Wilson","doi":"10.58292/ct.v15.9270","DOIUrl":"https://doi.org/10.58292/ct.v15.9270","url":null,"abstract":"Oxytocin is used increasingly in mares to prolong corpus luteum (CL) function to suppress estrus. When mares develop prolonged CL function in response to oxytocin treatment, the CL generally remains functional for 60–90 days. However, a longer duration of CL function can make this method of estrus suppression even more clinically useful. We hypothesized that human chorionic gonadotropin (hCG) treatment during the period of oxytocin-induced prolonged CL function would extend the duration of CL function (i.e. beyond 90 days). Prolonged CL function was induced in mares (n = 14) by treating them with 60 units of intramuscular oxytocin once daily on days 7–14 after ovulation. Mares were then randomly assigned equally to a control group that received no additional treatment and an hCG-treated group that received 2,500 units of intramuscular hCG on days 30, 45, 60, 75, and 90 after ovulation. Jugular blood samples were collected for progesterone concentration determination on the day of ovulation and then 3 times (M, W, and F) weekly for 120 days. Duration of CL function was not different (p > 0.05) and it was 78.0 ± 7.5 and 91.4 ± 20.4 days (mean ± standard deviation [SD]) in control and hCG-treated mares, respectively. Therefore, hCG treatment (during the period of oxytocin-induced prolonged CL function) did not extend CL function, hence alternative methods should be explored.","PeriodicalId":93421,"journal":{"name":"Clinical theriogenology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45549276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Documented methods of pregnancy diagnosis include radiography, progesterone assays, transrectal palpation, and transrectal and transabdominal ultrasonography; however, there is variability in fetal count accuracy with each of these methods. Abdominal radiography evaluation in 13 pregnant ewes among observers of various skill levels was compared retrospectively with the known number of fetuses determined using computed tomography. Overall accuracy using abdominal radiography across skill levels for determining fetal counts correctly was 79%. Accuracy decreased as the number of fetuses increased, with accuracies for singleton, twin, and triplet pregnancies being 92, 72, and 50%, respectively. Additionally, observer experience was inversely related to radiographic fetal count accuracy.","PeriodicalId":93421,"journal":{"name":"Clinical theriogenology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48885549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many factors can cause disturbance in libido (e.g., lameness or physical pain, hormonal, age, experience, and handling). Identifying the cause of poor libido is important to determine the best treatment approach. A 6-year Thoroughbred stallion was presented for failure of intromission when attempting to breed mares. Stallion was recently retired from racing. Stallion was placed on hormonal therapy that did not change stallion’s aberrant reproductive behavior. On presentation no obvious physical causes were identified and the stallion displayed masturbation behavior. Through the review of video recordings of the breeding sessions, modifications were made that eventually resulted in the stallion successfully breeding mares without hormonal intervention. This case illustrated how video recordings of breeding activity can help in determining cause of reproductive dysfunction. Furthermore, interpretation of peripheral steroid hormone concentrations needs to be carried out with caution.","PeriodicalId":93421,"journal":{"name":"Clinical theriogenology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70899998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among carnitines, only L-carnitine’s effect on stallion semen has been tested and not acetyl-L-Carnitine. Therefore, we aimed to determine the ideal concentrations of L-carnitine (LC) and acetyl-L-carnitine (AC) and their effects on stallion semen cooled at 5℃ for up to 48 hours. Semen was extended to 50 x 106 sperm/ml in commercial extender (Control), and concentrations of 5, 10, and 15 mmol/l of LC and AC were evaluated in Experiment 1. Sperm motility and plasma membrane integrity were assessed by CASA and epifluorescence microscopy, respectively. In Experiment 2, the combination of the intermediate doses of LC (10 mmol/l) and AC (10 mmol/l) was tested. Sperm parameters were evaluated as in Experiment 1 and in addition, DNA fragmentation index (DFI), production of reactive oxygen species (ROS), and lipid peroxidation (PEROX) were evaluated by flow cytometry. All analyses were performed at 0, 24, and 48 hours after semen collection, processing, and cooled-stored at 5°C. In Experiments 1 and 2, the groups supplemented with LC and AC or LC+AC had higher plasma membrane integrity and motility parameters compared to Control group (p < 0.05). The LC and AC combination did not change sperm parameters compared to LC or AC alone (p > 0.05). No differences (p > 0.05) were observed for DFI, ROS, and PEROX.
