In recent years, track systems, also commonly referred to as โ€˜Paddock Paradiseโ€™, have been popping up on more and more horse properties. These systems utilize a looping track or path, often around the perimeter of a field or property, instead of a traditional rectangular or square open paddock. Using 6โ€™ to 20โ€™ alleys, often with multiple feeding stations placed along the path, track systems are intentionally designed to keep horses moving and allow them to explore and interact with their surroundings in different ways.

But how do these setups actually stack up against the more familiar and traditional paddock system? Letโ€™s explore what each setup brings to the tableโ€”and what the evidence and experience are starting to tell us. ๐Ÿ‘‡

โš–๏ธ ๐–๐ž๐ข๐ ๐ก๐ญ ๐Œ๐š๐ง๐š๐ ๐ž๐ฆ๐ž๐ง๐ญ
Horses on a track system lost an average of 23.5 lbs (10.67 kg) between July and late September, while those in a traditional paddock gained an average of 15 lbs (6.8 kg). This suggests that the increased movement encouraged by the track design may help with managing body conditionโ€”an important consideration for good health, especially for horses with metabolic comditions.
๐Ÿ“šCameron et al., 2025

๐Ÿง  ๐๐ž๐ก๐š๐ฏ๐ข๐จ๐ซ
Horses on a track moved more, traveled further, and engaged in fewer overt agonistic behaviors when compared to a horses on a strip grazing system
๐Ÿ“š Kirton et al., 2025

Another study found that horses on a track system were more likely to graze in close proximity, mimicking the collective foraging behavior observed in feral horse populations. These subtle social and behavioral differences may have meaningful implications for welfare.
๐Ÿ“š Greening et al., 2017

๐Ÿฆถ ๐‡๐จ๐จ๐Ÿ ๐‡๐ž๐š๐ฅ๐ญ๐ก
When foot health, condition, and growth were assessed by a farrier, horses on the track system either maintained or improved hoof health, while those in the paddock system either maintained or showed a decline. However, the sample size was very smallโ€”six horses on the track and two in the paddockโ€”so while these findings are interesting, they should be interpreted cautiously until more research evaluates this topic with a larger sample size.
๐Ÿ“š Cameron et al., 2025

๐ŸŒ ๐„๐ง๐ฏ๐ข๐ซ๐จ๐ง๐ฆ๐ž๐ง๐ญ๐š๐ฅ ๐ˆ๐ฆ๐ฉ๐š๐œ๐ญ๐ฌ
Track systems have been shown to decrease soil quality due to the concentrated traffic patterns they create. These changes were mainly limited to the top 8 inches (0.2 m) of soil, and could be reducedโ€”but not entirely preventedโ€”by using paddock grids
๐Ÿ“š Hiltebrand et al., 2025

Another study found reduced vegetative biomass and greater sediment deposition from runoffโ€”both related to increased erosion. However, these differences compared a track system to pasture and did not evaluate changes in a conventional paddock system, which likely has similar traffic as a track.
๐Ÿ“š Farmer et al., 2023

More research is needed to further explore the environmental implications of tracks and paddocks with heavy traffic, however, providing footing with exceptional drainage, such as gravel or high traffic pads, may help reduce the rate of erosion.

Track systems appear to offer clear benefits in terms of movement, weight management, and behavior, with promising signs for hoof healthโ€”but they also come with trade-offs, particularly when it comes to environmental impact and maintenance needs.

For horses that cannot graze freelyโ€”especially those with metabolic conditionsโ€”track systems can be a valuable management tool. By restricting access to lush pasture while still promoting movement and enrichment, they provide a way to support these horses' physical and mental health without compromising their dietary needs.

Whether a track system or a traditional paddock is the better choice depends on your horses, your land, and your goals. What matters most is that the turnout environment supports natural behaviors, social needs, and overall healthโ€”whatever form that takes on your property.

I was surprised by how limited the published research on track systems still isโ€”especially given how widely theyโ€™re being adopted. Iโ€™ve recently been in discussions with a local barn about conducting a pilot study to evaluate track systems further, particularly their impact on movement and behavior.

Ever wondered if grazing muzzles do more harm than good? Read below to find out where your concerns should be!

What is the real risk to horse teeth and overall horse health from wearing a grazing muzzle? How does it compare to an at-risk (laminitic, obese, or metabolic) horse not wearing a grazing muzzle at all?

Most grazing muzzles don't have any negative effects on your horse's teeth. However, metal muzzles or slow feeders may cause damage in addition to excessive wear, chips, or fractures. There are also a few brands of grazing muzzles on the market made from a thick, hard plastic that can cause abnormal wear to the incisors. Many of the hard plastic grazing muzzles now offer softer inserts to minimize this type of damage.

