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.

Therapeutics in veterinary care of the donkey

Knowledge of donkey-specific disease presentation, behaviour, anatomy and physiology is beneficial when choosing appropriate medications and routes of administration in this species. While many selected therapeutic agents will be the same as those used in the horse, being aware of certain nuances will ensure that the donkey receives the best possible care. Clinicians and owners alike may benefit from drug administration tips. As there are limited drugs licensed for use in the donkey, use of the prescribing cascade is usually warranted. This article mentions the use of therapeutics in mules where appropriate.

Entanglement, autonomy and the co-production of landscapes: relational geographies for free-roaming ‘feral’ donkeys (Equus asinus) in a rapidly changing world

For thousands of years, the donkey (Equus asinus) has played an essential role in human society, underpinning the earliest forms of civilisation, facilitating critical trade networks, contributing to agricultural development, construction and mining. However, with the rise of motorised transport and agricultural machinery, the donkey was gradually turned loose in many places, and left free to roam. The emergence of freeroaming donkey populations has brought novel challenges for conservationists, land managers and animal welfarists alike. As non-native species that live and breed independently in large numbers, free-roaming donkeys appear as an ambiguous indeterminate group of wild-domestic creatures that sit uneasily with rapidly changing landscapes, societies and economies. This paper explores the status of free-roaming donkeys and the ongoing tension between the wild and the domestic, including the binary thinking underpins it and produces donkeys as non-native or ‘out of place’. Using a relational approach and paying attention to the various ways in which freeroaming donkeys are entangled and embedded within cultural historical landscapes, this paper suggests how donkeys might be re-examined in terms of their ‘entangled autonomy’, building on recent interventions in ‘wild’ animal geographies and ‘feral’ political ecologies. In doing so, it reframes the debate around the status of freeroaming donkeys and posits an argument for how they might be considered to ‘belong’ or have legitimacy within these landscapes, suggesting that more attention needs to be given to the spaces and places that donkeys create or contribute to, as well as those they disrupt and challenge.

Donkeys in transition: changing use in a changing world

Donkeys have a long history in the development of human societies. Typically referred to as a beast of burden, traditional uses for donkeys have included the transportation of goods and people, use in agricultural and forestry activities, to access water, and provide citizens in low- and middle-income countries a means of making an income for communities.

However, the rise of mechanization, the development of modern farming techniques, and the increasing availability of motorized vehicles have led to donkeys and mules becoming redundant from traditional roles in many parts of the world.

We provide examples of where donkeys have successfully transitioned from traditional roles to new, non-traditional roles in Europe and North America, and demonstrate that, although the roles and use of donkeys and mules are changing in a rapidly developing world, we can learn lessons from the past and apply them to current challenges.

As the need for working equids declines in transport and agriculture, they still hold great value for recreational, therapeutic, and environmentally friendly methods of animal traction.

‘Don’t put the cart before the mule!’ Challenging assumptions regarding health-related treatment practices of working equid owners in Northern India

This paper challenges assumptions that the health management of working equids among some of India’s poorest communities is mainly dependent upon income, economic influence, or access to veterinary services. Using a mixed-methods approach, hierarchies of treatment practices are revealed through an examination of the ‘lived experience’ of equid owners in brick kilns and construction sites in northern India. Semi-structured interviews with 37 equid owners and corresponding livelihood surveys, combined with data from two focus groups with professional animal health practitioners and the welfare data of 63 working equids collected using the Equid Assessment, Research, and Scoping (EARS) tool, contributed to the findings of the study. Four principal influencing factors were found to affect the decision-making practices of equid owners. Infrastructural factors, community characteristics and experience, owners’ characteristics and experience, and economic factors all impact the belief structures of equid owners. However, without verifying the validity of the treatment measures being employed, some animals are at risk from hazardous treatment behaviours. By understanding decision-making using the theory of planned behaviour, the findings of this study can provide a crucial contribution to informing future interventions involved in the health management and welfare of working equids.

Endoparasite control for donkeys in the UK

The prevalence of endoparasites, their control and clinical relevance in donkeys can often cause confusion and concern to vets and owners alike. While donkeys can be affected by the same parasite species as horses, infection characteristics, presenting signs and symptoms of disease can differ. Donkeys do not always show obvious signs of disease until it is severe so it is important to know what to look out for when clinically assessing a donkey and how best to diagnose potential infection with parasites. There is a limited selection of anthelmintic products available for use in the donkey, so prescribing using the cascade is sometimes warranted. Careful consideration should be given to the choice and frequency of anthelmintic treatments in order to balance controlling disease with preserving anthelmintic efficacy.

Quantifying poor working equid welfare in Nepalese brick kilns using a welfare assessment tool

Background

Across Asia the brick-kiln industry is expanding. In Nepal, urban dwelling has increased in recent years, raising requirement for low-cost, mass produced bricks to meet the population needs. Working equids (WEs) play a key role in non-mechanised kilns. Assessing the welfare of these equids is the starting point to addressing concerns. In line with One Welfare principles, the health and welfare of animals, people and the kiln environment are interlinked.

Materials and methods

In December 2019, 119 WEs were assessed in seven brick kilns in three districts of Nepal, using the Equid Assessment Research and Scoping tool, developed by The Donkey Sanctuary. The objective was to measure welfare at the start of the brick kiln season.

