Topigs Insider: Producer Profile – Maple Grove Colony

Maple Grove Colony, established in 1981, is located in southwestern Manitoba and has a population of over 125 people. Like most Hutterite colonies, it has a diverse range of operations, farming 4,000 acres, managing 8,000 laying chickens, and running a 1,200-sow farrow-wean pig production unit.

The colony’s hog barn was originally built in 1984 as a 300-sow farrow-to-finish unit, later upgraded in 1998 to a 1,200-sow farrow-to-wean facility. In 2009-10, the original herd was depopulated and repopulated with GAP genetics. Since 2016, they have used Topigs Norsvin genetics, primarily TN70 gilts and TN Duroc sires, producing excellent offspring.

Currently, Maple Grove Colony has a farrowing rate of 91.3% and weans 12.76 piglets per litter, resulting in 31.21 pigs weaned per mated female per year. The colony’s production team is led by Michael David Waldner, with key team members Travis Waldner and Adam Waldner contributing significantly to the barn’s success.

Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger

Video: Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger


In this episode of The Swine it Podcast Show Canada, Dr. Jenelle Dunkelberger, geneticist at Topigs Norsvin, explains how genetics can improve disease resilience in pigs. She explores how resilience differs from resistance, the role of genetic variation, and how breeding strategies can enhance health and performance under disease pressure. Dr. Dunkelberger also covers practical applications and future implications for swine production. Listen now on all major platforms!

"Controlled experimental trials confirm that differences in mortality and performance under disease pressure are linked to genetic background, even when environmental conditions remain consistent."

Meet the guest: Dr. Jenelle Dunkelberger / jenelle-dunkelberger-9200ab86 is a geneticist at Topigs Norsvin, where she leads the Global Health and Behavior Research Platform. She earned her PhD from Iowa State University, focusing on host genetics and disease response in pigs. Her work centers on improving swine health and performance through genetic selection for resilience and behavior traits.
