Joseph is well versed in breeding and shot protocols. Also Joseph assists Dr. Ramon Tosta with OPU and Embryo transplant.
Joseph learned to AI at Hilmar High School where he took ag classes all 4 years of high school practicing on animals donated to the school. Joseph then formally joined the AI industry through his uncle who had been an AI technician for 25+ years in the surrounding area. He has been a certified AI technician since 2008 who owned and operated a successful breeding business for 13 years. Spending his first years on his route, in the Petaluma, Ca area then moving back to the Central Valley to begin raising his family. In his career Joseph has bred over 100,000 animals.

Dr. Christian Vigneault, Ph.D.
Christian Vigneault, Semex’s Director, Reproductive R&D, obtained a BSc in Biochemistry at Laval University in 2001, followed by his MSc and PhD in Animal Science specializing in gene expression in bovine in vitro produced embryos.
He began an industrial postdoctoral internship at Boviteq in 2007, with the goal of creating a new IVF (In Vitro Fertilization) system to produce freezable IVF bovine embryos. Following the successful implementation of that new IVF system, he was hired into a research and development position at Boviteq, working on the development of a suite of media that would allow for the movement of oocytes and embryos through couriers.
This research allowed Boviteq to expand activities through satellite locations in Canada in 2012. In 2013, Christian moved to Madison, Wisconsin to launch Boviteq in the US. He returned to Canada to supervise Semex’s Research & Development Team and was been assigned to lead the semen research in 2014.
Christian also led a team that researched, investigated and diagnosed Semex’s fertility position in 2016, leading to the Fertility First protocols and campaign that launched in 2018. His current position as Director, Reproductive R&D, specializes in ensuring each department within Semex’s laboratory and research teams are working in harmony and reaching their absolute fullest potential.
