My oldest cows are 9 and 10 years old, my herd started with bred heifers from when basin abgus dispersed and they were all defect carriers that have been shuffled out of the herd so these oldest cows have been here from our start. The 4 best among them have milk epds of 36, 36, 32, and 28. Aside from one slough there has been 1 3rd cycle calf and 1 2nd cycle calf and the other 30 have been AI calves so I would say they have bred up fine with some pretty high milk epds
