The main goals of the 2022 Rutgers Equine Science Center (ESC) needs assessment survey were to: 1) characterize the equine community, 2) identify information sources used by the equine community, 3) assess the usefulness of selected equine-related services and programs, and 4) determine the perceived importance of selected equine-related issues. An anonymous online survey was distributed through the Rutgers ESC's email list, a press release, and social media. Analysis-eligible surveys were received from <em>n</em> = 493. Most participants were female (92.7 %), 36-60 years of age (48.4 %), white (88.8 %), and horse owners (87.8 %). The top three sources of equine-related information used were 1) personal knowledge (95.7 %), 2) the veterinarian (93.7 %), and 3) the farrier (83.7 %). The survey showed that the provision of horse health information is the most useful service that the Rutgers ESC specifically can provide (79.3 %). This service may also be most useful for other extension programs, but a follow-up study is needed for clarification. The five equine-related issues most often considered to be extremely important were “Lameness and Soundness” (76.5 %), “Ethical Use of Horses” (73.2 %), “Nutrition” (63.9 %), “Right to Farm” (56.8 %), and “Care of Old Horses” (55.6 %). The survey provided insights into the current demographics of the equine community, highlighted personal knowledge, veterinarians and farriers as important information sources, and elucidated “Lameness and Soundness” as the most important equine-related issue.</p></div>","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":"142 ","pages":"Article 105193"},"PeriodicalIF":1.3,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0737080624001990/pdfft?md5=ee2944a13e2d7780fb32c8ec19c71b74&pid=1-s2.0-S0737080624001990-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142271205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to identify if salivary pH was altered by 1) a range of different feedstuffs and (2) specifically by feeding haylages with differing nutrient profiles. Two studies were conducted. The first measured oral pH following five feedstuffs, (hay, haylage, unmolassed sugarbeet pulp, unmolassed alfalfa chaff and rolled oats), tested individually over five days. Saliva (≥1 ml) was collected in triplicate, prior to feeding, directly after ingesting 500 g of each feedstuff, then 15 min and 30 min post-prandially. Oral pH was determined (pH meter) within 10 min of collection. In study two, eight ponies, were fed as their total diet, four different haylages over four 15-day periods. Saliva was collected, prior to feeding and immediately after ingesting 500 g of forage on day 1, day 6, and day 12 of each period. Samples were collected and analysed as per study one. All data were analysed by repeated measures ANOVA, and in study two linear regression was used to attempt to predict nutrients that influenced oral pH. All statistics were conducted in Genstat 20 th Ed. Only feeding unmolassed sugarbeet caused a reduction (p<0.001) in oral pH. There were differences in oral pH depending on the type of haylage fed in study two but at all times oral pH post-feeding was the same or greater than basal pH. These studies suggest any feed associated modulation of oral pH in horses may only be short-lived and quickly buffered by saliva.

The role of gastrointestinal factors, such as incretin hormones, in the pathogenesis of ID and hyperinsulinaemia in horses is poorly understood, particularly in comparison to other species. Glucagon-like peptide-2 (GLP-2) is an intestinotrophic peptide released from L cells in the gastrointestinal tract and is implicated in metabolic dysfunction in other species. The aim of this study <em>in vitro</em> was to establish basic physiological understanding about intestinal secretion of GLP-2 in horses. Basal and glucose-stimulated GLP-2 secretion was measured in post-mortem tissue samples from the duodenum, jejunum, and ileum. We observed that GLP-2 secretion was minimal in samples from the duodenum compared to the jejunum and ileum (5-9-fold higher; P < 0.05). Furthermore, GLP-2 secretion was not responsive to glucose stimulation in the ileum or duodenum but was responsive to glucose in the jejunum. This effect in the jejunum was inhibited by 30 % (P = 0.02) using phlorizin, a selective sodium-glucose cotransporter-1 (SGLT-1) inhibitor, and by 38 % (P = 0.04) using phloretin, a non-selective SGLT-1/GLUT-2 inhibitor. The localisation of glucose-responsive GLP-2 secretion in the jejunum might be relevant to the development of post-prandial hyperinsulinaemia. This study has provided data on GLP-2 secretion from the equine small intestine that will enable more complex and dynamic studies on the pathogenesis of ID.</p></div>","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":"142 ","pages":"Article 105179"},"PeriodicalIF":1.3,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0737080624001850/pdfft?md5=06082b63f6d81e4c63ba3aaab452c8c7&pid=1-s2.0-S0737080624001850-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142089049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Horses competing internationally in three-day eventing must pass two mandatory inspections (pre-competition and post-cross country) before attempting the final phase: the jumping test (JT). We hypothesized that digitally quantifying objective gait parameters captured during the two mandatory inspections will identify locomotor characteristics that predict success during the jumping test. Utilizing the DeepLabCut (DLC) software package for labeling of anatomical landmarks and a custom analysis pipeline we calculated gait parameters for 194 competition horses at the trot. During the pre-competition inspection, relative trot speed was significantly associated (P = 0.0060, GLMM), and the forelimb travel trended towards significance (P =0.0800, GLMM), with achieving a clear round in the later jumping test. Post-cross country, the forelimb travel significantly predicted JT results (P = 0.0188, GLMM). As our parameters are scaled for body size, these parameters may indicate conformational characteristics for superior jumping ability and overall athletic fitness. Within each competitive effort, comparisons of the post-cross country and pre-competition observations revealed that the change in speed and duty factor were significantly different in the group that accrued jumping faults (P = 0.00376 and P = 0.02430, GLMM), perhaps capturing locomotor signs of exercise fatigue. Further work employing these approaches to better understand competition performance will encourage the use of objective measures to protect sport horse welfare, as well as provide an advantageous tool for gait evaluation in the horse.</p></div>","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":"141 ","pages":"Article 105166"},"PeriodicalIF":1.3,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142004314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
