Background: Equine herpesviruses (EHV) are among the most diagnosed infectious diseases of equids. The type and clinical presentation of herpesvirus infection in donkeys can differ to that of horses. There is especially limited donkey-specific literature regarding gamma herpes viruses.

Objectives: The aim of this study was to retrospectively review positive herpesvirus cases in equids across 10 sanctuary sites in the south of England, examine the type of viruses identified and associated clinical manifestations.

Study design: Retrospective case review.

Methods: Identification of herpesvirus positive q-PCR results over a 15-month period from January 2023 to March 2024 through laboratory records. All descriptive statistical analysis was performed using R v4.2.1 and RStudio v2023.06.1.

Results: A total of 21 positive test results from 20 individual cases were examined. The population consisted of 19 donkeys and 1 pony, with ages ranging from 7 to 31. Sample types included nasopharyngeal, nasal, and ocular swabs, eye tissues and cerebrospinal fluid (CSF). EHV-2 was identified most frequently (12/21), including once in CSF, followed by EHV-8, formerly known as asinine herpesvirus-3, (8/21) and then EHV-5 (1/21). Overall, 43% (9/21) of positive cases were associated with outbreaks of disease. Serous nasal discharge was the most reported presenting sign across all positive cases (9/21), found also in 88% (7/8) of EHV-8 cases. Ultimately 70% of all positive cases resolved, 30% were euthanised, and of those 83% (5/6) had concurrent or chronic illness.

Main limitations: Due to the study design, the dataset available for analysis is limited. Consequently, only descriptive statistics are included.

Conclusion: Herpesvirus positive cases in donkeys and ponies at The Donkey Sanctuary, UK are often associated with outbreaks and a variety of clinical manifestations, from mild respiratory signs to severe neurological, respiratory, and ophthalmic disease. Screening for EHV-1 and EHV-4 in acutely unwell donkeys may overlook virus types associated with severe and infectious disease.

Mule trains to mountain roads: the role of working mules in supporting resilient communities in the Himalayas

Working equids play a central role in mountainous communities, but their work often goes unnoticed by the wider world, with sparse documentation of their role, value, or welfare – a state which often extends to their human counterparts. Communities living in the remote Manaslu Valley, Nepal, face a number of uncertainties, including extreme weather events due to the seasonal monsoon and, more recently, the construction of a new road network. Using semi-structured interviews, questionnaires, and Equine Assessment Research and Scoping (EARS) welfare assessments, we outline the specific role of pack mules in supporting the lives of local people, explain the nuanced links between human experience and mule welfare, and gain insight into how people living in this volatile environment manage uncertainty and risk. Mule work was felt to be the ‘only option’ for a sustainable livelihood for most mule owners although, in some cases, mules had enabled respondents to diversify their income. Mule owners with more husbandry experience did not own mules in more positive behavioural states, which may suggest a lack of generational knowledge and support networks. Short-term ongoing risks, such as the monsoon or unstable tracks, had a larger impact both financially and emotionally than the long-term but distant implications of the road construction. Mule owners must constantly balance the risk of working during the monsoon season, when conditions are treacherous but pay was higher, with losing valuable income but keeping themselves and their mules safe; they do, however, have a more mobile option for employment than non-owners. Mules enable a level of resilience and agility for communities living with constant uncertainty and change, which is only beginning to be recognised formally within the sustainable development sphere. Integration of animal welfare into the SDGs would allow humanitarian aid initiatives to strengthen support networks around working equids, which would greatly benefit the mules and humans alike.

What is a working equid? Analysis of current terminology and a suggested definition

Equids are engaged in myriad types of work across the world, with contexts and industries varying widely between high-, middle- and low-income countries as classified by the World Bank. Through a comprehensive abstract search and literature review, we examined the usage and context of terms associated with working equids in high-income countries (HICs), upper-middle-income countries (UMICs), lower-middle-income countries (LMICs), and low-income countries (LICs). Analysis showed that the search term used was significantly associated with World Bank country income classification. All search terms except two returned a significantly higher number of papers for higher-income countries compared to lower-income countries. The two exceptions were “working equid” and “draft equid”, which returned significantly more papers for lower-income countries than higher-income countries. Both terms also returned papers from high-income and upper-middle-income countries, but these were always in the context of low-resource settings and rural or marginalised communities, of which we provide examples in the discussion. We propose that the term “working equid” should be used to describe “any equid engaged in physical labour that provides a significant or direct contribution to the economic livelihood, sustenance or support of the owner/user’s family, typically within a low resource setting”. Our review highlights the intricate interplay between socioeconomic factors and examines how equids are described in the literature. The lack of a universally accepted definition leads to challenges in policy formulation, resource allocation, and welfare standards development, particularly in LMICs and LICs where working equids are crucial to livelihoods. This study underscores the need for a more inclusive and comprehensive approach to terminology, advocating for future research to bridge linguistic and cultural gaps in understanding working equids globally. Such efforts are vital for equitable and effective welfare standards and policy development for these animals.

