The other 23 hours
and The other 23 hours What does your horse do when you are not riding? How is he or she housed, inside or outside? Individually or in a group? Is your horse’s risk of injury greater from standing in a stall than living outside with others? Lisa Ashton, Director of EquiSci, looks at how our management choices enrich our horses and affect their welfare. Reporting from the 9th International Society for Equitation Science (ISES) conference in Delaware, USA, where plenary speaker Professor Jan Ladewig, a Fellow of the International Society for Equitation Science, focused delegates’ attention on the time horses spend away from the training arena. Quality time Equitation science is not just about studying the welfare of horses during training. Having healthy, safe and obedient riding or driving horses means considering and managing the quality of all the hours of their day and night. If your horse stands in a yard or stable most, if not all, of the day while you are not riding or training, he may show play behaviours when you turn him out and become difficult to handle. Similarly, if you keep your horse in a non-stimulating environment, they are much more likely to be frightened when you ride them or turn them out in a stimulating area, than if they spend most of their time in a stimulating environment. “If we expect horses to perform, either at a high competitive level or just during leisure riding, and if we expect them to be safe and easy to handle and ride, we must consider the quality of all those hours of the day when they are left by themselves,” remarked Professor Ladewig. So, is it possible to enrich our horses’ existence during the other 23 hours of the day?

Photo by Elke Hartmann, courtesy of ISES Although we are all taught that horses are highly social animals that evolved to wander and graze over vast open spaces, the domestic environment is often one of confinement, isolation and intermittent meals, all of which go against their psychological and physiological nature. A modern problem The unfortunate truth, however, is that the effects of ridden exercise followed by the reduced locomotion of 23 hours of confinement in a small stable or yard, are not fully understood. A training arena or an automated horsewalking machine are poor substitutes to the freedom of moving around in large pastures. An important question, therefore, is how much are riding horses actually moving? While one study recorded that on average, riding sessions lasted 41 minutes, 6 days a week, Professor Ladewig urged delegates to conduct many more studies to help establish a much clearer picture of how sport and leisure horses are managed worldwide. “ If we are really concerned about the welfare of riding horses, getting away from individual housing and over to group housing is essential. shutterstock.com continues next page... It is not enough for horses to see, hear and smell other horses. Horses need full, unlimited, physical body contact to be satisfied, as well as the freedom to move, forage and graze for long periods. Image source: http://homepage.usask.ca The domestic reality In a study of over 2,000 Swiss horses, almost 84% were individually housed, of which just 36% received daily turnout. In another study of 445 Danish horses at 12 riding schools, 25% were turned out less than three times a week. Of those regularly turned out, over 50% were outside for less than five hours. Fast Fact Out of 254 animal-related human deaths in Australia since the year 2000, horse-related activities accounted for 77 deaths compared to 16 shark-related deaths, 14 snake-related deaths and 9 crocodile-related deaths! www.horsesandpeople.com.au • HORSES and PEOPLE • Page 37 and “ We know horses evolved to move around at a slow walk while grazing for twelve or more hours a day. It cannot be good for them to stand still so much. A recent study compared the locomotion behaviour patterns of domestic horses at pasture with feral horses, highlighting just how wrong today’s predominate housing systems are, even for horses that live in fenced pastures. Feral horses travelled 10 kilometres more than horses at pasture. Interestingly, the behaviour repertoires of domestic horses were the same as those displayed by the feral horses, the only difference being the intensity of the behaviours. Is it any wonder horses, like humans, are suffering more from obesity? “Too many horses move around too little,” remarked Professor Ladewig. A strong bond Studies have also shown that it is not enough for horses to see, hear and smell other horses, and that horses need full, unlimited, physical body contact to be satisfied. Horses need physical contact for grooming each other, playing, or just having a buddy nearby while they are grazing or resting. For horses, allo-grooming (the mutual scratching with their teeth) is not just about having their backs scratched. Allogrooming is known to have a calming effect, possibly strengthening the bond between two individuals. Professor Ladewig asked why we don’t see it more often. Is it because today many horses wear rugs? Fast Fact shutterstock.com Comparison in locomotion of feral vs. riding horses: • • Feral horses - 17.9kms per day Riding horses - 7.5kms per day (Hampson et al., 2010) Page 38 • HORSES and PEOPLE • Phone: 07 5467 9796 • admin@horsesandpeople.com.au and Kerri Afford Photography SCIENCE CORNER This makes sense since the preferred grooming sites are around the withers, exactly the area that is covered by rugs and blankets. “We need some systematic observations of horse grooming with and without blankets,” urged Professor Ladewig. Time saving and convenience, but at what cost? However, it is not just keeping horses warm and dry that drives owners to keep their horses covered. “Many horse owners put on blankets not so much to protect their horse from the elements, but so they don’t get dirty and they don’t have to spend so much time cleaning!” said Professor Ladewig, as he pressed delegates to research the effects rugs have on grooming, rolling and other natural behaviours. “ shutterstock.com We do not even know why horses roll. Is it to scratch bites from insects? Get rid of loose hair? Or roll when wet from sweat or rain? We all have our theories, but they are yet to be tested. A Japanese study showed horses prefer to roll in dirt rather than sand and straw. But, if the dirt is wet and muddy...! Allo-grooming is not just about back scratching, it is known to have a calming effect, possibly strengthening the bond between two individuals.

