Amount of meat off 1 cow

A 1200 steer, ½ inch fat, average muscling, yields a 750 pound carcass.  The 750 pound carcass yields approximately:

• 490 pounds boneless trimmed beef
• 150 pounds fat trim
• 110 pounds bone

A specific example of how the 490 pounds of boneless, trimmed beef could break out includes:

• 185 pounds lean trim, or ground beef
• 85 pounds round roasts and steaks
• 90 pounds chuck roasts and steaks
• 80 pounds rib and loin steaks
• 50 pounds other cuts (brisket, flank, short ribs, skirt steak)

CONCLUSION:

1 person eats on average 14.5 kg of beef a year
1 cow = 222.26kg

15 people can eat 1 steers meat