Hoof Work: The Feminisation of Donkeys in Ethiopia

This article explores how gendered divisions of labour manifest across species lines. It applies a feminist, more-than-human intersectional approach, building on previous work on animal labour. The vital labour donkeys do with and for humans and their contributions to multispecies societies have been under-recognised and under-theorised. Drawing on empirical research conducted in central Ethiopia on the human-donkey relationship, findings reveal the multiple ways human gender and class coalesce to shape the kinds of labour performed and social relations among women, men, and donkeys across urban and rural environments. At the nexus of these intersecting forces, equivalence is drawn, by research participants themselves, between women and donkeys. Women and donkeys are aligned and othered, differentiated from men, a dynamic that results in the feminisation of donkeys and mutual marginalisation of women and donkeys and exposes male violence perpetrated on both groups. The article contributes empirical insights into human-donkey relations and interspecies labour and offers theoretical considerations of more-than-human intersectionality.

Objective assessment of chronic pain in donkeys using the Donkey Chronic Pain Scale

Objective

To clinically evaluate previously developed pain scales [Donkey Chronic Pain Composite Pain Scale (DCP-CPS), Donkey Chronic Pain Facial Assessment of Pain (DCP-FAP), and combined Donkey Chronic Pain Scale (DCPS)], including behavioural and facial expression related variables, for the assessment of chronic pain in donkeys.

Study design

Prospective, blinded clinical study.

Animal population

A group of 77 donkeys (34 patients and 43 healthy control animals)

Methods

Animals were assessed by two observers that were blinded to the condition of the animals.

Results

Both DCP composite pain scale (CPS), DCP facial assessment of pain (FAP) and resulting Donkey Chronic Pain Scale (DCPS) scores showed good inter-observer reliability (Intra Class Correlation (ICC) coefficient = 0.91, confidence interval (CI) = 0.86–0.95, p < 0.001; ICC = 0.71, CI = 0.50–0.83, p < 0.001 and ICC = 0.84, CI = 0.72–0.91, p < 0.001 respectively). All scores (DCP-CPS, DCP-FAP and the resulting combined DCPS) were significantly higher for patients compared to controls at all time points (p < 0.001 for all three scales). Sensitivity and specificity for identification of pain (cut-off value > 3) was 73.0 and 65.1% for DCP-CPS, while for DCP-FAP this was 60.9% and 83.3%, respectively. For the combined DCPS, sensitivity was 87.0% and specificity 90.9% (cut-off value > 6).

Conclusions and clinical relevance

The DCPS, based on behavioural and facial expression-based variables, proved a promising and reproducible tool to assess different types of chronic pain in donkeys. The combination of behavioural and facial expression-based variables showed the best discriminatory characteristics in the current study. Further studies are needed for refinement of these tools.

“We forgot about the donkeys!” An institutional analysis of the shift in animal welfare from direct implementation towards advocacy-based programming

Shifts from direct implementation to advocacy-based programming have been documented across many non-governmental organisation (NGO) sectors, including animal welfare. Semi-structured interviews with 32 staff from different positions within animal welfare NGOs explored recent programming changes. Maintaining a balance between direct implementation and advocacy-based activities emerged as a strong theme. The findings suggest that risks are associated with both the direct implementation status quo and transitioning to an advocacy-based focus. Risks of the former include treating symptoms rather than root causes of welfare problems. Organisational change can be disruptive and necessitates realignment of core competences, in turn influencing NGO mission. Identified risks of transition include loss of individuals whose values fail to align with new programming directions, increased upwards accountability requirements for accessing institutional donors and difficulties when phasing out direct implementation approaches. Whilst having to be dynamic, NGOs need to evaluate the risks associated with programming decisions, considering their vision, mission and staff identity in order to ensure that welfare programming is as effective as possible.

First report of Besnoitia bennetti in Irish donkeys: an emerging parasitic disease in Europe

Background 

This is the first report of Besnoitia bennetti in donkeys in Ireland. B. bennetti, an apicomplexan protozoan parasite specifc to equids, is an emerging pathogen in Europe. This parasite forms chronic intracytoplasmic cysts in cells of the mesenchymal lineage, mainly fbroblasts, in the skin, sclera and mucosa. Clinical signs in afected equine hosts vary from mild to severe debilitating disease. Little is known of the phylogeny, epidemiology or transmission of B. bennetti infection in donkeys, mules or horses. 

