Genetics Questions
How do I order ABS beef semen through Stone Ag?
Contact Brett Stone at 719-440-0189 or brett@stoneae.com. Tell him which sires you're interested in, how many cows you plan to breed and your timeline, and he'll handle the order and current pricing.
What is the difference between the ABS Sire Directory and the Focal Point?
The Beef Sire Directory is ABS Global's full spring catalog of beef sires. The Fall Focal Point is the fall update, with new sires added to the lineup and updated data. This page lets you browse both.
Does Stone Ag sell dairy semen?
No. Stone Ag focuses on ABS beef genetics for cattle producers in the United States.
Can Brett help me choose sires and plan an AI program?
Yes. Brett raises cattle and AIs his own herd, so he can help you pick sires that fit your goals and talk through synchronization and breeding-day logistics.
