Horse Slow Feeder Guide:
How to Use, Safety, Tips, and More
Finding the best feeding regimen for your horse can be a challenge. Just like humans, different horses can require different things to thrive; this can be even more difficult if you board your horses. Not every barn owner or manager is open to unique feeding regimens, which can include dietary restrictions, preferences for particular feeds, or specifically timed feedings.
If you're a horse owner or lessee, then you have probably heard about slow feeders at some point in your equestrian journey. Although there are no formal studies on the success of slow feeders, most equestrians are in agreement that they offer more benefit than harm. Slow feeders are designed to mimic a horse's natural habits of eating consistently, instead of limiting them to two or three "meals" throughout the day. One of the many benefits of a feeding regimen that feels more natural to your horse is reduced anxiety.
However, before you introduce a slow feeder, ask yourself: Does my horse even need a slow feeder? Which slow feeder would be best for my horse? Does a slow feeder make sense with my barn, paddock, or pasture setup? If you do choose to get a slow feeder for your horse, there can be safety concerns and doubts about how to use it correctly. We will be addressing these points and reviewing some favorites from the knowledgeable RW Crew in this article!
Best Slow Feeders for Horses
First off, there are important factors to keep in mind when choosing a slow feeder; it is not a one-size-fits-all solution! Material, hole size, hay type, and horse age all influence your equine's comfort or irritability during their hay consumption. If your horse is destroying your slow feeder or eating too quickly (continuing weight issues), it is time to reexamine your slow feeder and hay combination. Please refer to the handy chart below for a general guideline:
| Hole Size | Hay Type | Horse Age/Size |
| 0.5" - 1" | Grass, Chopped, Medium to Coarse Hay | Minis, Ponies, Donkeys, Mules, & Indulgent Horses |
| 1.5" | Longer Grass, Chopped, Alfalfa, Bermuda, Fine Hay | Young & Most Horses (Used to Hay Nets/Bags) |
| 1.75" - 2" | Grass, Timothy, Alfalfa, Forage, Thick to Coarse Hay | Anxious & Older Horses, Drafts, Warmbloods |
| 3" - 4" | Long-Stemmed, Straw, All Hays | Special Needs/Senior Horses/Cattle |
Finding the right feeder and hay combo may require some trial and error. Horses have different learning speeds, personalities, and patience when it comes to slow feeding. Be prepared to invest time, money, and effort into helping your horse accept the concept, especially if you are introducing the concept for the first time.

A reinforced, durable mesh construction makes the feeder sturdy enough for even the most enthusiastic of eaters, while providing a safe slow feeding experience for laminitic horses and all of their equine pals!
Benefits of Slow Feeders for Horses
A slow feeder is designed to imitate a horse's natural 24/7 grazing behavior with free-choice foraging when access to fresh grass isn't available. Slow feeders are wonderful tools to balance calorie intake when your hay does not quite meet your horse's nutritional needs. Increasing chewing time through slow feeding can help with improving behavioral responses, lowering ulcer risk, and managing hormones. If your horse is already getting its proper calorie intake and nutritional needs met through your current feeding program, we do not suggest changing the system (especially if your vet or equine nutritionist approves)!
For easy keepers or overweight horses, slow feeding helps regulate insulin and metabolism fluctuations that contribute to putting on pounds. Slow feeding improves digestion and the absorption of calories and nutrients for underweight horses as well. This feeding method can also be a great option for horses that eat their hay down quickly and then exhibit negative behaviors from boredom.
The main purpose of slow feeders is to increase chewing time while controlling calorie intake with your horse's self-regulation. When used appropriately, horses that are transitioned to free-fed forage through slow feeding can eat more and maintain or lose weight at the same time. As equestrians all know, a well-balanced nutrition plan is essential to your horse's life!
How to Introduce a Slow Feeder to Your Horse
When introducing slow feeding to your horse, we highly recommend going slow! It is best to avoid making feed changes without proper research and planning, as this can add food-related stress to your horse's life. To reiterate, the overall goal is to provide your horse's daily hay requirement through 24/7 forage access. Your horse needs to go through a learning process to know that there will always be hay available through slow feeding. Patience and consistency will help maintain your horse's mental and metabolic health.
- Be sure to provide loose hay for your horse upon initial introduction. Feed your normal portion, but give 3/4 of the hay loose and the rest in a slow feeder that has larger holes (we recommend starting with a slow feeder with 1.75" - 3" holes, depending on equine age).
- Continue to provide a portion of loose hay for about two weeks to a month. During this time, start cutting back on the amount of loose hay given while adding more hay to the slow feeder as a secondary food option. Having an additional slow feeder with smaller holes (1" - 1.5") will help overindulgent horses as they learn.
- At some point, your horse should start to prefer eating from the slow feeder. Switch to exclusively feeding your horse from a smaller-sized slow feeder or two. Some horses may refuse to eat if they become especially frustrated by a too-small hole size, so monitor their eating behaviors.
