No animals are ever given artificial growth hormones or stimulants and are guaranteed to be free of antibiotics. Marin Sun Farms guarantees that all ruminant livestock are grass-fed and pasture raised their entire lives, with no consumption of grain, by-product supplements, or ever setting hoof within a confinement feedlot. Non-ruminant, mono gastric, omnivorous chickens are pasture raised and allowed to choose their diet from the pasture and supplemental grains.
