To date, it has become common knowledge to never exercise your horse on an empty stomach. Yet, to the best of my knowledge, little has been published about transporting on an empty stomach.
Considering a horse's natural instincts, transport is inherently stressful. Add to that lack of forage - or lack of access to forage if your hay ends up on the floor - and you've combined two common causes of gastric ulcers. Very alarming - considering ulcers can occur in as little as 24 hours.
Thankfully, you can be proactive by providing forage (hay, pasture or soaked hay pellets) 1) prior to departing, 2) during transport and 3) once you arrive at your destination. Read on to learn why forage (not grain or sweet feed) is crucial for all three scenarios.
Important Exception - if you’ve been instructed to withhold feed due to a medical condition, by all means do so!
Why Transport is Stressful
Transport impairs every natural survival instinct your horse has: sight, sound, smell and flight in order to detect and flee from perceived danger. Impairment of these instincts causes stress. Horses are stoic by nature and don’t always exhibit outward signs of stress.
Suffice it to say that if your horse is transported, he or she is stressed internally to some degree. Some may exhibit stress outwardly by refusing to load, pawing once in the trailer, whinnying or kicking the walls. Horses rarely do anything that doesn’t have a purpose. They don’t have the mental capacity to ponder and carry out acts intended to be annoying. It is our responsibility as their guardians to reduce their stress level mentally and physically to the best of our ability.
"Transport is an extended isometric exercise for your horse - requiring your equine friend to constantly balance by engaging the abdominal muscles. Contraction of the abdominal muscles forces acidic gastric juices up into the non-glandular (upper) region of the equine stomach."
Why Feeding Forage Prior to Departure is Beneficial
Horses, donkeys and mules produce gastric acid continuously in preparation for constant uptake (think natural grazing behavior). Chewing and swallowing activate saliva production (an alkaline substance), which buffers gastric acid by increasing the pH of the stomach.
By the time you load into the trailer, your horse's stomach pH will be lowered. Loading with an empty stomach allows accumulated gastric acid (unbuffered due to lack of saliva from chewing) to slosh and bathe its lining. The fiber that forage provides creates a mat of sorts, which prevents acid from splashing in the stomach.
Why Forage During Transport is Optimum
Transport is an extended isometric exercise for your horse - requiring your equine friend to constantly balance by engaging the abdominal muscles. Contraction of the abdominal muscles forces acidic gastric juices up into the non-glandular (upper) region of the equine stomach.
Chewing on forage produces saliva, which buffers the gastric acid, and relaxes the jaw. Tension in the jaw can radiate throughout the body. Mental and physical experiences are synonymous in that each has an influence on the other and both can induce ulcers.
The act of foraging during transport can also reduce mental stress by distracting the individual from focusing on the impairment of their natural instincts and redirecting their attention to food.
Whether caused by isometric balancing or taking bumps in the road, splashing gastric acids can induce ulcer formation or exacerbate existing ulcers to the extent they create an ulcer deep enough to cause bleeding or even burn completely through the tissue. Splashing of gastric acid on ulcers would feel similar to hydrochloric acid being splashed on your face.
Why Forage Consumption is Beneficial After Unloading
The equine stomach can empty in 20 minutes to 2 hours - depending on the type of feed and rate of consumption or when it becomes two-thirds full.
Stress persists upon arrival because your horse is in an unfamiliar setting with a heightened sense of survival instincts engaged. Whether tied outside your trailer, placed in a corral or stall in a strange environment or put into exercise immediately - your horse is experiencing many stressors.
The continuation of chewing and swallowing helps to:
How Slow-Fed Forage Benefits Horses During Travel
Most horses don't drink enough during transport. Offering loose hay - which horses can consume too quickly - results in large amounts of dry matter lacking sufficient saliva to forage ratio - combined with large particle sizes from not properly masticating indigestible fiber. Slow feeders can help address these issues by:
Helpful Tips to Reduce Stress While Traveling
Monitor Your Horse Trailer Interior Temperature
Temperatures inside horse trailers should be a concern and monitored at all times. Install a temperature monitor with a base station - the same type used in homes to monitor the outside temperature without going outside. This is an inexpensive investment for your peace of mind and your beloved companion’s comfort.
Hang the sensor in a mesh bag for good air flow or mount it about halfway up the side of the wall in the trailer (as far away as possible from a warm body).
Livestock can generate quite a bit of body heat, even in cold weather. Conversely, in warmer weather it can alert you if temperatures rise to a cause of concern. This allows you to open and close air vents and windows to achieve optimum comfort with confidence for your precious cargo.
