    Abstract The field of equine sports medicine and rehabilitation provides a career opportunity for students interested in remaining in the horse industry but not focused on a career as a veterinarian. However, throughout the United States, there are limited educational opportunities for undergraduate students to prepare for this career. The objective of this work was to determine what skills and theoretical knowledge professionals in the equine rehabilitation industry deemed most useful for employment in the equine rehabilitation industry, and, using that information, develop a curriculum to meet these industry needs. To meet this objective, a Qualtrics survey was distributed through email and social media to veterinarians, veterinary professionals, rehabilitation service providers, and horse owners. In addition to demographics, the survey asked respondents to list practical skills and theoretical knowledge that are essential for professionals in the equine rehabilitation industry. The majority of the 117 respondents (84%) were located in the United States, with the remainder from Canada (5%), the United Kingdom (5%), and several other countries. Eighteen percent of respondents were veterinarians, 26% owned or managed rehabilitation facilities, 8.5% were veterinary technicians, and the remainder were horse owners, rehabilitation service providers, and others. Horse handling skills (19%) and communication skills (18%) were the most commonly listed practical skills deemed essential for rehabilitation professionals. Of the theoretical skills, evaluation of lameness (29.5%), anatomy (31%), and fundamentals of equine reconditioning programs (32%) were deemed equally important for rehabilitation professionals. These data were used to design a minor in Equine Sports Rehabilitation that incorporated fundamental knowledge in lameness evaluation and rehabilitation methods as well as significant hands-on opportunities with rehabilitating horses and communicating about rehabilitation methods and progress with clients.

    Abstract The continuous monitoring of stress, pain, and discomfort is key to providing a good quality of life for horses. The available tools based on observation are subjective and do not allow continuous monitoring. Given the link between emotions and sympathetic autonomic arousal, heart rate and heart rate variability are widely used for the non-invasive assessment of stress and pain in humans and horses. However, recent advances in pain and stress monitoring are increasingly using electrodermal activity (EDA), as it is a more sensitive and specific measure of sympathetic arousal than heart rate variability. In this study, for the first time, we have collected EDA signals from horses and tested the feasibility of the technique for the assessment of sympathetic arousal. Fifteen horses (six geldings, nine mares, aged 13.11 ± 5.4 years) underwent a long-lasting stimulus (Feeding test) and a short-lasting stimulus (umbrella Startle test) to elicit sympathetic arousal. The protocol was approved by the University of Connecticut. We found that EDA was sensitive to both stimuli. Our results show that EDA can capture sympathetic activation in horses and is a promising tool for non-invasive continuous monitoring of stress, pain, and discomfort in horses.

    Abstract Farriery can impact gait symmetry and lameness outcomes, but there is limited scientific data documenting these effects. We hypothesized that shoeing previously barefoot horses with plain stamp shoes on the hind hooves would increase gait symmetry, alter hock angles and increase range of motion, and improve lameness scores more than shoeing with traditional fullered shoes. At the start of the study, gait symmetry via wireless inertial motion sensors (IMS), kinematic gait analysis (hock angle and range of motion), and American Association for Equine Practitioner's (AAEP) lameness scoring were completed for 14 barefoot horses. Horses were then trimmed and hind hooves were shod (wk 0) in three-quarter fullered shoes or plain stamp style shoes. Horses were trimmed and re-shod at week 6. At the end of 12 wk, the IMS analysis, kinematic gait analysis, and lameness scoring were repeated. Differences between shod and barefoot values were calculated for each horse, and impact of shoe type was analyzed via t-test. Significance was determined at P ≤ 0.05. No differences were observed in the IMS scores, hock angles or range of motion, or AAEP lameness scores between horses shod in fullered or plain stamp shoes (P ≥ 0.08). As no variables were determined to be significantly different between the two shoe types, data from all horses were combined to analyze the differences between the barefoot and shod state. Shoeing increased the maximum angle of the right and left hocks (P ≤ 0.03) and the minimum angle of the left (P = 0.02) but not right hock (P = 0.23) relative to barefoot conditions. No differences in hock range of motion were observed in either hock. Lower AAEP lameness scores were observed in horses when shod compared with barefoot (P = 0.001). In conclusion, shoeing previously barefoot horses improved AAEP lameness scores and increased hock angles, regardless of the type of shoe.

