Embryo Donor Dams

L-R:  RL Mandate Lady 2981, RL 0145 Image 102, RL 109 In Focus Lass 606S


RL 0145 Image 102 in 2018

RL 0145 IMAGE 102

RL 0145 Image 102 is a pathfinder dam and the original cornerstone of our embryo transfer program.  Her first natural calf,  RL 9061 Birdie 3102, is the dam of Stevenson Big League, Stevenson Declaration and Stevenson Republic, Rock Lake herd sire. 


This cow has been in our donor program for 5 years with 44 calves on the ground and more on the way. She is a true brood cow with a near perfect udder at 11 years of age.   She has a 109 weaning ratio and 7 natural calves. 

RL MANDATE LADY 2981

RL Mandate Lady 2981 is one of our favorites. Moderate frame, great feet and udder and very fertile.  She is a triple threat with calving ease, strong growth and carcass quality.

7Z MANDATE LASS 2602

This pathfinder dam has been a great cow for us. She has proven very fertile with great feet and is highly maternal. Her dam, 7Z Sensational Lass 602 is a legend. She was nearly 23 years old when she passed in the fall of 2018. Also a pathfinder, her perfect calving record on 15 natural calves and a 106 weaning ratio proves what an exceptional dam she was.

RL 109 In Focus 606S is the granddam of Stevenson Big League, Stevenson Declaration and Stevenson Repbulic, Rock Lake Angus herd sire.
