Abstract

At present there are no published feeding guidelines specific to donkeys. Current recommendations are to feed 0.75 of horse energy needs on a body weight basis. However, it has been shown that donkeys have a greater digestive efficiency than horses and ponies and thus, feeding them as though they were small horses results in excess energy intake and, as a consequence they become obese. The formation of feeding guidelines begins with the estimation of the energy requirement for maintenance, as this is the value upon which nutrient requirements are related to. The aim of the study was to determine the maintenance digestible energy requirements of mature donkeys during each UK season. Twenty mature donkeys (10 male, 10 female) were selected for use in the study. The donkeys were fed a diet of hay and barley straw in quantities that were adjusted to maintain body weight. An equilibration period of minimum 16 days was followed by a five day total faecal collection; this was carried out for each season. Food and faecal samples were analysed for dry matter (DM), organic matter (OM), digestible energy (DE), crude protein (CP), neutral-detergent fibre (NDF) and acid-detergent fibre (ADF); nutrient and energy intakes were calculated. There was a significant seasonal effect on all intakes except NDF and ADF. DM and DE intakes showed significant increases in winter compared to summer, rising by 42 and 35%, respectively. Digestible crude protein (DCP) intakes increased during winter and spring but were significantly lower in autumn compared to all other seasons. A strong seasonal effect was exerted on all in vivo digestibilities although there was no effect of sex. OM, NDF and ADF intakes were affected by sex with male animals having higher intakes compared to female animals. Comparison of these results with NRC (1989) horse requirements showed a considerably reduced requirement by donkeys for energy and protein and thus it was concluded that feeding tables specific to horses are not suitable for calculating donkey requirements.

Abstract

Nutritional status, measured as body condition, has been used to assess welfare in working equines. Dental abnormalities have a substantial impact on the nutritional status of equines because they limit digestibility of foods and then nutrient utilisation. In Mexico, most of the working equines show body condition scores below 2.5 throughout the year and teeth problems may have a role in this. The purpose of this work was to investigate the prevalence of dental disorders in a population of working equines in Mexico. The study was run within with the work of the mobile clinics of DS-ILPH-UNAM programme. A total of 3,838 equines in 47 rural villages were assessed. Data were collected by surveys and by recording dental disorders in a complete oral examination. Species (donkey, horse or mule), sex (male or female), age and body condition score of every animal was recorded. The prevalence of animals with dental disorders and the frequency of each dental pathology in the affected animals were calculated. Body condition and age of affected animals were recorded. The average prevalence of serious dental disorder was low in all the cases (13%) and did not differ among species and sexes. The most frequent condition affecting incisor line of occlusion was ventral curvature. Enamel points, hooks, ramps, accentuated transverse ridges and steps were the most frequent abnormalities of cheek teeth rows. The average age of affected animals was 10.4±5.8 years, ranging from two to 40 years. Age did not differ among species or sexes. Mules showed higher average age, but the range was narrower than in other species. With regards to the body condition, more than 60% of the affected equines were in the lowest range (<2.5). These results are the first to describe the prevalence of serious dental abnormalities in working equines in Mexico and suggest the subject deserves further investigation. The data would allow strategies aimed at improving equine welfare via nutritional status.

Abstract

Retrospective analysis of the clinic database between 2003-2005 indicated that tetanus (27 cases), colic (134), rabies (7), strangles (17), hyena bite (429), dystocia (39), hernia (27) and car accidents are the major causes of direct mortality in donkeys of Central Ethiopia. The case fatality rates of donkeys affected by these diseases were: tetanus 22%, colic 27%, dystocia 15%, strangles 12%, hernia 11%, hyena bite 7% and rabies 100%, in clinical intervention sites of the Donkey Sanctuary. In the non-intervention areas the mortality rates are expected to be higher as there would be no treatment intervention. In this paper the two major causes of mortality: tetanus and colic are discussed. In the project in Ethiopia, treatments of advanced cases of tetanus following standard procedures have been successful. Of 27 cases treated 21 have been cured. The treatment has, however, been expensive, costing the project an average of 1400 Eth Birr per donkey (mature donkey costs 300-400 Eth Birr) and requiring a long period of hospitalisation. In an ideal situation, prophylactic immunisation is the best option. Economic realities however prohibit such an option from being feasible in countries like Ethiopia. An extension system and strategy that focus on the prevention of wounds using proper harnesses/saddles and institution of a sound hoof care programme is the option in mind. Colic characteristics are: gastric impaction 8%, obstruction of small intestines 7%, colonic impactions 19%, flatulent colic 23%, enterolithiasis/foreign bodies 24%, throboembolism due to strongylosis and undiagnosed cases 19%. Free access to mouldy or coarse feed, ingestion of polythene bags, fertiliser sacks and used fabrics of nylon clothes were the major causes. Common sites of lodgement for enteroliths were the proximal portion of the transverse colon, transverse and small colons. Enterolith/foreign body was often diagnosed in pregnant donkeys with colic. Few cases were relieved by surgery. A considerable number of the enteroliths were removed by manual traction. Veterinary intervention alone will do little to alleviate such problems. The use of school children to collect polyethylene bags and fertiliser sacks, improve farmers' awareness of the risk being posed by these materials and that of braided nylon ropes. Encouraging farmers to prevent donkeys from grazing at waste disposal sites is also another preventive measure that can be practised against colic. Extension and education programmes for owners should pay particular attention to these issues.

