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.

Bonded labour and donkey ownership in the brick kilns of India: A need for reform of policy and practice

Slavery, in the form of ‘debt-bondage’, is rife in Indian brick kilns, where the enforcement of labour laws is poor. Working equids support brick-kiln workers by transporting raw bricks into the kilns, but the situation of equids and their owners within the brick kilns is relatively unknown. We describe the welfare of donkeys (Equus asinus) owned under conditions of debt-bondage, examine the links between owner and donkey behaviour, and outline the living conditions of both donkeys and humans working in the brick kilns of Gujarat, India. We then explore the unique experience of debt-bondage by donkey owners, compare migration trends to those of non-donkey-owning workers and assess impacts on their children’s education. The physical and behavioural conditions of donkeys reflected that of their owners, creating negative feedback loops and potentially reducing productivity. All donkey owners experienced debt-bondage and were particularly vulnerable to unexpected financial loss. Donkey owners, unlike non-owners, migrated within their home state, enabling their children to attend school. Our work highlights the need for policy reform within the brick-kiln industry to acknowledge the pivotal role of working donkeys in supporting human livelihoods.

One welfare: Linking poverty, equid ownership and equid welfare in the brick kilns of India

The brick kilns in India are associated with extremely low pay, poor working conditions and a lack of regulation. Equids, however, may provide a route out of poverty by enabling workers to access a higher income. The relatively higher financial returns from healthy equids could also motivate welfare improvements. We used a mixed-methods approach including livelihoods questionnaires, semi-structured interviews and welfare assessments to investigate the links between poverty, equid ownership and equid welfare in the brick kilns of Ahmedabad, India. Whilst equid owners earned more than non-owners during the kiln season, the opposite trend was found for these workers for work conducted outside of the kilns during the off-season. Equid ownership was, however, strongly influenced by social factors and, within certain communities, equid ownership may be the only viable escape from extreme poverty. In terms of welfare, equid behaviour was better for owners with better financial security, likely due to the availability of resources. Equid health improved with longevity of ownership, suggesting that owners who view working with their equids as a long-term partnership are more likely to ensure their equids are kept in good health. For stakeholders aiming to improve both human health and equid welfare, a 'one welfare' approach which values the intrinsic connections between poverty and both equid ownership and equid welfare could greatly increase success.

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.

Science and knowledge of free-roaming donkeys - a critical review

The emergence of free-roaming donkey (Equus asinus) populations globally has brought novel challenges for conservationists, land managers, and those concerned about animal welfare. We provide a review of the scientific literature pertaining to the place and role of free-roaming donkeys from 1950 until 2020. Using quantitative and qualitative techniques, namely categorical and thematic analysis and critical discourse analysis, to review >100 articles, we critically examine the logics and rationales that are used to either support or denounce donkey presence in particular landscapes and discuss their place and role in different ecological contexts. Free-roaming donkeys are largely understudied and clouded by dichotomous points of view, different conservation agendas, and the presence of other species in donkey habitat. There is an important need for more in-depth, site-specific studies on free-roaming donkeys that draw on tools and techniques from across the social and natural sciences. Such efforts would offer a richer, more holistic, and comprehensive picture of free-roaming donkeys that consider both human and animal perspectives and the wider environment. This has important implications for generating long-term sustainable management solutions for free-roaming donkeys. © 2021 The Authors. The Journal of Wildlife Management published by Wiley Periodicals LLC on behalf of The Wildlife Society.

Documenting the welfare and role of working equids in rural communities of Portugal and Spain

Recently, the need for a more holistic approach to welfare assessment has been highlighted. This is particularly pertinent in the case of working equids who provide vital support for human livelihoods, often in low- to middle-income countries, yet suffer from globally low standards of welfare. This study aimed to provide insight into the welfare status and traditional use of working equids in rural Western European communities using the new EARS welfare tool, designed to provide a broad view of the welfare of working equids and the context in which they are found. Other questions on the topics of equid management practices, social transmission of expertise, environmental stressors, and traditions, alongside physical and behavioural welfare assessments were also included to explore the impact of these wide-ranging factors on an understudied population of working equids. The protocol was trialled on 60 working equid owners from communities in Portugal and Spain where, despite the decline in traditional agricultural practices and livestock keeping, donkeys and mules remain working animals. Many owners stated that the help donkeys provided was invaluable, and donkeys were considered to be important for both farming and daily life. However, participants also recognised that the traditional agricultural way of life was dying out, providing insights into the traditional practices, community structure, and beliefs of equid owners. Questions investigating the social networks and social transfer of information within the villages were effective in finding local sources of equid knowledge. Overall, welfare was deemed fair, and the protocol enabled the identification of the most prevalent welfare problems within the communities studied, in this case obesity and the use of harmful practices. The findings suggest that the new protocol was feasible and detail how contextual factors may influence equid welfare. Increasing understanding of the cultural context, social structure, and attitudes within a community, alongside more traditional investigations of working practices and animal management, may, in the future, help to make equid welfare initiatives more effective.