    Abstract Previous research demonstrated that maternal nutrient restriction during mid- to late-gestation influenced net umbilical uptakes of glucose and amino acids in sheep. However, it is unclear how the timing and duration of nutrient restriction during mid- to late-gestation influences net uterine, uteroplacental, and fetal flux of glucose and amino acids. On day 50 of gestation, 41 adolescent ewe lambs carrying singletons were randomly assigned to one of six dietary treatments: 1) 100% of nutrient requirements from days 50 to 90 of gestation (CON; n = 7); 2) 60% of nutrient requirements (RES; n = 7) from days 50 to 90 of gestation; 3) 100% of nutrient requirements from days 50 to 130 of gestation (CON-CON; n = 6); 4) 100% of nutrient requirements from days 50 to 90 of gestation and 60% of nutrient requirements from days 90 to 130 of gestation (CON-RES; n = 7); 5) 60% of nutrient requirements from days 50 to 90 of gestation and 100% of nutrient requirements from days 90 to 130 of gestation (RES-CON; n = 7); or 6) 60% of nutrient requirements from days 50 to 130 of gestation (RES-RES; n = 7). On day 90 (n = 14) and day 130 (n = 27), intraoperative procedures were performed to evaluate uteroplacental blood flows, collect blood samples, and then ewes were euthanized. Net uterine, uteroplacental, and umbilical fluxes of glucose and amino acids were calculated by multiplying blood flow by the arterial-venous concentration difference. Data from days 90 and 130 were analyzed separately using ANOVA in SAS. Maternal nutrient restriction during mid-gestation increased (P = 0.04) net umbilical glucose uptake but, maternal nutrient restriction during late-gestation decreased (P = 0.02) net umbilical glucose uptake. Net umbilical essential amino acid uptake decreased (P = 0.03) with nutrient restriction during mid-gestation; however, net umbilical uptakes of Phe (P = 0.02), Thr (P = 0.05), Met (P = 0.09), and His (P = 0.08) increased or tended to increase after nutrient restriction during late-gestation. These data demonstrate that net umbilical glucose and amino acid uptakes were influenced by the timing of nutrient restriction during mid- to late-gestation. Elevated net umbilical glucose uptake after mid-gestational nutrient restriction was sustained throughout late-gestation, independent of late-gestational feeding level. Long-term adaptations in umbilical glucose uptake may have implications for prenatal and postnatal growth and development of the offspring.

    Abstract Poor maternal nutrition, both restricted-feeding and overfeeding, during gestation can negatively affect offspring growth, body composition, and metabolism. The effects are observed as early as the prenatal period and often persist through postnatal growth and adulthood. There is evidence of multigenerational effects demonstrating the long-term negative impacts on livestock production. We and others have demonstrated that poor maternal nutrition impairs muscle growth, increases adipose tissue, and negatively affects liver function. In addition to altered growth, changes in key metabolic factors, increased glucose concentrations, insulin insensitivity, and hyperleptinemia are observed during the postnatal period. Furthermore, there is recent evidence of altered metabolism in specific tissues (e.g., muscle, adipose, and liver) and stem cells. The systemic and local changes in metabolism demonstrate the importance of determining the mechanism(s) by which maternal diet programs offspring growth and metabolism in an effort to develop novel management practices to improve the efficiency of growth and health in these offspring.

    Abstract As writing across the curriculum becomes more important in higher education, the need for instruction about plagiarism is growing. Several plagiarism detection technologies are available to evaluate student writing and have been used to deter students from plagiarism. These technologies may be useful as an instructional tool to assist students to self-identify potential areas of plagiarism in their writing and make appropriate revisions before submission. The objectives of this work were to determine if use of the plagiarism detection software SafeAssign by students would decrease the similarity between their writing and other texts, and to gauge student response to the program. Use of SafeAssign on the first draft of a literature review did not decrease the percentage of matching text in the final draft. Instances of matching text included potential plagiarism as well as common phrases and literature cited. Students reported that use of the program was helpful in identifying potential areas of plagiarism, increased confidence in their writing, and increased their awareness of plagiarism during the writing process. The report generated by SafeAssign must be carefully interpreted by both the instructor and student, which provides an additional opportunity for dialogue about plagiarism. Use of plagiarism detection programs may be beneficial when used formatively by students during the writing process when supported by other mechanisms of instruction.

    Abstract Several sources of information are available to producers for guidance in managing their breeding flocks; however, it is unknown if sheep producers utilize any or all of these resources. Because maternal diet during gestation can have immediate and long-lasting negative effects on growth and health of offspring, it is important for producers to insure they are providing appropriate nutritional management to ewes during breeding and gestation. Historically, New England sheep producers have not been included in USDA surveys of sheep producers, and therefore, there is a lack of information about how New England producers manage their flocks, especially in terms of nutrition and gestation. The objective was to determine flock size, breeds, pregnancy detection methods, and feeding management practices of New England sheep producers. To meet this objective, a 12-question survey was developed and disseminated to New England sheep producers via Qualtrics using e-mail survey links, with a 33.2% response rate (
