RESUMO
Donkeys (Equus asinus) are facing a global crisis. Their welfare, and even survival, is being compromised as the demand for their skins increases. This demand is driven by the need to supply raw materials to produce ejiao, a Traditional Chinese Medicine made from collagen extracted from donkey skins. Since there is no productive chain for donkey skin production outside of China, the global trade is an entirely extractive industry that has resulted in the decimation of some local donkey populations. The donkey skin trade is demonstrably unsustainable, from the ethical issues associated with poor welfare, to the biosecurity and human health risks the trade poses; and it violates both legal frameworks and moral expectations at both a national and global level.
RESUMO
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.(AU)
Os jumentos têm uma longa história no desenvolvimento das sociedades humanas. Normalmente referidos como bestas de carga, seus usos tradicionais incluem o transporte de pessoas e bens, atividades agrícolas e florestais, acesso a água, assim como oferecer uma forma de rendimento para comunidades em países de rendimento baixo e médio. No entanto, o aumento da mecanização, o desenvolvimento de técnicas agrícolas modernas e maior disponibilidade de veículos motorizados fizeram com que os jumentos e os muares se tornassem desnecessários nos seus papéis tradicionais em muitas partes do mundo. Neste artigo os autores fornecem exemplos onde os jumentos fizeram a transição, com sucesso, dos papéis tradicionais para novos papéis não tradicionais, tanto na Europa como na América do Norte; e demonstramos que, embora o papel e o uso de jumentos e muares estejam mudando num mundo em rápido desenvolvimento, podemos aprender lições com o passado e aplicá-las aos desafios atuais. À medida que diminui a necessidade de equídeos de trabalho no transporte e na agricultura, eles ainda têm grande valor no que toca a fins recreativos, terapêuticos e ecológicos no uso de tração animal.(AU)

Donkeys (Equus asinus) face a global crisis. The health, welfare, and even survival of donkeys are being compromised as the demand for their skins increases. It is driven by the production of ejiao, a traditional Chinese remedy believed by some to have medicinal properties. It is estimated that the ejiao industry currently requires approximately 4.8 million donkey skins per year. Since there is no productive chain for donkey skin production outside of China, the activity is extractive and has resulted in the decimation of donkeys. Gestation is 12 months in donkeys, increasing the risk of extinction if such practices are not controlled. In this scenario, the donkeys are collected (purchased for low prices, stolen, and collected from the side of the roads) and are then often transported for long distances, usually without water, food, or rest. The trade, in Brazil, poses significant biosecurity risks, particularly because examinations are rarely conducted and therefore infectious diseases, such as glanders and infectious anemia, remain undetected. Furthermore, in chronic stress situations, the immune system is suppressed, increasing the biosecurity risk, especially because donkeys are a silent carrier of diseases. Rarely there is traceability with animals from different origins being put together in "fake farms", before being delivered to slaughterhouses. The opportunistic strategy of collecting animals, or buying for low prices, keeping them without access to food and veterinary assistance, is what makes this trade profitable. Our experience in donkey welfare and the global skin trade suggest that it will be enormously challenging and cost-prohibitive to run a trade at the standards required to be considered humane, sustainable, and safe. Although donkeys are being blamed for the involvement in road accidents, it is not an ethical solution to maintain this trade as an alternative. Moreover, the ecological role of donkeys in native ecosystems has not been elucidated, and some studies indicate they could even have a positive effect. Regardless of the future the donkeys will have; we must guarantee a life with the least dignity to the animals under our responsibility.(AU)
Os jumentos (Equus asinus) estão enfrentando uma crise global. A saúde, o bem-estar e até a sobrevivência dos jumentos estão sendo comprometidos à medida que a demanda por suas peles aumenta. A atividade é impulsionada pela produção de ejiao, um remédio tradicional chinês que algumas pessoas acreditam possuir propriedades medicinais. Estima-se que a indústria de ejiao demande atualmente cerca de 4,8 milhões de peles de jumento por ano. Uma vez que não existe uma cadeia produtiva fora da China, a atividade é extrativista e resultou na drástica redução das populações. A gestação dos jumentos é de 12 meses, aumentando o risco de extinção se tais práticas não forem controladas. Neste cenário, os jumentos são recolhidos (comprados a preços baixos, roubados e recolhidos à beira das estradas) e são frequentemente transportados para longas distâncias, normalmente sem água, comida ou descanso. O comércio no Brasil apresenta riscos significativos de biossegurança, principalmente porque os exames raramente são realizados e, portanto, doenças infecciosas, como mormo e anemia infecciosa equina, permanecem sem detecção. Além disso, em situações de estresse crônico, o sistema imunológico é suprimido, aumentando o risco de biossegurança, principalmente porque os jumentos são portadores silenciosos de doenças. Raramente há rastreabilidade, e os animais de diferentes origens acabam sendo colocados em "fazendas fantasma", antes de serem entregues aos abatedouros. A estratégia oportunista de coletar animais, ou comprar por preços irrisórios, mantendo-os sem acesso a alimentação e assistência veterinária, é o que torna esse comércio lucrativo. Nossa experiência em bem-estar de jumentos e no comércio global de peles sugere que será extremamente desafiador e com custo proibitivo administrar um comércio dentro dos padrões exigidos para ser considerado humano, sustentável e seguro. Embora os jumentos sejam responsabilizados pelo envolvimento em acidentes rodoviários, não é uma solução ética manter este comércio como uma alternativa. Além disso, o papel ecológico dos jumentos nos ecossistemas nativos não foi elucidado, e alguns estudos indicam que eles podem até ter um efeito positivo. Independentemente do futuro que os jumentos terão, devemos garantir uma vida com o mínimo de dignidade aos animais sob nossa responsabilidade.(AU)

