Top 15% of the breed for CE, top 15% BW, top 30% Milk, and top 20% MCE, yep, these numbers belong to 53D, the son of BW trait-leading Pete 203Y.  Born with a moderate birthweight of 84 lbs, he muscled quickly and grew stout with good natural thickness and ample performance.  He weighed well at both weaning & yearling.  We recommend using 53D on heifers also.
