[QUOTE="Katpau, post: 1650057, member: 9933"] Breed average of current sires for birth weight is +1.3 and calving ease is +6, so he is +1.9 pounds over today's breed average on birth weight and 1% over today breed average on calving ease. Breed averages were established at various dates in the past, and today's sires are compared to those numbers. Birth weights are expressed in pounds, and the breed average was set at 0 in 1984, so the average birth weight is now 1.3 pounds greater than it was in 1984. Calving ease is expressed as a difference in percentage of unassisted births, with a higher value indicating greater calving ease in first-calf heifers. This number was set at 0 in 1982-1983. Since then the average percentage of heifers requiring assistance has dropped by 6%, so that 6 is today's breed average. [/QUOTE]
