The research article I will discuss this month explores horse preference for different grass species when made into hay.

Mastellar and colleagues at the Ohio State University in 2019 and 2020, aimed to compare seven cool-season grasses in terms of hay yield, nutrient and ergovaline levels, and relative preference by horses.
