It just occurred to me. If I know exactly where my milk comes from, I could find out exactly what my dairy cows eat.
My milk comes from dairy cows that eat: Alfalfa hay, barley, wheat, coastal grass hay, corn, ensiled forages, native grass, hay, pasture, peanut grass hay, prairie grass hay, soy bean meal, soy hulls,vitamin and mineral supplement.
Also, the cows are able to go outside 365 days a year. That's all cool with me.
