About Us

TSG has over 25 years of experience. It is an independent stud, working with several genetics companies. In collaboration with our genetic partners, we work to fulfill our Mission: "Supplying superior quality genetics through top quality semen along with excellent customer service".

Swine A.I. is a fast-evolving field of science. To keep pace with new learning both Arnold and Stu attend conferences and are in regular contact with industry leaders across Canada, the U.S. and around the world. Both men are committed to the continuous learning required to ensure their customers benefit from the most current and sound, science-based practices that they put in place at TSG.

Staff Arnold

Arnold Ypma has been working with pigs his entire life. After building his own swine herd, he developed a genetic line (Shade Oak Duroc). When swine A.I. was a new idea, he began a boar stud focusing on quality product and superior customer service. His ability to breed and select superior genetics was realized with the sale of the Shade Oak Duroc line to Hypor Genetics in 2009. Arnold continues to operate a farrow to finish swine herd with his sons, using TSG semen and retains an active role in the management of TSG.  


Stuart DeVries was raised on a pig farm, studied agricultural economics at the University of Guelph and got to know many producers in his 7.5 years of marketing hogs at Ontario Pork. His farming roots give him an understanding of TSG’s customers and their business reality. Stu knows well the impact of good reproductive results on the farm’s bottom line. Over his  almost 20 years with TSG he has acquired knowledge from many leading genetic and reproductive specialists. Helping TSG customers to troubleshoot and improve on-farm results is an aspect of his work that he genuinely enjoys.