- Once your horse is slow feeding without any food-related stress, you can transition to an even smaller hole size that holds a larger portion of hay. Most horses do well long-term on 1" - 1.5" sized holes.
- Your horse needs to learn self-regulation through this gradual transition to be less prone to overeating in the beginning, which can lead to colic. Having multiple slow feeders in several locations with various hole sizes for different hay types promotes your horse's movement as well.
If you are feeding tightly flaked hay such as alfalfa, you can pull it apart when putting it in your slow feeder to help reduce frustration. Slow feeding low to the ground or from the ground induces a more relaxed, natural state; if on the ground, protect your slow feeder from excess dirt or damage with a bin (especially if your horse is shod). If your horse is still eating too quickly or gaining too much weight, cut back on the hay portion you are feeding and restrict their intake with a smaller hole size.
It is easier to purchase several slow feeders that hold larger portions of hay (such as a full bale), so you have to refill them less often. Your horse will eventually realize they will consistently have food access.
Horse Slow Feeding Tips & Tricks
Introducing your horse to a slow feeder can be a process! Read on for some tried and true tricks from our savvy RW Crew.
Slow Feeding Tips
Have Multiple Slow Feeders: We strongly suggest having at least two slow feeders per horse, even if stalled together. Having multiple slow feeder locations offers a more steady flow of forage and encourages your horse's natural tendency to move around to graze. Always be sure your slow feeders are secure.
Select the Right Hole Size: Selecting your slow feeder hole size can be tricky. One factor is the size of the horse's muzzle and whether they can use their lips and teeth to get hay out of the hole openings. Typically, it comes down to how quickly the horse tends to eat. Horses that inhale their hay will be likely to do well with smaller openings long-term. It's not a bad practice to have a variety of hole sizes on hand, so you can swap different feeders per season depending on how your horse carries weight in the colder and hotter months.
Repurpose Your Training Feeders: You can continue to repurpose your initial slow feeders with larger holes for trailering, showing, or camping; there is no need to toss them once you transition your horse to a smaller hole size! Traveling tends to induce some stress in horses, and providing a slow feeder with larger holes for easier access can alleviate additional stress.
Add a Digestive Supplement: Because your horse will be consuming more hay than normal with the slow feeding method, adding a digestive aid will help them more efficiently break down their food and better process the hay nutrients. A digestion or gut health supplement can also help reduce the potential of colic!
Slow Feeding Safety Tips
Material Matters: Avoid metal or steel mesh grates as these can cause dental issues with long-term use. It is better to opt for feeders with soft or flexible constructions.
Slow Feeder Placement: Be mindful of height placement. Horses are designed to eat off the ground. Long-term feeding with their head elevated can cause physical ramifications and potential respiratory issues.
Prevent Injuries: Feeders can get caught on shoes and around legs if not secured well, which can cause life-threatening injuries. When using hay net styles, run the extra string through the bottom of the net and use a clip to attach it back to the net itself. Doing so helps keep your feeder elevated off of the ground after becoming empty.
Maintenance is Key: Check slow feeders daily for damage. Rips and tears can create areas that can entangle a horse in dangerous ways. Make a habit of inspecting them every time you feed to ensure they can be repaired or replaced before causing an issue!
Introducing a Horse Slow Feeder - A Review from Crew Member Alison
RW Crew member Alison grew up riding horses on the Central Coat of California, and had always fed her horses loose hay twice a day. Due to her horses' food-aggressive tendencies, she decided to see if the switch to slow feeding would ease their anxiety around feeding. Read on to learn about her experience introducing her horses Scout and Bellizo to slow feeding!
Initial Introduction
Upon the initial slow feeder introduction, both horses received a portion of loose hay for about two weeks. Alongside their loose hay, they received feed in the Tough1 Large Slow Feed Double-Sided Web Hay Net. The 2" x 2" hole size of this feeder was ideal for the horses to eat from at first, preventing them from becoming too frustrated. With their destructive behaviors, I was impressed by how well these hay nets held up to being banged around by Bellizo and Scout. I will admit that both horses stuffed themselves and got porky, as they did not yet understand the idea of hay readily being available to them!
Experience and Behaviors
Their loose hay portion was taken away to further slow them down. With being exclusively slow fed, the Tough1 feeder was replaced by the Shires Greedy Feeder Slow Feed Hay Net 1" and Freedom Feeder Single Day Slow Feeder Hay Net. Having more feed always available to them, they did begin to slow down a bit. Over time, both horses showed that they preferred to eat from the 1" hole size. Bellizo and Scout continued to express some agitation while watching the rest of the horses receive their morning and evening feedings. They still thought they were on the same loose hay schedule!
Bellizo is a particularly intelligent horse, and he figured out after about a month that he could walk away from his food and it would still be there when he came back. He has especially slowed down to now enjoy the mental stimulation slow feeding provides him! I noticed Bellizo was more trusting with me around his food; I could safely go in and out of his pen with the slow feeders without him really being bothered. He chews on the fence less and can instead burn off energy and boredom grazing from the feeders.
