U.S. beef imports from Mexico have at least doubled in each of the last 2 years, continuing an upward trend that began in 2003 (fig. 1). The impetus for the increased imports is beef from Mexican Tipo Inspección Federal (TIF) plants and increased production of grain-fed beef, the quality and type of beef U.S. consumers prefer. The increase in coarse grain domestic feed use in Mexico, in addition to increased exports of U.S. feed and distillers’ grains, is evidence of the shift toward fed beef in Mexico.
