Methodology

Literature review, questionnaires and interviews, on-farm welfare assessments and statistical analysis of all data.

Aims
  1. Research: understand the key requirements of donkey milk, its demand on a demographic basis and if methods to reduce bacteria are adopted.
  2. Research: understand European Regulation and local animal welfare legislation to determine how the donkey is categorised - domestic or agricultural animal.
  3. Investigation: gather data about the husbandry of donkey stallions, both as studs and those surplus to breeding. Collect information regarding their final destination (pet, work, meat production). As for male donkeys intended for meat production, farming methods and distances travelled to reach slaughter will be investigated.
  4. Investigation: donkey welfare assessment on dairy farms will be conducted through direct collection of animal-based indicators developed within the AWIN (Animal Welfare Indicators) project.

Communications: as a deliverable and extended report of principal results of analysis, raw databases, participation (or planning for participation) to an International Scientific Congress to disseminate results.

Results

1) Milk use results:

Of the eleven farms visited which were producing donkey milk for sale, all produced milk which was intended for human consumption. Eight farms also produced cosmetics and four additionally transformed milk into confectionery products. The main sales channel was direct to the consumer (N=11), other options were a small consortium (N=1) and a non-specialised shop (N=1).  The marketing channels were websites and social networks (N=8) and word of mouth (N=8).  None of the sampled farms sold milk to paediatric wards.  Consumers mostly bought fresh milk directly on farm more than once a week (N=5) or less frequently (N=6).  All the consumers, as reported by farmers, were children in the household, and it was interpreted from the questionnaire that they needed to drink milk for health reasons.  All the farms but one performed mechanical milking, the remaining one   did   manual   milking; machines   used   were   modified from a goat milkmaid. Nine farms milked once a day, the remaining one milked upon request. All the farmers adopted a method of cleaning and disinfection of the teats: damp cloth, disinfectant or pre-dipping.  Five farms performed pasteurization, four refrigerated the milk, one farm performed filtering and one farm froze the milk. All the farms but one periodically carried out milk analysis, with   eight   farms   searching   for   somatic   cells (22916,7±34851,5 SSC/ml) in addition to bacterial count (134166,7±229383,3 cfu/ml). All the farmers declared not to use any drugs on lactating donkeys. It remains to be investigated if and how lactating donkeys were treated when ill.

2) Legislation results:

According to European Council Directive 98/58 donkeys kept for milk/meat production should be considered as farm animals. Also within the council directive are non-species-specific guidelines on minimum standards for the protection of animals bred or kept for farming purposes. Within European Regulations 37/2010 and &Italian Dlgs 193/2006 is stated that a veterinarian must prescribe pharmacologically active substances and commend an appropriate withdrawal period. No specific information regarding drugs for dairy donkeys is reported. Italian guidelines “Codice per la Tutela e la Gestione degli Equidi” state essential criteria for proper management of equines and make suggestions about nutrition and water provision, stable management, training, identification documents, transport, euthanasia and education of farmers; none of which are specific for donkeys or dairy donkeys. Italian Regional D.D. 461 17/06/2013 & Circolare 17 05/10/2005 & ALLEGATO A Dgr 513 03/04/2012 generically suggest that donkeys should be kept in good welfare conditions, but with no specific indication about how to guarantee a good welfare state.

3) Husbandry results:

Twelve farms were visited between June and September 2015 by two assessors. The welfare assessment was conducted on a representative sample of animals, using the AWIN welfare assessment protocol for donkeys, comprising 22 animal-based indicators. A total of 257 donkeys (females = 131; pregnant females = 73 gelding = 1; stallions = 52) of different breeds, aged between one and 360 months (mean = 65.70 ± 61.92) were assessed. Data was collected using ODK application and analysed with IBM SPSS Statistic 23. The proportion of donkeys with different scores for each welfare indicator was calculated.

4) Welfare assessment results

On the average, the assessed donkeys had a good welfare status. Most of the donkeys (80.2%) showed a good nutritional status (BCS = 3); the others tended to be thin (12.8% with BCS = 2) rather than fat (6.2% with BCS = 4). The main issue highlighted was hoof care: 18.7% of the donkeys showed signs of neglect. All the donkeys could express normal behaviour and interact with conspecifics. Most of the donkeys showed positive reactions to human-animal relationship tests; 20.9% donkeys were not used to be restrained with a head-collar; thus, it was not possible to assess them.

