This article reports a scoping review of research that is workplace-based and that provides information on the reported benefits or problems of allowing employees' pets at work. The databases Scopus, Discover and Google Scholar were searched with the initial search terms \"<i>pets</i> AND <i>workplace</i> AND <i>research</i>.\" Results were reviewed initially by title to remove items where, for instance, \"PET\" was used as an acronym. Studies were included if they provided information on research into human well-being and/or work or task performance and pets at work. This included research into the presence of pets while working from home, as the home can be considered a workplace in this situation. A total of 189 papers on pets at work were identified from the searches. The abstracts were reviewed and papers that did not report research into the benefits and challenges of employees' pets at work were excluded, leaving 31 results. The majority of studies used survey methods and did not include validated psychometric measures of key variables including stress. Findings indicated that the presence of employees' pets at work may reduce stress and lead to more positive work-related attitudes, but these findings may not apply to all employees or all workplaces. Negative aspects of pets in the workplace include health risks to humans and animals, cultural concerns and dislike or fear of some animals, and the proportion of participants who raised these concerns or agreed with them varied widely between studies. However, there is little evidence on the prevalence of risks or how they are addressed, and there was no data on how work performance, absenteeism or staff turnover were related to pet-friendly policies at work. More research is required, and some directions for future research are suggested.</p>","PeriodicalId":19322,"journal":{"name":"New Zealand veterinary journal","volume":" ","pages":"307-316"},"PeriodicalIF":1.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141982869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Half the animals were challenged with an oral dose of 20,000 larvae of <i>Ostertagia ostertagi</i> and <i>Cooperia oncophera</i> once a week for 3 weeks and half were unchallenged. Five weeks after the last dose, seven infected and nine uninfected animals were treated with an oral anthelmintic (AHC) and data collected for a further week. Accelerometer data were classified into minutes per day eating, ruminating, in moderate-high activity or in low activity.

They ruminated up to 9 (95% HDI = 2-15) minutes/day more and ate up to 10 (95% HDI = 2-19) minutes/day more than control calves that were not treated with AHC. The effect of AHC on time spent in each behaviour differed between infected and uninfected calves and increased the coefficient of dispersion of the behavioural data.</p><p><strong>Conclusions and clinical relevance: </strong>Small differences in animal behaviour can be measured in calves with GIP. However, to use this to target treatment, further validation studies are required to confirm the accuracy of behavioural classification and understand the complex drivers of animal behaviour in a dynamic and variable pasture-parasite-host environment.</p>","PeriodicalId":19322,"journal":{"name":"New Zealand veterinary journal","volume":" ","pages":"275-287"},"PeriodicalIF":1.1,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141161972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