It is not known how this is impacting their foraging behaviour and welfare.” “Only limited research has been done that investigated forage variety to support adaptive behaviour in horses (behaviour that helps the animal successfully adapt to its situation). Forage enrichment has been primarily studied in stabled horses, and this allows for more research in those managed on pastured paddocks. In addition, little work has been done to investigate the effect of forage variety on food intake, and the time budget of domesticated horses.” “My PhD project is focussing on the preferences of a varied diet (multiple choice and novel foods), and how this is affected by the nutritional and physiological status of horses,” says Mariette. The project, which is being conducted at the University of New England, New South Wales, includes a series of investigations to specifically address the following objectives: • A literature study will focus on adaptive foraging behaviour, biological bases of varied diet and post-ingestive feedback mechanisms, as well as diet selection and preferences in horses. It will highlight forage enrichment, as an aid to promote adaptive behaviour and address welfare concerns in domesticated horses. •STRESS •ITCH •NON TOXIC FREE •CHEMICAL Keeps your horses, ponies and foals... Happily Grazing • An industry survey will identify current management practices and foraging behaviour of pastured horses in Australia. Browsing behaviour has been predominantly recorded in free-roaming horse populations and the results of this survey will provide more insight into foraging and browsing behaviour in domestic horses (focussing on Australian vegetation). • A preliminary animal study will look at how energy intake levels influence selection of familiar versus novel forages. The aim being to review if the nutritional and physiological conditions of the animal will reflect their motivation to ingest novel forages. “The preliminary results,” explains Mariette, “highlight that food variety and its effect on diet selection is rather complex, and that learning plays an important role in foraging habits. The future direction of this PhD project could lead to investigating cognitive experiences or physiological (post-ingestive feedback) mechanisms.” Page 40 • HORSES and PEOPLE • Phone: 07 5467 9796 • admin@horsesandpeople.com.au shutterstock.com Being socially successful and SCIENCE CORNER We know horse’s are sociable and we also know horses need to be with other horses. Despite this fact, and as Professor Ladewig explained, many aspects of living together peacefully must be learned. “Learning about social communication occurs during the process known as socialisation, but how it actually comes about we know surprisingly little. What conditions stimulate the best results?” asked Professor Ladewig. One thing we do know is you need to start early. Raising young horses in homogenous peer groups often separated by age and sex, as practiced in most large breeding stud farms, does not stimulate the kind of socialisation that is needed for horses to easily adapt to a loose group housing system. Playing is learning An important part of socialisation is learning to deal with unfriendly and competitive situations. Whether it is play or serious aggression, Professor Ladewig explained a lot of learning happens in these interactions. s A video of two stallions was played during the plenary, with Professor Ladewig quizzing delegates: “Were they playing or fighting?” Maybe they started by playing and it turned into fighting or it was the other way around. Either way, both horses were learning. Learning not to get kicked by the opponent, and learning to deal with the competitive aspect. “ Horses of all ages (and especially young ones), should be exposed to competition and conflict situations so they can learn to solve problems in a non-aggressive way. continues next page... Socialisation is a learned process. Foals and young horses must be kept in mixed groups to learn all aspects of social communication. shutterstock.com “ www.horsesandpeople.com.au • HORSES and PEOPLE • Page 41 and Facing up to the challenge Problems with individual housing: • • • • • No possibility for social contact No possibility for grooming Poor air quality Un-physiological patterns of locomotion Un-physiological eating pattern Alternatives to individual housing: • • • • Loose housing Group housing Access to the outside (the larger the group the bigger the area required). Environmental enrichment: Foraging enrichment Dry soil for rolling Trees, branches, or wood to chew Loose and group housing requires horse owners to have a better understanding of horse behaviour and knowledge of each individual horse. We Want YOU! Have you embraced a group housing philosophy for your horses, whether it is outdoors 24/7 or part-time indoors and outdoors? Horses and People want to hear from you and your experiences in moving horses