Semex is pleased to announce that Ryan Lett will succeed David Mayo as General Manager of Semex New Zealand, coinciding with David’s retirement on June 30, 2025

A well-respected industry leader, David began his work at Semex as the Semex Australia Area Manager for NSW and Queensland in 1996. In 2002, following the acquisition of the New Zealand market, David was appointed Market Development Manager, assuming a dual role between the two countries. In 2015, he became General Manager of Semex New Zealand, a position he has held to this day. Additionally, he served as General Manager of Semex Australia following the retirement of former General Manager Jim Conroy in 2018, a role he held until 2022.  

David’s extensive leadership helped build the market for Semex in both New Zealand and Australia, as he assembled and managed strong, enthusiastic teams. Reflecting on his time at Semex, David says, “Semex is and always has been a tremendous company to work for. The team environment created by its leadership has always been a highlight for me, along with the great people I have worked beside on a day-to-day basis.”

Ryan Lett succeeds David as General Manager in New Zealand, bringing over 14 years of experience with Semex and the New Zealand team. He initially served as a Product Support and Area Manager, then transitioned to North Island Manager, and in 2021, he was named National Sales Manager. 

During his tenure, Ryan has worked closely with the New Zealand team and received mentorship from David Mayo and Jim Conroy, the former General Manager of Semex Australia. Ryan is excited to continue delivering Semex’s progressive solutions and genetics to this growing market.  

“David has contributed a tremendous amount to the development and current success of Semex New Zealand,” says John McDougall, ... Read More...

Boviteq is thrilled to announce opening a cutting-edge OPU (Oocyte Pick-Up) satellite facility and IVF (In Vitro Fertilization) lab at Arizona Dairy Company in Gila Bend, Arizona. This marks a major milestone in expanding world-class reproductive technology in the US Southwest.

“The team at Arizona Dairy Company has been a driving force in advancing IVF in large-scale dairy production,” says Dr. Shantille Campbell, Boviteq’s Director of Embryo Business Development. “They’ve been bold, innovative partners who consistently push the limits of genetic improvement. It was a natural next step to open a lab tailored to their growing needs.”

Founded in 1973, Arizona Dairy Company is a multigenerational, family-run dairy milking 3,250 registered Holsteins three times a day. The operation is known nationwide for producing elite genetics, emphasizing long-term sustainability and cow longevity. Hadley Ross, OPU Program Manager, leads the new IVF facility and represents the sixth generation actively involved in continuing their legacy of excellence and innovation.  

With Arizona's only IVF lab of its kind, the dairy has become a leader in producing high-quality Holstein genetics and beef embryos from its top-performing cows.

“We began IVF work with our top 5–10% based on TPI, NM$, udder composite, and feet & legs—our best cows—and thought, ‘Let’s make more of her!’” says Justin Stewart, Co-Owner of Arizona Dairy Company. “For us, the perfect cow is efficient, low-input, and consistent. She breeds back year after year and delivers milk, fat, and protein easily.”

"Boviteq has elevated our embryo production and reliability to the highest level. They are easy to work with, thorough, and assist us at every step of the way to ensure the maximum number of embryos per donor possible,” says Justin.

Boviteq is thrilled to announce opening a ... Read More...
