Equine Stall Confinement Tips

Some horses spend a lot of time in a stall or small paddock. This can be because of a property’s space constraints, due to training schedules, or because of illness or injury.

Owners need to understand how stall confinement affects a horse’s physical and mental health. They also need to take action to mitigate the negatives of living in a stall.

Stall Environment

Indoor living poses a challenge to a horse’s respiratory health. If you’ve ever walked into a barn and been hit by ammonia fumes, you know what we’re talking about.

A horse living in a stall environment experiences effects from microbes and from particulates dispersed from feed, bedding, and diesel exhaust from vehicles in the aisleway.

Such airborne contaminants can lead to inflammatory airway disease (IAD), currently referred to as equine asthma.

Fecal matter, hay, and straw can contain endotoxins, which is a component of the bacterial cell wall of Gram-negative bacteria. Endotoxins are liberated as these bacteria die. Endotoxins adhere to airborne particles that can be inhaled.

Neither horse nor human does well when breathing in this potent substance; the airways react to this foreign protein (referred to as an antigen) by inducing an aggressive inflammatory response. Dust exposure—often containing endotoxin—can cause inflammation, mucus production, and breathing difficulty, all of which impair performance.

Soaking hay helps minimize dust and respiratory irritants. However, bacteria grow exponentially in moist materials. That makes wet hay a rich source of endotoxin. Feed only as much wet hay as can be consumed quickly.

Ventilation

Improved air quality in a stall depends on effective ventilation with ample air exchanges per minute. You might think that using a fan would help. Using a fan does not necessarily mean air exchanges, it just means you are moving bad air around. If you use a fan, you need a source of fresh air and a place like a window for the air to escape.

Curtail barn activities that increase dust particle concentrations in the air. Using a leaf blower to “blow” the barn aisle raises a tremendous amount of dust and particulates into the air. Refrain from that and other activities that raise dust when you have stalled horses.

Unfortunately, pasturing a horse outside doesn’t necessarily eliminate exposure to endotoxins. Wind currents and stamping horse feet stir up manure and dust, especially when horses congregate in one area. Therefore, even pastured horses can be exposed to endotoxins.

Minimize Respiratory Irritants

Here are some strategies to reduce dust and minimize respiratory irritants in a barn.

Feed quality, low-dust hay and use quality, low-dust bedding.
Clean stalls and paddocks once or twice daily to remove manure and urine-soaked bedding or dirt.
Wait until horses vacate the barn before mucking, raking, sweeping, and using a leaf blower in aisles.
Use fans only in areas where they don’t whip up barn or stall dust.
Good ventilation throughout the barn is paramount to respiratory health. Consult with expert barn builders or an extension specialist for design ideas.
Store hay in an area separate from the barn rather than using a loft over the stalls, arena, or barn area.

Stall Confinement and Colic

A stalled horse is often subject to specific feeding programs (twice daily, for example). This tends to increase the potential for colic problems as compared to horses living in a pasture and regulate their own feeding patterns. Horses that experience recently imposed stall confinement have 54% more cases of impaction colic than those living in more open areas.

It is also reported that 62% of colon impactions occur within two weeks of significant management changes, such as stall confinement or transport. It is the “change” that makes the difference, especially with concurrent changes in feed and housing that pose greater risks of adverse effects on intestinal health.

That said, a horse accustomed to stall confinement and consistent feeding is not as badly influenced by additional stall time once acclimated to this routine.

Dietary Management

Dietary modifications are important when managing confined horses. Try to minimize changes in feed type, volume, and feeding frequency. Always ensure ample water availability. Make sure to note that your horses are drinking! Tip: If you clean stalls twice a day, replenish water twice a day by discarding the old water and filling the bucket with fresh water.

Lack of exercise leads to weight gain. Therefore, reduce feed quantity for stalled horses, especially of concentrated feeds.

Feed less calorie-rich hay to horses prone to gastric ulcers so they can nibble hay throughout the day without becoming obese. Equine gastric ulcer syndrome also develops due to stress, so good management strategies rely on efforts to minimize overall stress.

