Your Genetic Connection


Friendly. Organized. Experienced.

Interglobe Sire Services, LLC, formerly Interglobe Genetics, is one of the most well-respected semen collection centers in the nation. Located in Pontiac, Illinois, former owner, Bill Nolan, began this AI operation in 1975. Wanting to continue his legacy with knowledgeable, hard-working hands, he sold the business to three veterinarians out of Rensselaer, Indiana.

Drs. Dave Dixon, Chris Rumsey and Jake Hege were the perfect team to step in and keep operations running smoothly. Adding sire semen collections to their list of services is a seamless fit with their current business, StockVets, LLC, an ET veterinary practice. They will use their team approach to run an organized operation and their years of combined experience to produce top-quality service. With his outstanding reputation for quality samples, Bill will stay at Interglobe to run all semen collections, processing and freezing.

Expect a friendly face and superior service when you choose Interglobe Sire Service.

Your Genetic Connection. (Our Mission.)

As geneticists, we understand the importance of maximizing the desirable genetic traits found in premium animals. Our mission is to identify those traits, take collections from animals that carry them and then freeze or supply them to the owner for breeding purposes. Utilizing good genes can enhance animal growth, improve their health and give its body the ability to utilize more of nutrients they receive. The performance of your animals matters to us and we’ll do everything in our power to keep your animal line strong and consistent.

Partnering for the Future. (Our Vision.)

Our vision for the future is to create high performing animals, enhanced by controlled genetics, for many generations to come. We want to partner with breeders who value quality and advancement in technology. We see a future with fewer animal genetic disorders and better performing lineage, all carefully traced back to the original donor.

Our Promise.

We are committed to providing the most dependable, professional service in the industry. Your animal’s health, reproductive performance and care are our primary goals. Quality matters to us, and all collections we generate must pass rigorous testing to ensure that they meet our highs standards.
