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.

Video: Methionine Requirements for Lactating Sows - Cierra Kozole


In this episode of The Swine Nutrition Blackbelt Podcast, Cierra Kozole, PhD candidate in Swine Nutrition at the University of Guelph, explains how methionine supports lactating sows beyond milk protein synthesis. She discusses updated requirement estimates, source comparisons, methylation demand, and why modern sow genetics may require more precise amino acid strategies. Listen now on all major platforms!

"Methionine supports protein synthesis while also serving critical functions through methylation pathways that influence multiple biological processes."

Meet the guest: Cierra Kozole / cierra-kozole-772b64253 is a PhD candidate in Swine Nutrition at the University of Guelph in Canada. Her doctoral research focuses on refining estimates of methionine requirements for primiparous lactating sows, including evaluating methionine sources, nutrient partitioning, methylation reactions, and the links among amino acid supply, milk production, and sow protein retention.
