Feeder Cattle Standards are :

• Common trade language between buyers and sellers.

• A tool for penning cattle at officially graded sales.

• Used to certify feeder cattle grades for futures contracts.

• Basis for federal-state livestock market news reporting.

U.S Standards for Grades of Feeder Cattle

• Grow rapidly and efficiently

• Produce a carcass with acceptable quality and high cutability.

• Adequate frame • Body capacity

• High lean to fat ratio up to market weight

• Muscle without excess fat

• Thrifty• Healthy• Acceptable structural

correctness

Growth and Development of Bone, Muscle and Fat

Choice

• The standards describe the various types of feeder cattle being produced and are used as a basis for market reporting and as a common trade language between buyers and sellers.

• Updated October of 2000 to reflect changes in the genetic composition, production, marketing and management of beef cattle.

U.S Standards for Grades of Feeder Cattle

U.S Standards for Grades of Feeder Cattle

• Feeder Cattle are evaluated by a combination of :– Frame Size– Muscling

Frame SizesLarge

Medium

Small

U.S Standards for grades of Feeder Cattle

• Under ordinary development and feeding conditions, different framed animals reach slaughter potential at different weights.

Frame Size- Large

• Tall and long bodied• ½ inch fat:• Steers finish > 1250 lbs• Heifers finish > 1150 lbs

Frame Size- Medium

• Slightly tall• Slightly long bodied• ½ inch fat:• Steers finish 1100 to 1250 lbs• Heifers finish 1000 to 1150 lbs

Frame Size- Small

• Not as tall as Medium• Short bodied• ½ inch fat:• Steers finish < 1100 lbs• Heifers finish < 1000 lbs

Inferior – This grade will include sick unthrifty cattle and double muscled cattle due to their inability to Quality grade.

• Weight– Accuracy and

completeness for selection

• Frame Size– Finish early and at a

lighter weight– Earlier maturity at

desired fat thickness•Muscle Thickness at a given fatness is highly correlated with muscle to bone ratio.
