Will elk eat hay?

I'm curious to know, does the question "Will elk eat hay?" hold any truth to it? Elk are known for their diverse diets, grazing on a variety of grasses and plants in their natural habitats. Hay, being a dried form of grass, seems like a logical extension of their dietary preferences. However, does their palate extend to include hay as a regular part of their diet, or is this a misconception? Could elk potentially consume hay in certain circumstances, or is it simply not a suitable food source for them? I'm eager to understand the scientific basis behind this question and whether elk truly do, or do not, eat hay.