Abstract

This study examined normal donkey teeth using gross anatomical inspection, computed axial tomography (CAT), radiography, scanning electron microscopy (SEM) and, decalcified and undecalcified histology to determine their normal gross anatomy, histology and ultrastructure. CAT findings have shown donkey endodontic anatomy and the density (in Hounslow units) of donkey calcified dental tissues, i.e. enamel, dentine and cementum to be similar to values recorded in horses. Decalcified and undecalcified histology has identified donkey cheek teeth to have a similar histological appearance to that which has been described in the horse. SEM of donkey dental tissue has demonstrated minor differences to normal horse dental ultrastructure. Now that normal donkey dental anatomy has been clearly defined, pathological changes can be identified in diseased teeth and supporting structures and will allow a better understanding of the pathophysiology of common donkey dental disorders. Ultimately the results of this project will enable better dental care specifically developed for donkeys, promoting welfare in the donkey.

Abstract

Working equines in Mexico are distributed throughout the territory, but the management practices and the health and welfare conditions differ widely between regions depending on people's customs and specific climate conditions. The Eastern coast of México has an important equine population used for work in rural production systems. Something that owners and animal workers are concerned about is how the gastrointestinal parasite burden affects the equines nutritional status and health. This is because parasite reinfestations are most likely to occur in hot, humid climates. However, there are few reliable data to support this and the lack of information makes it difficult to design treating strategies and extension activities to ensure the health and welfare of equines in these areas. To address this, a trial was designed to determine the prevalence of animals infected with gastrointestinal nematodes, the parasite burdens and their effects on the nutritional status and haematological values of working equines from a tropical area of Mexico. One hundred and twelve equines were randomly selected in five different villages of the area. One sample of faeces and one sample of blood (in a tube containing EDTA) were obtained from every animal. Gastrointestinal parasite burden using the McMaster technique, proportions of nematodes species present through a coproculture, packed cell volume, total plasma proteins, red blood cell count and white blood cell count, were measured. The nutritional status was assessed using body condition score. Data was analysed using descriptive statistics. All calculations were done per species (horses, donkeys and mules) and community (1, 2, 3, 4, and 5). Prevalence of infected equines was higher than 90%. The most common nematode species was Strongylus vulgaris. The parasite burden was low to moderate in horses and donkeys, higher in mules; however, it did not affect the body condition, nor the haematological values (P>0.05). Results suggest that in spite of the high prevalence and parasite burdens, equines involved in this trial are not being seriously affected, as shown by the body condition and haematological parameters.

Abstract

The Donkey Sanctuary in Ethiopia launched an empathy education programme at 7 primary schools in 2005, to nurture school children's empathy with working animals. The objective of the programme was to enhance the ability of schoolchildren to build smooth relationships and positive attitudes towards animals, resulting in the creation of responsible citizens who are compassionate, kind, and love and have empathy with all animals. To show empathy is to identify with another's feelings. It is to put yourself emotionally in the place of another.

Abstract

A small survey of working donkeys in Mexico illustrated a high prevalence of dental disease (62%). However, only 18% of cases were severe enough to have an apparent impact on the a donkey's welfare and required dental treatment. Many donkeys manage well with some degree of dental disease and owner education about agerelated dental disease and the need for supplemental feeding will alleviate some of the welfare implications of dental disease, particularly where resources for dental treatment are limited.
