The ram lambs are the heaviest and oldest. They ranged in weight from 40.4 to 80.3 lbs. and averaged 61.2 ± 11.5 lbs. The median weight was 64.4 lbs. Birth type averaged 1.89. Age of the ram lambs ranged from 60 to 95 days and averaged 81 ± 10 days. The median age is 78 days.


The wethers are the most numerous group. Twenty five ranged in weight from 36.0 to 76.4 lbs. and averaged 55.7±  9.1 lbs. The median weight was 56.2 lbs. Birth type averaged 1.71.  Age of the wethers ranged from 61 to 95 days and averaged 77 ± 7 days. The median age is 76 days.

The short-scrotum rams are the youngest and intermediate in starting weight. Seventeen ranged in weight from 41.4 to 68.6 lbs. and averaged 56.2 ± 7.7 l bs. The median weight was 55.2 lbs. Birth type averaged 1.69. Age of the short-scrotum rams ranged from 60 to 95 days and averaged 76 ± 8 days. The median age is 74 days.
