High Fibre HorseHage is made from selected ryegrasses, which have been allowed to mature before harvesting to attain higher fibre, lower protein and lower energy levels. Because it is low in energy, High Fibre HorseHage is generally suitable for Riding and Pony Club horses, native ponies, veterans and those that are resting, convalescing or are laminitic.