Conclusions

Belonging to a given farm or production group influenced many of the welfare indicators. The absence of pasture affected the likelihood of having skin lesions, alopecia, low BCS scores and a less positive emotional state. Lack of routine veterinary visits (P < 0·001) and having neglected hooves (P < 0·001) affected the likelihood of being thin (BCS < 3). Belonging to specific production groups, lack of access to pasture and showing an avoidance reaction to an approaching human (AD) resulted in risk factors associated with a higher prevalence of signs of hoof neglect. The results support the idea that lack of knowledge of proper donkey care among owners was behind many welfare issues found.

To date, this was the first study investigating different aspects of donkey milk production.  Even though the sample of dairy donkey farms assessed was small, considerable differences were found in management and milk processing. These differences are likely due to the lack of uniform information available for the farmer.  The adoption of scientific based procedures in both management of donkeys and milk processing is suggested in order to improve both animal welfare and milk quality raising the consumer trust in this niche product. This led to the creation of the guidelines ‘Dairy donkeys: good practice principles for sustainable donkey milk production’; launched in December 2017. They include suggestions derived from scientific literature and/or reported by internationally recognised experts. The guidelines provide clear and helpful advice on good animal management practices for anyone interested in donkey milk production. They comprise the following chapters:

  • Responsibilities
  • Feed and water
  • Housing and management
  • Donkey health care
  • Humane killing
  • Appropriate behaviour
  • Milking procedures.

Methodology

Prospective clinical assessment, post mortem tissue collection for future trypanosome RNA isolation. Analysis for the presence of specific mutations found in T.b.evansi / T.b.equiperdum subspecies. Further development of histological grading system.

Aims
  • Is the neurological disease cerebral trypanosomiasis caused by a sexually transmitted subspecies of T. brucei, rather than by tsetse transmission?
  • Could the condition be controlled by effective breeding policies?
  • Can an effective protocol be developed for the treatment of equine cerebral trypanosomiasis?
Objectives

1. Improved knowledge of the subspecific aetiology, route of transmission and epidemiological spread of neurological equine trypanosomiasis. 2. Establishment of a specific laboratory standard technique for differentiation of sexually transmitted trypanosome species from tsetse or alternative vector spread species. This will be of international benefit in distinguishing route of transmission. The international IFAT in current usage does not distinguish dourine from either nagana or surra as there is cross reactivity. 3. Production of a histopathological grading system for equine cerebral trypanosomiasis. 4. Production and initial implementation of an improved control strategy for the prevention of cerebral trypanosomiasis in this region of Africa, with consequent welfare and economic benefits.

Methodology

Capturing interspecies interactions demanded a methodology that was flexible enough to include children and donkeys as equal participants. Many of the autistic children who took part in this research were non-verbal, therefore the methods utilised for exploring their inner lives and affective states were compatible with those often used to study non-human animals.  

What is lost with some quantitative research methods is the temporal sequence of events during relationship formation which was seen as critical in donkey assisted therapy (DAT) sessions. Capturing individual stories by using multispecies ethnography complemented the quantitative data and offered examples of the context and tangential variables surrounding interactions that would be impossible to control for in a quantitative repeated measures design.  

Aims
  1. To explore if The Donkey Sanctuary donkey assisted therapy program continued to be beneficial for both children and donkeys as the founder Elisabeth Svendsen had intended when she set it up in the mid 1970’s. 

  2. To focus on exploring the child and donkey relationship by viewing both as active participants (much of previous body of work focussed only on the human’s responses). 

  3. To rigorously explore the engagement between child and donkey, with a view to informing practice going forwards. 

Objectives
  1. To develop a Quality of Engagement tool 

  1. To investigate and answer the following questions: a) how does one member of a child-donkey dyad affect the other in equid assisted activities (EAA), and b) do participants act differently with members of their own species as opposed to the other?  