The attrition that we appreciate to the incisors does have the potential to result in an exposed pulp, which could then result in pulpits or a tooth root infection. However, this is rarely the case. Generally, the teeth are able to repair themselves, by sealing off any exposed pulp, at a rate equal to or more rapid than the wearing process. This ultimately means that most of the cases that we see of abnormal wear to incisors from grazing muzzles is primarily cosmetic.

The risk of laminitis, on the other hand, is very real and the results can be catastrophic. Not wearing a grazing muzzle for even a few hours for a horse with EMS (equine metabolic syndrome) or PPID (Cushing's) can be problematic. Always follow your veterinarian's recommendations when managing your horse's metabolic issues, as these can and sometimes do have deadly complications.

If you have questions or concerns on if your equine should be wearing a grazing muzzle, contact your veterinarian.

Thank you to the Horse Owner Education Committee for providing this information.

This is why we recommend breaks during NBC travel โค๏ธ Happy trails!

Horses travel every day for a number of reasonsโ€”to be bought and sold, for competition, for breeding purposes, etc. Whatever the reason, horse owners should be aware of the complications that may occur due to transportation, including traumatic injuries, diarrhea, muscular problems, respiratory problems, overheating, colic, and even laminitis (in the case of overweight horses).

Following are a few tips to help your equine friend maintain good health and welfare during transport. This list is by no means complete and we encourage you to reach out to your veterinarian for additional advice when it comes to traveling with your horse!

โ€ข Be aware that inadequate management of feed and water intake during travel could cause colic, gastric ulceration and heat stress. Food and water should be provided prior to transport, during regular rest breaks and upon arrival at destination.

โ€ข Ensure your horseโ€™s immunizations are up to date against respiratory pathogens to protect your animal from these diseases.

โ€ข The horse should be rested before the journey, given rest stops during travel, and have time to recover on arrival at the destination.

โ€ข The vehicle should be well-ventilated to help prevent respiratory problems or overheating.

โ€ข Drive slowly and carefully (NO TEXTING, avoid driving when fatigued or eating while driving, etc.) to provide a comfortable journey for the animal and reduce the risk of injury and fatigue.

Happy trails!

I am starting to see some green grass which means it is time for the very important discussion about pastures and nonstructural carbohydrates!

The relationship between forage and nonstructural carbohydrates is a topic that is frequently discussed as it can be quite dangerous for a specific demographic of horse. It can also be rather complicated due to all the different variables involved, which is why I wanted to provide you with all the facts (and fun research) to help you learn more about them!

Nonstructural carbohydrates, often abbreviated as NSCs, are comprised of water-soluble carbohydrates (simple sugars and fructans) and starch. This class of carbohydrates is an important source of energy for the horse and they are digested and absorbed in the foregut, leading to an increase in blood glucose and insulin. As a result, high levels of NSCs in the diet can be an issue for horses with metabolic concerns specifically related to insulin dysregulation such as equine metabolic syndrome (EMS), Cushingโ€™s (PPID), and laminitis/founder. While NSCs can be more consistent and documented in manufactured concentrates, more variation is observed in pasture or hay due to outside factors such as plant maturity, time of day, and weather conditions.

In pasture plants, NSCs are produced via photosynthesis, a process in which sunlight, water, and carbon dioxide generate glucose and oxygen. A separate but complementary process known as respiration is responsible for breaking down the glucose created during photosynthesis and releasing that energy for cellular use. As a result, increased photosynthesis leads to an accumulation of NSCs and increased cellular respiration leads to decreased NSCs. There are many variables that can alter the balance between these processes in plants.

๐ŸŒ™ ๐“๐ข๐ฆ๐ž ๐จ๐Ÿ ๐ƒ๐š๐ฒ: During the day, or periods of sunlight, photosynthesis creates NSCs at a faster rate than respiration can utilize them. As a result, we often see our NSCs accumulate throughout the day. However, after the sun sets and photosynthesis ceases, respiration can begin to use up all these extra stores of NSC, causing them to decrease in the plant.

These findings are supported by a dissertation by McIntosh (2007) in which forage NSCs were generally lower in the morning and highest in the late afternoon. This can contradict some generalized recommendations suggesting horses should be turned out overnight. Since the NSCs will accumulate throughout the day, values are often highest around sunset. This means morning is likely a safer option when providing pasture access to limit forage NSCs. This is also why I donโ€™t like to use specific times to set recommendations but rather use the sun as my guide.

While this variable is related to the time of day, it can also be tied to weather conditions, such as cloudiness. McIntosh (2007) found a correlation between forage NSCs and solar radiation (r=0.62; P