Exercise yields multiple benefits to intestinal health by increasing metabolism and improving intestinal motility. Even light physical activity, like walking, stimulates GI motility. Fiber digestibility increases by 20% in horses that exercise.

Additionally, there is greater retention of the fluid part of the diet and shortened retention of the more formed, particulate part of the feed. This helps to deter impaction colic.

While dietary changes challenge equine digestion, decreases in activity due to restricted exercise also can create digestive problems leading to colic. Careful monitoring of appetite, manure, and urine output is important.

Effects on Performance

Fitness is proven to improve in horses that are given pasture and exercise compared to those that are confined. Pastured horses demonstrate lower heart rates during exercise, faster heart rate recovery, lower lactate concentrations, and they develop increased bone density. These findings are significantly different from stalled horses, regardless of their exercise level.

In one study, GPS units that monitored movement over a 24-hour period showed that horses pastured full-time tend to travel an average of 6.7 miles, which is twice the distance of those provided only paddock turnout at night.

Stall-confined horses, with or without exercise, travel only on-quarter to one-half as far as those in a pasture. Being more sedentary impacts intestinal health, muscle tone, joint lubrication, and cardiovascular fitness.

Confinement for an Injury

Stall rest is sometimes necessary for certain situations, such as for a musculoskeletal injury or a serious health problem. A short period of confinement (weeks) has little influence on joint and musculoskeletal tissue health and maintenance. However, anxious horses might move around more in a stall than in paddock confinement. Therefore, ‘rest’ needs to be tailored for each individual to be effective.

A horse owner can help with the physical therapy of an injured, stall-confined horse by performing passive flexion and range-of-motion exercise and stretches guided by consultation with their veterinarian.

Behavioral Effects

A confined horse is often denied the opportunity for normal social interaction and grazing. How much exercise a stalled horse needs each day depends on many factors, not just exercise. Absolute time out of the stall is not the only factor. What a horse is able to do in the time outside the stable is equally, if not more, important.

Horses are social animals used to moving large distances when enough space is provided. Behavioral problems might develop when a horse is isolated from others, especially if confined.

The lack of activity in a stall often results in overzealous activity when a horse is given the opportunity to exercise. Controlled exercise is important to ease a confined horse into more freedom.

Frustration in being sedentary for prolonged periods might cause a horse to channel that inactivity into problematic behaviors such as weaving and cribbing. With time, restrictions on movement, social interaction, and grazing can also cause a horse to be more likely to misbehave during handling, trailer loading, and riding activities. Such outbursts can impact horse and rider safety.

A stall-sized run with an inside stall provides clean air and a place to look around at the world. Whenever possible, give horses as much outside time as reasonable for mental and physical health. Stall-sized panel enclosures can form outdoor confinement areas that allow a horse access to fresh air along with physical and visible proximity to other horses. Grazing time is achieved by setting up the panel enclosure on grass and moving it at regular intervals to new grassy areas. It helps to give a confined horse some method of engaging his mind.

Stall Toys

Stall toys might help relieve boredom. Homemade toys are useful provided they are rounded with smooth edges and don’t contain small parts that could be swallowed.

A useful toy is crafted by placing hay cubes, apple pieces, and carrot pieces into a plastic gallon jug that is hung from the rafters. Another distraction from boredom is a food popsicle. You can add water (or juice) and cut-up fruits or veggies into a plastic container and freeze. Then, remove the plastic and put the “food-sicle” into your horse’s feeder. He’ll amuse himself by licking and gnawing at it to get at the treats while the ice melts.

There are also commercial stall toys that hold treats and can be rolled around by the horse, with treats falling out occasionally. An alternative is a Jolly Ball has a handle that allows a horse to amuse himself by tossing around and kicking the ball.

Final Words

Every horse tolerates stall confinement differently. Horses thrive best when given space to move, socialize, and play, even for just part of the day. Attention to these many details helps a horse’s body and mind withstand the challenges posed by spending significant time in a stall.
