My ponies are on dry lot. Our hay primarily comes from Pennsylvania. Does anyone know if Selenium and Manganese are high or low and if we need to supplement or not?

My most recent hay analysis doesn't report on selenium. For manganese it states, "as sampled - 43g per pound and dry matter - 47g per pound". I don't know how to interpret if that is a lot or is lacking. Thank you in advance for your guidance.

Thank you,
Robin