Results

The research confirmed that interspecies engagement can be measured equally for both species and the results can be used as an indicator for welfare and consent of non-verbal participants. It did not, however, show that such engagement reflected outcome benefits. ‘Benefits’ are subjective and dependent on how and of whom the question is asked. Other EAA research has indicated that there are positive ‘benefits’ from EAA, yet they have not included measures of engagement their participants actually experienced. Without a clear indication of engagement between partners, it is not possible to attribute these benefits solely to the EAA. The undefined yet very special ‘thing’ that is so attractive about donkeys and horses should be observed as a concrete variable, such as their emotional state and motivation to engage for the purpose of EAA research. 

The relationship between autistic children and donkeys relies on the uniqueness of each character on any given day. Autism is not a homogeneous description of a person, and whether it is considered a diversity or a diagnosis, it still translates to each person being unique. Both humans and donkeys are individual characters made up by their culture, family group norms, peer norms, genetic makeup, individual histories, and individual personalities. How they will relate to one another is very hard to predict and therefore requires constant monitoring for both welfare and consent. 

Autistic children and donkeys were shown to be a compatible coupling because some of their traits were similar and complemented their interactions. Both cohorts required a calm environment to be able to focus, smooth and fluid movements from others around them and as much time as they needed to process information. EAA is not a lifesaving medical intervention therefore it should only be considered as a practice for those children who show a willingness towards interactions with other species. Equally, some donkeys may find certain individuals or environments distressing and this should be monitored and respected.  

Conclusions

The findings of this research showed that both human and donkey partners were affected by the other and many of those interactions were considered positive, but not all. The donkey participants in this research significantly modified their behaviour to accommodate the children. Donkey behaviour was different when they were with other donkeys showing their awareness of the vulnerabilities of children in EAA sessions. Children were also affected by the other partner in the dyad. Some were generally more aversive towards donkeys than they were to other children which could be attributed to species communication differences however, some children were able to relax more when with donkeys than other children.  

The ethnographic stories highlighted the differences between human-donkey dyads and just how difficult it is to direct individuals towards meaningful relationships within a given environment or timeframe. This is the both the crux and the mystery of EAA. It is the understanding of who the other is and the resulting quality of engagement that dictates the interpersonal experiences within sessions.  

Equidae hindgut anaerobic fungi: a key unexplored taxa of central importance to dietary fibre degradation

Methodology

To characterise the core equine faecal microbiota, faecal samples were taken from 70 different equids including donkeys, horses, ponies, mules, hinnies and zebra.  The subjects were all aged between 4 and 26 years and were healthy with no known history of gut mediated disease. All animals were maintained on pasture or fed hay/haylage and in some cases received complimentary feeds in order to meet dietary requirements.  In order to capture as much variation as possible animals were sourced from different geographical locations. DNA was extracted from the faecal samples and used to quantify anaerobic fungi, bacteria, protozoa and archaea using quantitative PCR and Amplicon Barcoding Sequencing (MiSeq).

To determine whether differences existed between the faecal microbiota of domesticated equines when fed the same diet; ten ponies, ten donkeys and ten donkey hybrids were kept under similar conditions for a four week period, which consisted of a two week pre- sampling phase and a two week sampling phase. Animals were all housed similarly and fed  the same type of forage. Samples of the forage being fed were collected each day during the two week sampling phase and at the end of the study were pooled and chopped. Sub-samples were taken, weighed and dried to determine dry matter and then the dried samples were sent to an external laboratory for nutritional analysis by NIR. One complete faecal deposit was collected from each of the animals on the last day of the sampling phase. DNA was extracted from faecal subsamples and used to assess the quantity and community composition of anaerobic fungi, bacteria and archaea using QPCR and MiSeq based analysis. The effect of different seasonal diets was investigated across a two year period using four experimental periods lasting 25 days each. Each experimental period consisted of three phases; an adaptation phase (12 days), a recording phase (13 days) and a sampling phase (last 6 days of the recording phase). During the adaptation phase animals were accustomed to being fed a 2.5g high fibre carrier which was given twice daily. During the recording phase an n-alkane marker was administered via a dosed 2.5g high fibre carrier. In the sampling phase forage and faecal samples were collected. During the summer experimental periods animals were given free access to grazing and ad lib straw whereas during the winter experimental periods animals were co-housed and fed ad lib straw and limited haylage. Samples of the grass and/or forage fed during the last 6 days of the recording phase were pooled, chopped and subsampled and analysed for their nutritional content and alkane composition. A faecal sample from each animal was also collected daily during the recording phase.  Subsamples were taken to a) determine the dry matter, b) to create a pooled sample for alkane and nutrient analysis and c) to be used for DNA extraction and microbial analysis.

