The aim of this study was to identify the main welfare issues likely to be encountered in five different categories of horses (Western riding horses, riding school horses, leisure horses, jumping horses, and endurance horses) kept in stabled housing systems. A total of 50 horses were evaluated using the Animal Welfare Indicator (AWIN) welfare assessment protocol for horses. Identified welfare issues in horses were inadequate box dimensions (52%, 26/50), insufficient quantity of bedding material (34%, 17/50), dirty bedding material (52%, 26/50), integument alterations (68%, 34/50), lameness (16%, 8/50), stereotypic behaviors (28%, 14/50), and negative response to human presence (24%, 12/50). The mean scores for alopecia, skin lesions, hardened spots at the mouth corners, horse grimace scale, and human-animal relationship tests in riding school horses were significantly higher (P<0.05; P<0.001) than for other categories of horses. The leisure horses exercised significantly less often (P<0.001) compared with other categories of horses. Additionally, important risks to welfare, identified across all groups of horses, were insufficient social interaction where 14 horses (28%) were unable to have any visual or physical contact with other horses. The results of this study provide the first analysis and valuable insight into the impact of the individual stable housing system on the welfare of different categories of horses in the Balkan region.</div></div>","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":"143 ","pages":"Article 105203"},"PeriodicalIF":1.3,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142348026","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}

Twelve horses underwent two examinations at least seven days apart. Horses were randomly assigned to receive midazolam intravenously (IV) (0.02mg/kg) or a placebo injection of saline (2-2.5mL IV). Five minutes later, detomidine (0.01mg/kg) and butorphanol (0.01mg/kg) were administered IV and horses were placed in standing stocks. A veterinarian blinded to the treatment protocol used a descriptive scoring system to assess degree of ataxia, acceptance of speculum, chewing on the speculum, headshaking, tongue movement, resistance to palpation, and eye appearance as related to the grimace score. During each examination, additional sedation of IV detomidine (0.006mg/kg) and butorphanol (0.006mg/kg) was administered at the discretion of the blinded practitioner to facilitate safe examination. At the second examination horses received the opposite treatment protocol and, following examination, a routine occlusal adjustment. Scores were compared using JMP software with a repeated measures mixed effects model, treatment as a fixed effect and horse and horse/treatment interaction as random effects. Significance was set at P<0.05. There were no significant differences in any of the single or overall sedation scores between treatment groups or within individual horses (P=0.3). Trends towards improvement of some assessed characteristics of sedation, including decreased tongue movement and less resistance to acceptance of speculum were observed.

This study aimed to characterize the fecal microbiome and the predicted functional profile of horses with and without aerophagia.

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.

Lysine acetylation has been shown to play a role in sperm capacitation in several species and the objective of this study was to detect and evaluate this process in the horse. Ejaculates of two stallions were collected and incubated in different conditions with deacetylase inhibitors to induce a hyperacetylation state. Although lysine acetylation was successfully detected in all experimental groups, sperm hyperacetylation could not be induced following incubation with deacetylase inhibitors. In addition, no hyperactivation was detected by kinematic sperm evaluation and tyrosine phosphorylation increased only in the positive control group. Treatments with high doses of deacetylase inhibitors increased acrosome reaction indicating a possible connection between induction of acrosome reaction and protein acetylation.

Moreover, the efficacy of treatments, measured from the FEC reduction compared to the control group, was weak (≤ 38.6 %).

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.
