Discrete-time survival models were performed for piglet survival and individual antimicrobial treatment as well as a linear regression model for piglet ADG from birth to slaughter. Medium (1 – 1.49 kg) and lightweight (&lt; 1.0 kg) piglets at day 4 had 2.26 and 4.04 times higher odds of dying (in terms of odds for discrete hazards), respectively, than heavyweight (≥ 1.5 kg) piglets. Barrows and antimicrobial-treated suckling piglets had 1.81 and 1.67 times, respectively, higher odds of dying than females and unmedicated piglets. The mean average daily gain from birth to slaughter was 714 g (SD 70.2 g). Pigs born to sows grew 29.2 g/day more than pigs born to gilts, and barrows grew 13.3 g/day better than females, but these results should be interpreted with caution because a considerable number of ear tags lost during the study could have led to selection bias of the pigs with a measured ADG. Altogether 756 piglets received at least one individual parenteral antimicrobial treatment. Antimicrobial-treated pigs were to a considerable extent medicated before weaning mainly for diarrhea and leg problems during two treatment peaks: before day 8 and around weaning. Lightweight piglets at day 4 had 2.35 and piglets born to gilts 1.56 times higher odds of becoming medicated with antimicrobials than heavyweight piglets and piglets born to sows, respectively. Half of the study piglets receiving antimicrobials were treated again later. In summary, our results show that lightweight piglets at day 4 had poorer survival, and they received more antimicrobial treatments than their heavier littermates. Further, gilt offspring were medicated more frequently.

This fact has driven the need to review biosecurity behaviours and perceptions of virus incursions on commercial poultry farms. This study used qualitative methods to evaluate farm managers’ perceptions of biosecurity and their implementation of measures as recommended by the Animal and Plant Health Agency (APHA). Thirteen farm managers across different regions of England and Wales were recruited between May and September 2023 to take part in the study. Qualitative semi-structured interviews were held with managers to discuss various topics relating to biosecurity and avian influenza (AI). Biosecurity measures being used across the farm by managers and staff were also observed to help understand biosecurity behaviours. Interviews were transcribed and analysed to identify themes and patterns amongst the data, along with extensive notes collated during the farm visits. Findings showed that farms’ use of biosecurity with respect to disinfection regimes and use of foot dips were both well cited and observed. Similarly, farm managers were all highly likely to refer to the use of farm-specific and shed-specific rubber boots, while also citing stricter requirements for visitors and delivery/maintenance. Biosecurity concerning the layout of the premises, fencing, access to changing rooms and the general age and maintenance of buildings and sheds required significant improvement across many farms. Additionally, farm managers expressed strong feelings of stress and anxiety in recent years, particularly those who had experienced an AI outbreak recently. We argue that factors such as risk perceptions, remits of control, feelings of responsibility and autonomy, and consequences on mental health, are all factors that can inform how farm managers respond to outbreaks and implement or sustain biosecurity on farms. A greater emphasis on providing regular and tailored training and educational resources for the industry would be beneficial as would further services focusing on reducing the burden on farmers’ mental health. This research provides insight into the application and shortcomings of biosecurity implementation on commercial poultry farms. It also identifies farmer perceptions and experiences shaping implementation on farms. However, this highlights that the onus for improving biosecurity cannot remain solely with farm managers and workers.

Options for reducing the risk of transmission of <em>M. bovis</em> from badgers to cattle include biosecurity measures, culling, and vaccination of badgers using the BCG vaccine. The use of vaccination as a control measure for tuberculosis (TB) in badgers has increased in recent years, with large-scale deployment in Ireland, and increasing use in England alongside a gradual phasing out of badger culling. Here we review evidence relating to the use of badger vaccination as a tool for controlling TB in badgers and cattle. Vaccination reduces the severity and progression of TB in badgers experimentally infected with <em>M. bovis</em> in laboratory studies, and significantly decreases the likelihood of naturally-acquired infection in free-living badgers in field trials. Modelling studies evaluating different strategies for controlling TB in badgers predict that badger vaccination will reduce TB prevalence in badger populations and lead to corresponding reductions in cattle herd disease incidence. While large scale field trials have not been undertaken to quantify the level of impact of badger vaccination on cattle bTB incidence in the UK, field studies in Ireland suggest that in some situations badger vaccination can result in beneficial disease outcomes in cattle which are comparable to those from badger culling. Attitudes to badger vaccination vary among stakeholder groups. Although members of the public are relatively positive about the benefits of vaccination, farmers are generally negative, due to concerns about practicality and effectiveness, along with a view that badger populations need to be controlled. The evidence published to date indicates that badger vaccination has the potential to contribute to the control of TB prevalence in wild badger populations and to form part of a wider strategy for controlling bTB. Future research should focus on investigating the effect of badger vaccination on bTB in cattle, along with understanding the impacts of vaccination in badgers in a broader range of ecological settings. Further understanding of the drivers of negative attitudes towards vaccination will nonetheless be crucial for incentivising and increasing the deployment of badger vaccination.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"238 ","pages":"Article 106464"},"PeriodicalIF":2.2,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453697","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}

