Grass-Fed vs. Conventionally Fed Beef
نویسنده
چکیده
Before making a comparison of grass-fed vs. grainfed beef it is necessary to first define these two beef types. An animal is considered grass-fed, according to the USDA Grass Fed Marketing Claim Standards, when grass and forage are the “feed source consumed for the lifetime of the ruminant animal, with the exception of milk consumed prior to weaning. Animals cannot be fed grain or grain by-products and must have continuous access to pasture during the growing season. Hay, haylage, baleage, silage, crop residue without grain, and other roughage sources may also be included as acceptable feed sources. Routine mineral and vitamin supplementation may also be included in the feeding regimen” (AMS, 2007). In contrast, grain-fed beef are animals which were deliberately fed grain during their lifetime.
