Horsemaster® Pro is a mixture from our Master Series especially made for horse pastures. Because horses have both upper and lower teeth, they graze the grass close to the soil. Also, horses are very active animals and put a lot of traffic pressure on grass. With these facts in mind, Barenbrug developed Horsemaster Pro. Different mixtures have been composed for different climates, but all mixtures include at least timothy, orchardgrass, and ryegrass. Horsemaster Pro is guaranteed endophyte-free.
