The Animal Welfare Act states that all animals are entitled to:
Freedom from hunger and thirst: by providing enough fresh water and the right type and amount of food to keep them fit.
Freedom from discomfort: by making sure that animals have the right type of environment, including shelter and somewhere comfortable to rest.
Freedom from pain, injury and disease: by preventing them from getting ill or injured and by making sure animals are diagnosed and treated rapidly if they do.
Freedom from fear and distress: by making sure their conditions and treatment avoid mental suffering.
Freedom to behave normally: by making sure animals have enough space, proper facilities and the company of other animals of their own kind.
Horses are social, nomadic animals that prefer to live and move in groups over large open areas so they can flee from danger. Horses naturally partake in mutual grooming as a means of bonding and to develop a herd hierarchy (pecking order). Unfortunately it is almost impossible to provide this type of environment for the domesticated horse and it is easy to place human needs and preferences before the needs of a horse.
Freedom from hunger and thirst
Horses have evolved as trickle feeders, designed to be chewing/occupied by feed for a large portion of their day. Their digestive systems are primarily designed to digest fibre and, therefore, forage (hay/haylage/grass) should represent the majority of their diet.
Wild horses spend about 60% of their time eating. This compares to stabled competition horses kept in individual stables and fed rationed feed where only 15% of their time is spent eating. Although these horses usually receive good nutrition, their eating is done over 4-5 hours; a third of the time spent by wild horses who are free to graze at will (16-18 hours per day).
Ideally domesticated horses should have free access to fibre to allow them to eat for at least 16 hours per day and clean drinking water.
Freedom from discomfort
Horses evolved as a social species living in open plains where running away was their primary method of escape from predators. Today, horses still possess an inherent aversion to isolation and confinement. Research has shown that horses with free access to both pasture and to box stalls with bedding, hay and water, prefer pasture even during poor weather as long as some grass is available.
While horses do need some protection from the elements - shelter, trees, barn – they do not require warm housing and have been shown to be able to comfortably tolerate low temperatures. Horses naturally insulate themselves with their winter coats; however, horses with clipped coats may need rugs to maintain a comfortable body temperature. Anything that a horse wears, be it a rug, headcollar, bridle or saddle, needs to fit correctly and be cleaned regularly.
Horses that are in work should only be asked to do what they are capable of and what they enjoy.
Freedom from pain, injury and disease
It is important to make sure all reasonable steps are taken to prevent ill-health and to seek prompt veterinary care in the event of illness or injury.
A preventative health care plan should be implemented which should include worming and vaccinations. Your vet will be able to discuss an appropriate plan for your horse. To help prevent injuries, ensure that stabling and fencing is regularly inspected and any problems are repaired.
Freedom from distress and fear
Horses evolved as a social species living in open plains where running away was their primary method of escape from predation. Movement and grazing will naturally dominate the majority of a horse’s time. Therefore, confining horses to individual stables or paddocks may be insufficient to meet their social and mental needs. Distress may result from lack of social interaction and space.
Freedom to express natural behaviour
Chronic frustration from isolation, lack of social contact, lack of environmental enrichment and/or lack of stimulation can result in abnormal or stereotypic behaviours (‘stereotypies’). Abnormal behaviours include pacing, licking, eating or chewing of non-food objects. Stereotypies are repetitive behaviours horses use to cope with the abundance of time that would otherwise be spent grazing and socializing. Examples of stereotypies include crib biting, weaving, wind sucking, head tossing and head nodding. Unfortunately some stereotypies become learned behaviours that cannot be resolved, even after the horse has been removed from the environment that initially triggered the behaviour (e.g. wind sucking).
Try and make the environment as natural as possible for your horse by ensuring they have at least one friend to interact with and a field to run around in for at least some of the day. Ideally at least 4 hours per day should be spent out of the stable, while able to move in all gaits.
