1) Do consider ease of loading.
Don’t discount slow feeding entirely due to the time required to load them. 10 minutes once or twice a day is a minimal time investment for your horse to have forage available 24/7.
2) Do provide access to forage 24/7. Meal fed individuals are typically anxious at feeding time which can result in the storage of body fat from stress and be more determined to eat as fast as possible. This can result in possible damage to teeth, gums and the slow feed device. Provide appropriate slow feeders to accommodate enough hay between feedings so there is always hay left. If your horse won't be "fed" for 12 or 14 hours you may need a bale net or multiple slow feed bags/nets in different locations.
Don’t expect any one slow feeder to have the capacity to provide a rate of consumption slow enough to provide forage 24/7 by offering limited amounts of hay; for example feeding 1% of body weight in a 24 hour period. If appropriate forage is available at all times they can typically eat more and maintain or lose weight by eliminating the stress associated with meals. A slow metabolic rate (body survival mode) created from forage restriction may take some time to speed up; include routine exercise.
3) Do offer multiple locations regardless of the size of the enclosure; mobility promotes gut motility, increases metabolic rate and allows them to choose where they are most mentally and/or physically comfortable. Horses enjoy foraging for food. They were not designed to be stationary for extended periods of time.
Don’t provide one location and expect voluntary movement.
4) Do experiment with slow feeders to determine the smallest mesh size (for overweight individuals) that enables your horse to extract hay without frustration. Frustration is counterproductive.
Don’t continue the use of any device that stresses your horse; stress/frustration elevates cortisol levels.
5) Do feed from ground level to enable a natural grazing posture and relaxed mental state.
Don’t mount or hang a slow feeder any higher than 4” off the ground for barefoot individuals. Hanging bags are not optimum but you can minimize adverse physical effects. If there will be a length of rope long enough for possible entanglement slide a piece of PVC pipe over the rope and attach a swivel clip at the bottom to hang the bag from.
6) Do offer tested low NSC (10% or below) straight grass hay for overweight individuals. Consult an equine nutritionist to ensure all vitamin/mineral requirements are being met in proper ratios and unique conditions addressed.
Don’t offer the only source of forage in a new slow feeder; feed as you normally would and offer the slow feeder in addition.
7) Do buy multiple slow feeders if you board your horse and fill them ahead of time if they are not willing to refill them. It’s a wise investment and you won’t spend anymore; a device that is used 25% of the time will last 4 times longer!
Don’t expect all boarding facilities to be on board with slow feeding.
Most slow feed manufacturers are willing to offer advice on how to maximize your slow feed investment; call them. A phone call may make or break the success of their product for your individual situation and goals. Take advantage of their knowledge and experience.