Scout is still devouring his food. At the rate he was eating, he burned through an expensive amount of hay trying to figure out the concept of slow feeding. Being quite young, he is taking longer to understand that he does not need to stuff himself and can safely eat in peace! On the other hand, Scout paces less and has thankfully stopped chewing the fences. The slow feeders themselves have given him a more productive outlet for his anxious energy and have helped him eat at a healthier pace.
Slow Feeding Feedback
The time invested into filling the slow feeders took longer than expected. It is easier to have a few feeders on hand to provide several grazing positions for the horses, but also to prep ahead of time—ready to replace any empty hay nets. The bigger the hay holding capacity, the less frequent refilling is, although a larger hay capacity also means a heavier weight. Depending on how your horse is stalled, it might be a bit difficult to maneuver a heavy slow feeder around. Durable hardware makes a big difference in helping secure the feeders.
Overall, transitioning my horses to slow feeding was a wonderful learning experience that I would go through again. If it is approached with an open mind, knowing time and money will be spent, slow feeding is a great way to address your equine's nutrition or eating habits. Being flexible and listening to what your horse is telling you will result in an improved equine relationship!
Frequently Asked Questions
Will my boarding barn allow a slow feeder?
It's a good idea to speak with your barn management before buying a slow feeder. While it is up to the horse owner on what kind of feeding regime they feel is right for their horse, barn management can refuse to allow them; this is typically not done to be difficult, but barn staff can work long and hard hours for not a lot of money. If every horse in the barn has a special feeding program, it can easily add hours to the workday. Talking to your barn management about the type of slow feeder you want to use and whether it would be feasible is considerate, and it may warm them up to the idea! If considering a pasture slow feeder for a shared field, be prepared for rejection unless all horse owners involved agree to use slow feeders.
Listed below are a few options to consider for happy staff at your barn:
- Purchase more than one of the same slow feeders and offer to regularly prep them, so the staff can simply deliver them like normal hay feedings.
- Be open to exploring a different slow feeder type if management thinks your pick will be too much extra work for the staff.
- Be willing to consider paying an additional fee for added work for the staff.
When boarding, the barn staff helps make our horse's world go 'round! We recommend including them in your slow feeder decision, so they can offer their insight while feeling appreciated. It's a triple win when all participating parties can feel happy and cared for.
My horse is getting aggressive during feeding time, would a slow feeder help?
Slow feeders are helpful in managing aggressive food behaviors in horses. Bad habits like cribbing are usually caused by underlying issues, such as boredom. Slow feeders give bored or aggressive horses a positive energy outlet. Ulcers can be caused when stomach acid levels rise due to too long a time between feedings, leading to other negative behaviors. Slow feeders give your horse a steady feeding schedule to help protect against ulcers and their side effects. Horses that are anxious during feeding times can develop food-related stress. Slow feeders provide constant access to food and, therefore, can help lower stress levels and prevent poor or aggressive behaviors.
What hole size do I choose?
It is best to choose a hole size that will slow down eating to mimic the grazing effect, but not one small enough to cause exasperation in your horse. If your horse is refusing to eat at all with a slow feeder, they are likely too frustrated. It is best to introduce slow feeders with a larger hole size, then move to smaller holes after your horse adjusts to the slow feeder concept.
Are slow feeders safe for horses?
Slow feeders are quite safe when used properly. It is important to purchase a hay net or bag that is made of high-quality materials to prevent breakage of the feeder or hazards to your horse. Be sure the slow feeder is secured to prevent swaying, and any excess rope or straps are tucked away. Shod horses can get shoe nails stuck or shoes pulled off if snagged on a hay net; make certain your slow feeder is hung high enough to prevent entanglement, but low enough for a normal eating position. Improper height placement can cause neck and back issues in your horse. If you feel a slow feeder hay bag or net is not quite right for your horse's feeding environment, we encourage you to learn more about the different Types of Horse Feeders.
Are hay nets bad for your horse's teeth?
Hay nets are not bad for your horse's teeth as long as they are high-quality nylon or polyester and are not constructed from steel, wire, or metal parts. However, that is not to say that metal feeders or grates are necessarily detrimental to your horse's dental health. Slow feeding can actually help manage dental risks caused by underlying conditions, such as laminitis or high-sugar diets. If your horse does experience any dental issues with a hay net or slow feeder, please consult your veterinarian immediately.
Closing Thoughts
Introducing a slow feeder can greatly improve your horse's health by promoting a more natural grazing pattern. We all wish we could provide our equines with ample amounts of land covered in healthy grass to graze on, but that just isn't the reality for most horse owners. Some horses have injuries and other health issues that make this impossible, but their digestive system still functions best on continuous grazing. Slow feeders can improve behavioral responses, prevent and manage issues, as well as promote a healthy weight. This is made possible by simply giving your horse the ability to eat the way nature intended, with a little help from the technology of slow feeders!
If you are considering trying slow feeding, we strongly encourage speaking to your vet or equine nutritionist before changing your horse's current feeding program.
