THE TESTAMENT SIRE GROUP
Here is the first son of the impressive JWC Blackbird Lady 219K to ever sell! This is a powerful cow family that is up and coming in the program, and stems back to the maternal power of the GAF Blackbird Lady 1159 donor that has been stirring up a storm for the JWC brand. In their 2024 production sale, two daughters of 1159, one being a full sister to the dam of WINC Testament 5134N were sought after by the most serious of stockmen. The W/C Bankroll 811D daughter of 1159 sold to Beitelspacher Ranches. This homozygous polled and homozygous black stud is one that will catch the attention of stockmen that place value in good built stock.

WINC Testament 507N is a calving ease prospect that comes with both a genomic profile and phenotypic build that should leave a rancher some peace of mind that his first calvers and young females are in good hands. Beyond his top 20% CED and 25% BW figures, 507N comes with a homozygous polled and homozygous black genetic profile, and comes with a very impressive TI index that denotes him as a leader of the class for his opportunity to sire terminal advantages. Check out his monster 17+ inch ribeye area measurement.
