Let’s talk muzzles!
At Absolution Equine, grazing muzzles have a significant role in our program.
There are numerous benefits to using grazing muzzles, those being:
1. Grazing muzzles help regulate and reduce forage intake. On pasture, grass intake can be reduced by an average of thirty to eighty percent with the use of a muzzle making them an effective tool for controlling weight and sugar intake. Though this is a large margin in reduction, different styles of muzzles have different results with different horses.
2. Grazing muzzles aid in disease prevention! A common disease caused by unregulated pasture intake is laminitis, which is a very painful and often times chronic disease when left unmanaged. As well as laminitis, grazing muzzles are effective tools for horses with equine metabolic syndrome (EMS), Pituitary Pars Intermedia Disorder (PPID/Cushings), and insulin resistance, which are often overlooked precursors to laminitis.
3. Grazing muzzles can increase foraging behaviors and movement throughout pastures while horses seek out grasses and other material to ingest that will fit through the muzzle.
4. Grazing muzzles are helpful in supporting digestive stability, as they are, in principle, slow feeders that are worn rather than placed within the environment itself. They allow horses to forage for longer periods of time on both pasture and hay with a lower likelihood of gorging.
5. Because horses are unable to pull vegetation from the roots while wearing a grazing muzzle, they are great tools for reducing the erosion of pastures and improving the overall quality of forage.
While there are numerous benefits to grazing muzzles, there are several disadvantages which are as follows:
1. Assessing the safety of your grazing muzzle is important! At the end of the day, your horse will be wearing a halter in turnout for an extended period of time. It is never recommended to use a halter without a breakaway mechanism, such as a leather poll strap, with a muzzle.
2. Ensuring that your muzzle is properly fitted is extremely lucrative. Grazing muzzles that are too tight can cause restricted movement of the mandible, rubbing of the hair and skin, and potentially cause dental wear. Grazing muzzles that are overly large may allow for over grazing, as horses will be able to “tip” the muzzle and consume more forage through the sides.
3. Dental wear is not necessarily common but may be observed more with certain muzzle designs, such as those designed with harder materials.
4. Understanding which muzzle makes most sense for each individual horse may be difficult and often times requires some trial and error. Miscellaneous straps, inserts, padding, tape, and other materials may be used to prevent rubbing, removal of the grazing muzzle, and to improve overall fit.
5. Ensuring that the grazing muzzle you choose is compatible with the water source that your horse has access to it extremely important! Grazing muzzles that are made with firm materials will make drinking from automatic waterers difficult or impossible. For horses with automatic waterers, we recommend a grazing muzzle designed with a more pliable material to allow for easy access.
We feel that the advantages of grazing muzzles far exceed the disadvantages, which are easily mitigated through correct fitting and management.
While there are many designs of grazing muzzles on the market, we routinely use ThinLine’s “Flexible Filly” grazing muzzle for our personal herd, as well as many of the horses that have been and currently are in our care. This specific muzzle design is made with soft, highly-pliable material that is durable, lightweight, breathable, and easy to clean.