Case presentation 

Two cases of besnoitiosis in donkeys are presented. Both donkeys were born and raised in the south west of Ireland. The first case was a 2.5-year-old donkey that had a suspect sarcoid removed, while the second case, a 2-year-old donkey, had a biopsy of nodular dermatitis of the muzzle. Diagnosis was made by histopathology and the parasite species, B. bennetti, was confirmed by PCR followed by sequencing and microsatellite analysis. Both donkeys had high antibody titres against Besnoitia spp. Small (0.5 mm) scleral, conjunctival and dermal cysts over the muzzle were subsequently observed in both animals. Treatment with trimethoprim sulfadiazine for 30 days did not lead to clinical resolution. The fndings are compared to the cases of besnoitiosis in donkeys reported in the past 10 years throughout Europe. 

Conclusions 

Besnoitiosis should be considered as a differential diagnosis for chronic skin disease particularly in cases of cutaneous masses, non-pruritic dermatitis, and dermatitis that is not responsive to treatment in donkeys and other equids. Future studies are needed to investigate the prevalence of the disease in Irish donkeys, the spread of the disease and the potential impact on the health and welfare of the donkeys.

Sustainability in NGO programming: A case study of working equid welfare organizations

The sustainability of NGO initiatives has become a criterion by which to judge the success of programming. This study explores the conditions needed in order to achieve sustainable change by focusing on a sector that has recently experienced this shift towards more sustainable, interdisciplinary programming: that of working equid (animal welfare) NGOs. Semi-structured, in-depth interviews with 32 NGO staff working for 8 different animal welfare NGOs across 13 countries were conducted. These interviews covered potential barriers and avenues to success in producing sustainable working animal welfare improvements. Thematic analysis revealed consistent themes across contexts and NGOs. Approaches perceived as creating sustainable outcomes were ones that tailored initiatives to local contexts, focused on changing human behaviour, worked with key community contacts, built capacity in local infrastructure, combined approaches, and had comprehensive exit strategies. Barriers to sustainability included lack of continuity, short funding cycles and unpredictable external factors. Consideration of these conditions for designing effective future initiatives is recommended across the wider not-for-profit sector.

Invisible animals: Exploring public discourses to understand the contemporary status of donkeys in Britain

Established representations of donkeys in western literature and popular culture have often been negative, portraying the animals as stupid, inept, and bad tempered. To understand whether such representations are reflected in contemporary understandings of donkeys, we constructed a digitized body of texts (a corpus) from contemporary (public-facing) news articles and (public-produced) social media posts about donkeys, which we analyzed using quantitative and qualitative language analysis techniques drawn from corpus linguistics and discourse analysis. We supplemented this with focus groups conducted with members of the public to gather insights and reflections on key patterns of representation in two key news texts identified in the linguistic analysis. This combined approach, which is novel in its application to animal welfare topics, revealed that donkeys are most commonly represented as figures of entertainment, ridicule, and as victims of hardship and suffering (i.e., animals in need). We argue that such representations can sideline, obscure and “invisibilize” the real animals, leading to persistent misunderstandings and false conceptions about donkeys, which are further perpetuated through language use and can be difficult to disrupt and change. These findings have important implications for animal welfare, education programs, and public communication about donkeys. Finally, we highlight areas where incorrect, unhelpful, and potentially damaging representations can be challenged by those seeking to improve the contemporary status of donkeys.

Belief in animal sentience and affective owner attitudes are linked to positive working equid welfare across six countries

Belief in animal sentience and the quality of human-animal relationships play a significant role in animal welfare. However, the link between an individual animal’s welfare and the beliefs and emotional connection of the owner to the animal is understudied and focussed on single cultures, limiting generalisability. In this study, we explored potential links between owner attitude, beliefs in animal sentience, and working equid welfare across four continents. This study used a welfare assessment protocol alongside a questionnaire exploring owner attitudes to assess 378 participants across six countries. Overall, the general health status and body condition of equids belonging to owners with an affective (versus instrumental) perspective and those owners who believed that their equids could feel emotions, were significantly better. Equids belonging to owners who believed that their animals could feel pain were also significantly less likely to be lame. Potential causal relationships between factors and theories explaining these beliefs are discussed. These results can inform future welfare initiatives by highlighting the importance of the human–equid relationship and the role that beliefs regarding animal sentience play in influencing equid welfare.