Results

Horses were the predominant species of WE. Hazardous housing and environments were seen in all kilns. Behaviour responses were mixed. Owner responses and animal examination indicated poor working conditions. Signs of harmful practice were evident in most animals. The majority were underweight, with poor general health, skin alterations and musculoskeletal issues.

Conclusion

The welfare of equids prior to starting brick kiln work is poor, posing significant concerns for the actual working period. Intervention to enhance health and welfare is required.

The effectiveness of faecal removal methods of pasture management to control the cyathostomin burden of donkeys

Background

The level of anthelmintic resistance within some cyathostomin parasite populations has increased to the level where sole reliance on anthelmintic-based control protocols is not possible. Management-based nematode control methods, including removal of faeces from pasture, are widely recommended for use in association with a reduction in anthelmintic use to reduce selection pressure for drug resistance; however, very little work has been performed to quantitatively assess the effectiveness of such methods.

Methods

We analysed data obtained from 345 donkeys at The Donkey Sanctuary (Devon, UK), managed under three different pasture management techniques, to investigate the effectiveness of faeces removal in strongyle control in equids. The management groups were as follows: no removal of faeces from pasture, manual, twice-weekly removal of faeces from pasture and automatic, twice-weekly removal of faeces from pasture (using a mechanical pasture sweeper). From turn-out onto pasture in May, monthly faecal egg counts were obtained for each donkey and the dataset subjected to an auto regressive moving average model.

Results

There was little to no difference in faecal egg counts between the two methods of faecal removal; both resulted in significantly improved cyathostomin control compared to the results obtained from the donkeys that grazed pasture from which there was no faecal removal.

Conclusions

This study represents a valuable and unique assessment of the effectiveness of the removal of equine faeces from pasture, and provides an evidence base from which to advocate twice-weekly removal of faeces from pasture as an adjunct for equid nematode control. Widespread adoption of this practice could substantially reduce anthelmintic usage, and hence reduce selection pressure for nematode resistance to the currently effective anthelmintic products.

Influence of dental correction in nociceptive tests response, fecal appearance, body condition score and apparent dry matter digestibility of Zamorano-Leonés donkeys (Equus asinus)

The influence of dental correction on nociceptive (pressure) test responses, fecal appearance, BCS, and apparent digestibility coefficient for DM was studied in 18 Zamorano-Leonés donkeys, an endangered local breed from the Zamora province in Spain. For this purpose, donkeys were divided into 2 homogeneous control and treatment groups, based on age, BCS, and dental findings. On d 1, 45, 90, and 135, BCS and nociceptive test responses were evaluated in all donkeys. Feed and fecal samples were collected from all donkeys for 3 consecutive days, starting at each of the aforementioned days. Apparent digestibility coefficient for DM was estimated, using ADL as an internal marker. A progressive decrease of positive nociceptive test responses was observed from d 1 up to 90 (P < 0.01) in the treatment group. No difference between groups was observed for BCS. However, BCS at d 90 was greater (P = 0.018) than observed on d 1 or 45, indicating a time influence. Concerning apparent digestibility coefficient for DM, there were differences among collection days in apparent digestibility coefficient for DM (P < 0.05). No differences in fecal appearance were observed between treatments or collection days. This study highlighted the importance of regular dental care for not only Zamorano-Leonés donkeys but also the equid population, in general, to improve their welfare.

Cultural “blind spots,” social influence and the welfare of working donkeys in brick kilns in Northern India

Non-governmental organizations (NGOs) work across the globe to improve the welfare of working equids. Despite decades of veterinary and other interventions, welfare issues persist with equids working in brick kilns. Engagement with all stakeholders is integral to creating abiding improvements to working equid welfare as interventions based purely on reactive measures fail to provide sustainable solutions. Equid owners, particularly those in low to middle-income countries (LMICs), may have issues such as opportunity, capacity, gender or socio-economic status, overriding their ability to care well for their own equids. These “blind spots” are frequently overlooked when organizations develop intervention programs to improve welfare. This study aims to highlight the lives of the poorest members of Indian society, and will focus on working donkeys specifically as they were the only species of working equids present in the kilns visited. We discuss culture, status, religion, and social influences, including insights into the complexities of cultural “blind spots” which complicate efforts by NGOs to improve working donkey welfare when the influence of different cultural and societal pressures are not recognized or acknowledged. Employing a mixed-methods approach, we used the Equid Assessment Research and Scoping (EARS) tool, a questionnaire based equid welfare assessment tool, to assess the welfare of working donkeys in brick kilns in Northern India. In addition, using livelihoods surveys and semi-structured interviews, we established owner demographics, socioeconomic status, ethnicity, religion and their personal accounts of their working lives and relationships to their donkeys. During transcript analysis six themes emerged: caste, ethnicity, inherited knowledge; social status, and impacts of ethnic group and caste; social status and gender; migration and shared suffering; shared suffering, compassion; religious belief, species hierarchy. The lives led by these, marginalized communities of low status are driven by poverty, exposing them to exploitation, lack of community cohesion, and community conflicts through migratory, transient employment. This vulnerability influences the care and welfare of their working donkeys, laying bare the inextricable link between human and animal welfare. Cultural and social perspectives, though sometimes overlooked, are crucial to programs to improve welfare, where community engagement and participation are integral to their success.