An in vitro study was also performed using horse gut contents collected from six segments of the hindgut (caecum, right ventral colon, left ventral colon, left dorsal colon, right dorsal colon and the rectum) in order to assess anaerobic fungal fermentation of forage along the hind gut. An antimicrobial treatment was used to enrich anaerobic fungi from each of the three sites. 

Aims

To identify any similarities or differences between the faecal microbiota of different equine species taking into account diet and management.

To determine the impact of anaerobic fungi taxonomy and physiology on dietary fibre degradation.

Objectives
  1. Characterisation of the core equine faecal microbiota across multiple equid (sub)species by determination of bacterial, archaeal and anaerobic fungal concentrations and composition
  1. Assessment of the taxonomy and physiology of anaerobic fungi present in a range of equid species with additional comparison against ruminant data
  1. Determination of whether the faecal microbiota of domesticated equine species and their derived hybrids differs when diet is controlled.
  1. Determination of whether seasonal changes in diet affect the faecal microbiota, and in particular anaerobic fungal concentrations of donkeys
  1. Investigation into the anaerobic fungal community composition along different parts of the hindgut and assessment of the impact of anaerobic fungi on forage fermentation
Results

Equine type was associated with differences in both faecal microbial concentrations and community composition. Donkeys were generally most distinct from the other equid species, with horse and zebra not being found to differ. Despite this, a common bacterial core of eight OTUs and 16 genus level groupings were found in all faecal samples and this bacterial core represented a much larger proportion of the equine faecal microbiota than previously reported. Anaerobic fungi were detected in all animals but donkeys had 6-fold higher faecal concentrations than horses and 8-fold higher than in zebra. No anaerobic  fungal taxon was found to be common to all equines. Caecomyces was predominant in donkeys and donkey hybrids and an uncultivated anaerobic fungal genus AL1 was predominant in horses/ponies and zebra. 

When diet was controlled though, faecal prokaryotic and anaerobic fungal community composition significantly differed between equine types but not prokaryotic alpha diversity, faecal microbial concentrations or faecal dry matter content. Donkeys, compared to ponies and donkey hybrids, had higher relative abundances of two bacterial genera that have known, or a potential role in plant fibre degradation and donkeys also had an increased number of anaerobic fungal OTUs and a higher relative abundance of the uncultivated anaerobic fungal genus SK3. 

Interestingly, when looking at the seasonal differences in diet, anaerobic fungal concentrations differed between both years for the summer diet but not for the winter diet. 

Results of the in vitro study showed that, independent of gut site, the enrichments resulted in an increased proportion of acetate (the major fermentation end product of anaerobic fungi) compared to the untreated controls. This suggests that the treatment was effective at enriching equine anaerobic fungi, and indicated that anaerobic fungi can make a significant contribution to hindgut fermentation of plant material. 

Conclusions

The results from this project showed that anaerobic fungi are i) a diverse and normal part of the hindgut microbiota of all equines, (ii) affected by equine type and (iii) diet, and (iv) are active along the equine hindgut. 

This study highlighted the potential value of anaerobic fungi in terms of improving fibre degradation in the equine hindgut. This baseline knowledge can be further developed to facilitate future novel approaches to enable equines to harness more energy from forages to be realised.  Within the equine industry this may ultimately translate into feed supplements that increase the activity and/or number of anaerobic fungi in the equine hindgut. Alternatively, anaerobic fungi may also be used as a direct feed microbial.  This would benefit equines with higher energy requirements by decreasing the need for energy dense feeds. Furthermore, in regions where only limited feed sources and poor quality forage are available, increasing forage degradation will also help animals meet their basic maintenance energy requirements. 

Overall this study has laid the foundations of a way to optimise fibre utilisation in equines which can beneficially impact the health and welfare of all domesticated equines and the societies and industries that rely on them.

