The relationship between the gut microbiome and brain function has been described in behavioral disorders such as schizophrenia, depression and anxiety in humans.

This study aimed to characterize the fecal microbiome and the predicted functional profile of horses with and without aerophagia. Fecal samples were collected from 12 Colombian Creole Horses of both sexes, divided into two groups: group 1, composed of six horses with crib-biting (3 females and 3 males), average body weight of 330 ± 10 kg, age of 7.0 ± 1.2 years and body condition score (BCS) of 5/9 ± 1 and group 2, consisting of six horses without crib-biting (3 females and 3 males), average body weight of 335 ± 5 kg, age 6.5 ± 1 years and BCS of 6/9 ± 1. From each horse in both groups fecal total DNA was obtained and 16S ribosomal RNA gene amplicons were sequenced to characterize the bacterial community structure. Community structure and differential abundance analyses revealed significant differences between the two conditions (p < 0.05). Specifically, the fecal microbiota at the family level in crib-biting horses, showing a decrease in <em>Bacteroidales</em> and an increase in <em>Bacillota</em> and <em>Clostridia</em>, differed from that of healthy horses without crib-biting, consistent with findings from previous studies. Furthermore, metagenome prediction suggests metabolic profile changes in bacterial communities between both conditions in horses.

The study involved 25 recipient mares that demonstrated embryonic vesicles inside intraluminal fluid (ILF) on ultrasound scanning 2 ± 0.5 days after ET. Seven recipient mares were left without re-flushing and re-transferring of embryos (control group) and 18 recipient mares (treated group) were subjected to re-flushing and re-transferring of the embryos to second healthy and prepared recipients. The retrieved fluid from treated mares was subjected to microbiological and cytological examinations. The results revealed mixed and single infections, as well as polymorphonuclear neutrophils (PMNs). The total bacterial count and cytology findings revealed that all first recipient mares had endometritis. All control mares showed embryonic death at 14 ± 1.1 days (13–15 days) of embryonic age. In treated group, microscopic evaluation of retrieved embryos revealed a well-developed thick capsule in 12/18 (66.7 %) of them and a normal capsule in 6/18 (33.3 %). The pregnancy rate in well-developed capsule embryos was greater (66.7 %) than in typical capsule embryos (33.3 %). This study illustrates the value of swabbing the uterus of the recipient mares during estrus prior to ET and their checking at 2 days after ET. In addition to boosting pregnancy rates in ET commercial programs, our novel method can protect the embryos from the harmful effects of the inflammatory process and help them survive.</div></div>","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142288999","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}

Our objectives were to determine the effects of different shoeing conditions on equine neck and back kinematics at walk and trot in straight line over sand. Two-dimensional kinematic video analysis was performed under seven shoeing conditions: front feet shod with aluminum shoes and hind feet with steel racehorse shoes (REFSHOD), front aluminum shoe and hind feet unshod (FORESHOD), front feet unshod and hind steel race shoes (HINDSHOD), all four feet unshod (UNSHOD), front feet shod in combination with hind egg bar shoes (hEGGBAR), hind wide toe shoes (hTOE) and hind reverse shoes (hREVERSE). Data indicated that joint angles in the cervicothoracic junction were four times more likely to be significantly affected by the shoeing condition than in the back and sacrum. FORESHOD largely modifies the kinematics in comparison to REFSHOD or UNSHOD, with respectively a 6-11±1-2° (<em>P</em><0.001) increased cervicothoracic extension at walk and trot, and a 3-4±1° (<em>P</em><0.05) increased thoracolumbar flexion at trot.

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 first measured oral pH following five feedstuffs, (hay, haylage, unmolassed sugarbeet pulp, unmolassed alfalfa chaff and rolled oats), tested individually over five days.