Donkeys (Equus asinus) face a global crisis. Their health, welfare, and even their local survival are compromised as the demand for their skins increases. Such demand for donkey skins aims to supply the ejiao industry. Ejiao is a traditional remedy made from the collagen of donkey skins. Some people believe it has medicinal properties. It is estimated that the ejiao industry currently requires approximately 4.8 million donkey skins per year. Although the future of the donkeys is still uncertain, we must guarantee a life free from suffering to the animals under our responsibility. The trade of donkey skins also undermines the cultural role of donkeys. Donkeys have developed an essential role in Brazil, especially in the Northeast region of the country, carrying on their backs construction materials, water, and food, and, as a consequence, helping people build cities in the deepest hinterland. The close relationship between people and donkeys affords donkeys a unique place in the local culture. This central importance has been recognized by Brazilian artists throughout history. We have many examples of songs, books, "cordeis" (typical Brazilian literature), poems, documentaries, movies, woodcuts, paintings, and sculptures, created to honor this important actor. Here we describe some examples of this human-donkey relationship, and its influence on our culture.(AU)

A preocupação ética também inclui o papel cultural dos jumentos. Os jumentos desenvolveram um papel essencial no Brasil, especialmente na Região Nordeste do país, carregando nas costas todo o tipo de material de construção, água e comida e, como consequência, ajudando o ser humano a construir as cidades no sertão. Devido à estreita relação com os seres humanos, os jumentos também estão participando da cultura. Essa importância central foi reconhecida por vários artistas brasileiros ao longo da história. Temos muitos exemplos de músicas, livros, "cordéis" (literatura típica brasileira), poemas, documentários, filmes, xilogravuras e esculturas feitos em homenagem a esse importante ator. Aqui descrevemos alguns exemplos dessa relação humano-jumento e sua influência em nossa cultura.(AU)

Unpredictable floor motions during transport disturbs animals' balance, requiring stepping to move the centre of gravity in the direction of body movement. When repeated regularly, this may be stressful, requiring involvement of the right brain hemisphere, hence we investigated the existence of behavioral laterality in sheep during prolonged floor motions. Six sheep were restrained in pairs on a programmable rocking platform, in which they were unable to turn around. They were exposed to three continuous rocking motion treatments (roll, pitch or both) in a regular or irregular pattern for 1 h periods in a changeover design. Right forelimb and left hindlimb diagonal stepping was more frequent in response to the motion treatment of irregular roll and pitch, which previous research has suggested to be the most stressful from heart rate measurements. An overall strategy to maintain balance appeared to be the use of the right hindlimb as a stabilizer, which was repositioned least often of all limbs until towards the end of the hour of experimental treatment. Of each tested pair, sheep restrained on the left side of the rocking floor stepped significantly often than its partner restrained on the right side, and we postulate the existence of visuomotor lateralization as left restrained sheep were unable to view their partner within the field of view of their left eye. We also investigated which side sheep lie down on, which if left lateralized could explain our observed bipedal diagonal control of sheep balance under stress. From the observation of 412 web-based images of sheep, there was an overall left-sided laterality to their lying, as has been observed in cattle. We conclude that stepping activity in sheep in response to a motion stressor is lateralized, providing evidence that floor motion experienced in transport may induce stress responses.
RESUMO
Motion sickness is a common response in humans and some species of farm livestock during transport, but research on the impact of motion has been primarily focused on the use of animal models for humans. During livestock transportation, animals seek to minimise uncontrolled movements to reduce energy consumption and maintain posture. Road and sea transport of livestock can produce motion sickness and stress responses. Clinical signs are the result of autonomous nervous system activation. Studies conducted on road transportation effects in domestic animals showed several motion sickness behaviours including vomiting and, in ruminants, a reduction in rumination. However, there is a lack of knowledge on the impact of sea transport motion. Despite the paucity of data on livestock, there is sufficient evidence to believe that motion might affect animal welfare when animals are transported by road or sea.

The transport of livestock by ship is growing in importance, but there are concerns about the welfare impact on the animals. Short sea journeys are usually completed in the vehicles that are used to transport the animals by road, and injury and stress can result. Long sea journeys require offloading of the animals into pens, where they are mixed and provided with feed, water and sometimes artificial ventilation. In addition, animals are often exposed to high stocking densities, elevated temperature and ammonia concentration, as well as noise and changes in photoperiod and light intensity. Mortality rate is the main measure of welfare used by the Australian live export industry for long distance shipments, and the rate is higher at sea compared to the same period of transport on land. Heat stress often challenges livestock when they are transported from cold to hot regions at high stocking densities with no diurnal temperature fluctuation. Sheep cope with heat stress better than cattle, but can still develop respiratory alkalosis if hyperventilation ensues. Bos taurus cattle cope less well with heat stress than Bos indicus breeds. High ammonia concentrations may accumulate on long voyages, causing mucosal irritation and pulmonary inflammation. Some sheep and goats do not adapt to the pellets provided after extensive grazing in Australia, resulting in inanition, often in combination with salmonellosis, which together are the main cause of high mortality rates. Long distance transport may also result in disease transmission to the recipient country and high standards of biosecurity are necessary. It is concluded that there are significant risks to the welfare of livestock caused by transporting them in ships, especially over long distances.