Whilst differences were observed between equine types, a core faecal microbiota existed across all equines and comprised predominantly of bacteria. Differences, observed between donkeys and other equine types, largely related to a higher relative abundance and diversity of taxa with known, or speculated, roles in plant degradation. These findings were consistent with the previously reported increased fibre degradation in donkeys compared to ponies and donkey hybrids and suggest that the hindgut microbiota plays a role. 

The role, importance and impact of veterinary drug retail outlets (VDRO) on the welfare of equines and their owners in India

In spite of their official classification under “livestock”, and the significant role they play in the livelihoods of millions in the developing world, equines and those who depend upon them for their livelihoods tend to be ignored within the research agenda. It is also the case that other livestock are often valued over working equines due to their 'direct link to food and nutritional security'. Equine welfare in this case, with respect to veterinary treatment, might therefore suffer as a consequence of this placement of value. Couple this with the fact that the majority of donkey and mule owners in developing countries live in marginalised or poor communities and it becomes clear that the medicating practices of equine owners require further investigation to understand how they make decisions regarding the veterinary treatment of their animals, and who they source their medication and advice from when their animals require medications. This research will attempt to fill some of these gaps in knowledge.

Methodology

Fieldwork focussed largely on communities working in brick kilns but also incorporated some working in construction. A small proportion of the research aimed to capture any differences between sites where Donkey Sanctuary India (DSI) partners had provided veterinary interventions and advice and sites not visited by DSI. A mixed methods approach was identified as most appropriate in capturing the lived experience of donkey owners as well as members of the veterinary retail outlet workforce, and was undertaken through semi-structured interviews (enabling quantitative and qualitative data capture), focus groups, patient simulation method, knowledge assessment through the use of vignettes. Both donkey owners/users as well as a purposive sample of VDRO workforce members and veterinary service providers was recruited for participation. Equine welfare was measured using the Equid Assessment Research Scoping (EARS) tool. Videos were also taken of each equid/ group of equids for qualitative behavioural assessment. Fieldwork was carried out in February/ March due to their relative seasonal reliability in terms of weather, as well as corresponding with the early brick kiln season in the specified study location.

Aims

This project contributes to, what is currently, a limited existing body of knowledge regarding equine health service provision in India. It focused primarily on the role of veterinary drug retail outlets in urban areas such as Haldwani), peri-urban areas (such as Rewari and Firozabad), and rural areas (within Uttarakhand or Rajasthan).

The research aimed to understand:

  • User perception and experience of veterinary drug retail outlets in terms of affordability, availability, accessibility, acceptability, quality of service and sustainability.
  • The extent to which users depend on the services of veterinary drug retail outlets in the treatment of their animals and equines
  • The characteristics (outlet type, products stocked, drugs stocked, drug sources), capacities (training, education, skills), and drug prescribing practices of the retail outlet and its workforce
  • The impact of the above variables on donkey/mule welfare

Further to these aims, the project sought to identify constraints to equine owners with regards to equine welfare, as well as to examine the working constraints of the veterinary drug retail outlet workforce in the designated region of study.

Data collected regarding the above points was analysed alongside equine welfare data collected via the EARS tool in order to discover any potential correlation between equine welfare and retail outlet-related variables.

A small proportion of this study included comparison work between Donkey Sanctuary India sites and sites where there has been little to no intervention by an equine-related organisation.

Objectives

The purpose of this research project was to identify the role, importance, and impact of veterinary drug retail outlets (VDROs) on working equine welfare in India. The research gathered relevant data regarding health and wellbeing of donkeys in greatest need internationally, as well as aiding to understand associated biosecurity and environmental risks (such as cross contamination or antimicrobial resistance), and equine lifecycle and disease.

Conclusions

The study highlighted significant issues around the capacity of retail drug outlets particularly; a lack of knowledge, education and training in the dispensing of drugs to equids meant many equids received either the wrong treatment or incorrect dosage for presenting symptoms; when antimicrobials were offered this malpractice has considerable implications for antimicrobial resistance in equid populations. This is of particular concern when considering the highly mobile nature of working equids; frequently crossing borders whilst being translocated for migratory work and when being sold.
