How to Measure Pasture Intake When Your Horse Wears a Grazing Muzzle
Grazing muzzles are useful for reducing your horse’s pasture intake. They can be used for easy-keepers when you are trying to reduce energy levels within the diet. Or when your horse suffers from a health condition which requires a reduction of non-structural carbohydrates (starch + sugar) in their diet. Grazing muzzles have gained popularity with many horse owners as they allow their horse to socialise, exercise and be continually stimulated through grazing.
Studies have shown grazing muzzles can reduce forage intake by as much as 80%. There are many factors which affect intake including acclimatization to the muzzle, pasture height and type of muzzle used and your individual horse’s tenacity when it comes to getting grass to poke through the hole.
To enter pasture intake in FeedXL when your horse is wearing a grazing muzzle, subtract up to 80% from the time your horse spends grazing. For example, if your horse is allowed to graze muzzled for 15 hours and is dry-lotted the remainder of the time, you might enter ‘3 hours’ as the amount of time your horse ‘grazes’ into FeedXL (80% of 15 is 12 hours; 15 x 0.8 = 12 hours: 15 – 12 = 3 hours of ‘grazing time’.
Observe your horse grazing pasture while muzzled and watching his body condition over time. This will allow you to get a better estimate of actual intake by your horse. You may find that reducing the ‘time’ grazing in FeedXL by 80% is too much, so adjust it as you see fit.
