Adjustment for Thin Daily Ration Ewes with a Score of 1 Period Desired Score (air dry, lb.) to Low 2Adjust feed for "fat" (score 4) and "obese"(score 5) ewes only during early gestation by reducing intake to 75-80% of normal. 10-15% weight loss can be tolerated. For a 150-lb. ewe to move up on condition score, she will need to gain 5 to 10 pounds.

The five condition scores (figure 3) are:
Condition Score 1: Very thin Spinous process very prominent and sharp; transverse process also easily felt and sharp; fingers can be pushed easily under ends; loin muscle shallow, concave; no fat over muscle, under skin.
Condition Score 2: Thin Spinous process prominent but less sharp; transverse process smoother on ends; fingers can be pushed with little pressure under ends; loin muscle more depth and fullness; no discernible fat covering.
Condition Score 3: Average Spinous process easily felt with finger pressure but smooth not sharp; transverse process smooth and fat covered; firm pressure needed to push fingers under edge; loin muscle full with cover of .15-.20 inches of fat.
Condition Score 4: Fat Spinous process can be felt with considerable finger pressure; transverse process cannot be felt, ends covered with fat; loin muscle full with cover of .25-.35 inches fat.
Condition Score 5: Very fat Spinous process cannot be felt; back broad with hollow; transverse process cannot be felt; loin very wide and thick over loin edge; evidence of fat around dock extending forward on rump. Fat covering over .4 inch over loin muscle, 1.0 inch or more over rib.
