsia. Clinical pathology abnormalities found by the referring veterinarian included erythrocytosis, hyperproteinemia, and increased serum gamma-glutamyltransferase and lactate dehydrogenase activities. At Cornell University, the laboratory abnormalities were confirmed and also included thrombocytosis and hypoglycemia. Erythrocytosis persisted despite vigorous fluid therapy. Ultrasound examination revealed an extremely enlarged liver with abnormal echogenicity and a 21 x 25-cm hepatic mass with varied echogenicity. Imprints of an ultrasound-guided biopsy of the mass revealed a neoplastic epithelial population of uncertain origin, although the cells did not resemble hepatocytes. Together with the presenting signs, signalment, ultrasonographic findings, and persistent erythrocytosis, the cytologic findings were considered to be most consistent with hepatoblastoma. Histopathologic examination of the mass at necropsy confirmed the diagnosis and findings also included bone marrow erythroid hyperplasia. Serum erythropoietin concentration was 28.0 mU/mL (reference interval 1.0-11.8 mU/mL), supporting erythropoietin production by the tumor and secondary inappropriate erythrocytosis. To our knowledge, this report is the first to document secondary erythrocytosis with increased erythropoietin concentration in a horse with hepatoblastoma, and also the first to describe the cytopathologic features of this rare tumor.  相似文献   

Effect of chronic administration of a gonadotropin‐releasing agonist on luteal function and pregnancy rates in dairy cattle     

Alan Willmore  Tracy L. Davis 《Animal Science Journal》2019,90(11):1432-1443

Increased embryonic losses may be associated with inadequate progesterone (P4) concentrations in high‐producing lactating dairy cattle. The objectives of the present studies were to determine if chronic administration of a gonadotropin‐releasing hormone (GnRH) agonist, Deslorelin, would increase circulating P4 concentrations and subsequently increase pregnancy rates in dairy cattle. Administration of Deslorelin for 12 days increased (p < .05) luteal volume and circulating P4 concentrations in primiparous lactating dairy cows, but increased only luteal volumes in multiparous cows. Treatment with Deslorelin increased Day 45 pregnancy rates in cows as compared to untreated controls. Chronic treatment with Deslorelin in dairy cattle; (a) increased luteal volume of the primary CL, (b) induced accessory CL, (c) increased circulating P4 concentration in primiparous cows only, (d) did not lengthen the estrous cycle upon removal of treatment, and (e) increased pregnancy rates. Although luteal volume was increased in multiparous cows and circulating P4 concentrations were not with Deslorelin treatment, there was an apparent effect on pregnancy rates. This hormonal strategy may represent a suitable model to address local effects of P4 and GnRH/luteinizing hormone on uterine environment and subsequent embryonic survival.  相似文献   

Radiotherapy isocenters verified by matching to bony landmarks of the canine and feline head differ when localized using volumetric versus planar imaging     

Leanne M. Magestro  Joyce Y. Cahoon  Tracy L. Gieger  Michael W. Nolan 《Veterinary and comparative oncology》2019,17(4):562-569

The “gold standard” for verification of patient positioning before linear accelerator‐based stereotactic radiation therapy is kilovoltage cone‐beam computed tomography (kV‐CBCT), which is not uniformly available or utilized; planar imaging is sometimes used instead. The primary aim of this study was to determine if the position of the bony skull, when used as a surrogate for isocenter verification, is different when orthogonal megavoltage (MV) portal or kilovoltage (kV/kV) radiographs are used for image guidance, rather than kV‐CBCT. A secondary aim was to determine the influence of intra‐observer variability, body size and skull conformation on positioning, as determined using these three imaging modalities. Dogs and cats receiving radiotherapy of the head were recruited for this prospective analytical study. Planar (MV portal and kV/kV images) and volumetric (kV‐CBCT) images were acquired before treatment, and manually coregistered with reference images. Differences in skull position when matched based on MV portal, kV/kV images and kV‐CBCT were compared. A total of 65 subjects and 148 unique datasets were evaluated. The Wilcoxon rank‐sum test was used to evaluate effects of transitioning between imaging modalities. When comparing magnitude of shifts in MV to kV‐CBCT, MV to kV/kV and kV/kV to kV‐CBCT, there were statistically significant differences. Results were not measurably impacted by body size, skull conformation or interobserver differences. Based on shift magnitude and direction, an isotropic setup margin of at least 1 mm should be incorporated within the planning target volume when MV or kV planar imaging is used for position verification.  相似文献