away from stables and individual paddocks to creating groups - whether it worked or it didn’t! Please email the editor@horsesandpeople.com.au Notably, whilst the stallions were ‘socialising’, curiosity was stimulated in the nearby young horses. Professor Ladewig clarified, even though we don’t know what type of learning is happening all of the time, we should focus horse owners on how to enrich their horse’s environment, and how to encourage learning to resolve conflict in a non-aggressive way. Reduced aggression Studies on pigs, egg-laying hens and cattle have shown that, contrary to expectation, keeping animals in large groups reduces aggression between group members. In a recent study that was also presented at this conference, a Dutch team of equitation scientists assessed the welfare effects of increasing roughage-feeding frequency from 3 to 6 times a day amongst 47 group-housed riding school horses. A large automatic feeding system moved in between the horses and distributed roughage over large feeding troughs. The bites and total aggression frequency before feeding time decreased significantly, compared with feeding three times a day. Interestingly, horses spent more time resting and less time feeding, whilst each horse’s body condition score remained the same. This new automatic feeding system made it possible to increase roughage frequency in group-housed horses, providing horses with more control over their environment. Stress and controllability If you have control over your situation, you are much more resistant to stressors. Professor Ladewig explained a very important aspect of group housing - horses deciding for themselves. Animals which have a much better chance to decide for themselves have much more controllability. “ Image courtesy of HIT Hinrichs Innovation & Technik GmbH We need more studies to show the effect rugs have on behaviours like rolling and allo-grooming. Page 42 • HORSES and PEOPLE • Phone: 07 5467 9796 • admin@horsesandpeople.com.au Solving problems Equitation science needs to investigate and identify the best environments for horses. Maybe we need to teach horses to eat peacefully together? Or gradually train them to be close together for short periods in small enclosures, just as we progressively train them to be separated. “One thing is clear - we need more studies,” said Professor Ladewig. “Keeping your horse in a barren paddock or in a paddock with nothing but grass is just not good enough. Horses need environmental enrichment - social contact, trees to stand under, bushes to hide behind and places to roll, besides food.” Horse-centred housing Understanding the effects of group housing is a challenge for equitation science. Some of the questions that deserve evidence-based answers are: • • • What is the optimal group composition? What about the costs of building a group housing system, compared to building and running a conventional system? What are the challenges facing horse owners? and Professor Ladewig’s thought-provoking plenary got me questioning why horse owners would measure their love by the number of layers and grams of rug filling. Have we forgotten horses know how to be horses? What is fuelling such unnatural husbandry practices? In the UK, as in Australia, we go as far as promoting and celebrating establishments who offer isolated stabling and individual turnout for our animals. Are we one step away from fitting radiators in stables? Amidst the deluge of ‘armchair experts’ that stalk internet forums, it seems difficult to access evidence and welfarebased knowledge. Can the click of a button result in horses experiencing less than optimal practices? And should pony clubs, riding clubs and federations be placing the spotlight on evidence-based education? The International Society for Equitation Science has launched a new initiative to provide owners with an online hub of easy-to-access educational and evidence-based resources. Just like nutrition and training, environmental enrichment should be an essential part of responsible horse management. As Professor Ladewig so frankly put it: “Equitation science is not just about sitting on the back of the horse.” shutterstock.com It seems success of a horse-centred housing system demands more of us, the horses’ caretakers. Professor Ladewig explained group housing demands better knowledge of horse behaviour and knowledge of each individual horse. As Professor Ladewig remarked: “Changing to group housing may solve some of the problems we have with horses, but it will probably result in other problems arising.” “ Keeping your horse in a barren paddock or in a paddock with nothing but grass is also not good enough. Horses need environmental enrichment. and With the prevalence of stomach ulcers in horses increasing, Professor Ladewig questioned how much is due to stress and housing: “We need further studies to tell us what current housing systems are doing to our horses”.