The German Federal Veterinary Surgeon’s Association even calls for the establishment of an animal health database that combines slaughterhouse findings with health and farm data from already existing monitoring programs to create a comprehensive monitoring and surveillance tool. In an attempt to combine secondary health data from slaughterhouse findings, antibiotic use monitoring as well as biosecurity and husbandry evaluations into an integrated dataset, data from 18,593 fattening pig farms across Germany participating in the private sector Quality scheme for food (from 2018 to 2020) were harmonized at the half-year level and combined. As an example, the combined data was used to evaluate lung and tail lesion findings from abattoirs as indicators of animal health and welfare with descriptive analysis and mixed model approaches. Differences between abattoirs due to different data collection methods were taken into account by either considering the abattoir as a random effect or standardizing the prevalence data using abattoir means. The mean prevalence of lung lesions per half-year varied between 8.69 % and 9.78 %. The mean prevalence of tail lesion increased continuously from 0.65 % in the first half of 2018–1.04 % in the second half of 2020. Farm size, agricultural region, half-year and antibiotic treatment frequency were found to be associated (p &lt; 0.000001) with the prevalence of both lung and tail lesions. A lack of variance and specificity of the secondary biosecurity and husbandry evaluation data restricts the use of individual assessment criteria as well as biosecurity and husbandry indices (calculated from a subset of assessment criteria) in our analyses. We therefore used the data for a broad categorization of farms and it could be found, that the occurrence of a lower rating in any assessment criteria during farm evaluations is associated (p &lt; 0.000001) with a higher prevalence of lung and tail lesions, but the interpretation remains uncertain. The already existing data in the fattening pig sector can be used for the evaluation of animal health and welfare indicators to a large extent. Nonetheless, missing information, differences and changes (over time) in data collection methods introduce biases into the dataset. By improving the data quality and harmonizing collection methods, secondary animal health data could prove to be a useful tool in promoting animal health and welfare.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"238 ","pages":"Article 106469"},"PeriodicalIF":2.2,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143420597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic literature search was performed across PubMed, Web of Science, CNKI, Wanfang, and VIP databases, covering studies from the inception of the databases up to December 2023. A random-effects model was employed to estimate the global pooled prevalence of PAstV infection, and subgroup analyses were performed to evaluate the impact of different continents, years, detection methods, and sample types on the prevalence. Publication bias was assessed using a funnel plot and Egger's test. A total of 45 studies from 10 countries across three continents, involving 376 articles, were included in the meta-analysis. The global pooled prevalence of PAstV infection was found to be 28.19 % (95 % CI, 21.94 %-34.89 %).

Reducing and refining antimicrobial use (AMU) in farmed livestock is vital in slowing the development of AMR and preserving the efficacy of antimicrobials (AMs) in both humans and animals. Understanding the risk factors for AMU, however, is crucial to informing sustainable and effective farm AMU reduction and prudent use strategies. As a range of farm-level variables are likely to impact AMU, multidimensional exploratory analyses play a pivotal role in identifying direct and indirect factors influencing variation in AMU typically observed between dairy herds. This study used exploratory approaches to investigate whether typologies of dairy herds could be determined on the basis of farm characteristics, health parameters and management practices, and whether these herd types were differentiated by AMU. This study was conducted on 21 dairy herds in Wales, United Kingdom. Comprehensive surveys were administered and 224 usable variables regarding farm characteristics, herd health parameters and management practices were collated. AM sales data for each herd were used as a proxy for AMU. Multiple correspondence analysis (MCA) and hierarchical clustering on principal components (HCPC) were performed. The top 10 dimensions yielded by MCA explained 65.7 % of the total variance. Two data-driven typologies of dairy herds, produced from the first two cut-points of the HCPC dendrogram, were visualised and described. Here, five partitions of relatively homogeneous herds (herd types) were characterised and contrasted by 73 variable categories. Herd types were primarily constructed by variables focused on drying-off practices (and use of intramammary [IMM] AMs), herd size, stock purchasing and culling rates in addition to those concerning husbandry, disease management, grazing practices and veterinarian contact. Herd types characterised by performing blanket dry cow therapy (BDCT) used a higher mass of dry cow IMM AMs, EMA Category C and B AMs and had higher medium total AMU (mg/PCU) compared to herd types characterised by performing selective dry cow therapy (SDCT). From this study help untangle the myriad of factors influencing AMU at herd level and provide insight into the challenges of good AM stewardship. Strategies for sustainable reductions in AMU should be directed toward specific herd types identified, such as targeted interventions to implement SDCT. Multivariate exploratory approaches of dimensionality reduction and clustering are invaluable in elucidating the risk factors for AMU when utilising high-dimensional datasets.

Ninety percent of the workers interviewed were male, between 18 and 30 years old, with high school education, &lt; 7 years of experience, and learned their work in the slaughterhouse. In terms of human-animal interactions, we found that the nature of the tasks performed by each worker had an impact on their perceptions of pigs, particularly those involving work with live animals (outdoors) and stunning and bleeding (indoors). In addition, respondents show disapproval of cruel practices and a high level of awareness of pig pain and concern to alleviate it. However, there are neutral responses to statements that show some weakness in their feelings towards pigs. Forty per cent of respondents reported having at least one of the health problems and had suffered occupational accidents. The most common types of accidents were falls, cuts and animal aggression. These accidents were related to incorrect movements, especially in the morning, by personnel &gt; 40 years of age, with &gt; 7 years of experience, and the upper and/or lower extremities were most affected.

Based on this evidence, we conclude that adjustments of work break/rest intervals and improvements of working conditions are necessary to reduce fatigue, improve safety, and enhance work efficiency.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"238 ","pages":"Article 106462"},"PeriodicalIF":2.2,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143428689","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}
