Magnetic resonance imaging (MRI) is the gold standard in SM diagnosis. However, it is desirable to establish clinical predictors that can identify CKCSs with a large clinical syrinx that needs treatment, as some owners cannot afford or lack access to MRI. The aims of the study were to investigate owner-reported clinical signs of SM and clinical predictors of a large clinical syrinx, using predictive values of significant signs, individually and in combinations. Eighty-nine CKCSs participated in this retrospective study. Based on MRI diagnosis, dogs were distributed into three groups: CM without syrinx or with a maximum transverse width < 2 mm (n = 13), CM with small syrinx 2.00-3.99 mm (n = 26) and CM with large syrinx ≥4 mm (n = 50). A structured investigator-owner interview using a standardized questionnaire was used to collect data regarding clinical signs of CM and SM.

The animals move over large areas in varying terrain and often in challenging weather conditions. Winter crises, such as difficult grazing conditions caused by icing or large amounts of snow, are survival bottlenecks for reindeer. Calves are especially vulnerable, and many may die from starvation during winter crises. Predation and starvation are the predominant narratives to explain losses, however, carcasses are difficult to find and often little remains after scavenging and decay. Documentation of the causes of death is therefore scarce. In this study, we investigated the cause of reindeer mortality in Troms and Finnmark, Nordland and Trøndelag during 2017–2019. Necropsies (n = 125) and organ investigation (n = 13) were performed to document cause of death. Body condition was evaluated using visual fat score and bone marrow fat index. A wide range of causes of death was detected. The diagnoses were categorized into the following main categories: predation (n = 40), emaciation (n = 35), infectious disease (n = 20), trauma (n = 11), feeding related disease (n = 5), neoplasia (n = 4), others (n = 6) and unknown (n = 17). Co-morbidities were seen in a number of diagnoses (n = 16). Reindeer herders are entitled to economic compensation for reindeer killed by endangered predators, but a lack of documentation leads to a gap between the amount of compensation requested and what is awarded. An important finding of our study was that predators, during winter, killed animals in good as well as poor body condition. Emaciation was also shown to be associated with infectious diseases, and not only attributable to winter grazing conditions. This study highlights the importance of examining dead reindeer to gain knowledge about why they die on winter pasture. The work presented herein also shows the feasibility and value of increased documentation of reindeer losses during winter.","PeriodicalId":7181,"journal":{"name":"Acta Veterinaria Scandinavica","volume":"15 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139095407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A questionnaire survey was emailed to 63 dog owners whose dogs had been diagnosed with periodontitis, received dental cleaning at the University Animal Hospital, Swedish University of Agricultural Sciences and were given tooth brushing instructions. The survey was supplemented by telephone interviews, resulting in a 57% response rate. The study presents dog owners' routines, experiences, attitudes, and motivation regarding tooth brushing. Approximately 42% brushed their dogs' teeth daily while others did so less frequently or not at all. Reported challenges, such as uncooperative dogs and difficulty establishing a routine, may explain infrequent brushing. While the study suggests that owners of dogs with periodontitis tend to follow dental care recommendations better than the general dog owner population, it also reveals that preventive care is inadequate for more than half of the dogs. Given the high prevalence of periodontitis, there's a need for resources to address infrequent tooth brushing.

The responsible authorities launched a control programme to eradicate the infection. The aim of the current study was to understand (i) how Swedish pig farmers have perceived the information issued by authorities and other stakeholders since the discovery of ASF in wild boar, (ii) which risks they see for introducing the infection to their farm, (iii) what biosecurity measures they have taken on their farms, and (iv) their outlook on the future. Such information is important for evaluating the effectiveness of the early stages of ASF control in Sweden. A questionnaire was designed and distributed to members of the Swedish pig producers’ organisation. A total of 155 farmers responded to the survey (response rate 36%). Almost all respondents had received general information about ASF (91%, n = 138), and 72% (n = 109) had received information about how they can protect their farm from ASF introduction. A majority (87%, n = 118) thought the information was easy to understand, 90% (n = 137) that is was relevant, and 77% (n = 117) that they currently did not lack any information. If given the resources necessary, 58% (n = 84) of the farmers would like to take additional measures such as fencing, and heavily reduce or eradicate the wild boar population. Wild boars were considered the greatest risk for introduction of ASF into their herd (39%, n = 57), followed by people (30%, n = 44), and transports (16%, n = 23). Many farmers (66%, n = 88) had a positive outlook on the future, and 89% (n = 127) have not changed their plans for the future since the ASF outbreak. The responding farmers were in general satisfied with the information received in the beginning of the ASF outbreak. The majority have a positive outlook on the future and the outbreak has not caused them to change their plans. Actions that were highlighted as important to safeguard Sweden's pig production included measures to control the wild boar population.","PeriodicalId":7181,"journal":{"name":"Acta Veterinaria Scandinavica","volume":"7 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138743373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
