Press Release: ONCE Director of Biological R&D is Speaker at IA Egg Symposium

PLYMOUTH, MN (September 18, 2018) – Dr. Aaron Stephan, Director of Biological R&D at Once Inc. (ONCE), will present Basics of Lighting in Lay Farms at the Iowa Egg Industry Symposium next month.

The single-day symposium will touch on an assortment of topics pertaining to layer management including genetics, vaccination, management and flock biosecurity. Stephan will be joined by five additional industry experts and attendees traveling from all over the Midwest to learn more about this year’s theme, “Optimizing egg quality and egg production.”

Stephan, who presented a similar educational talk at the International Production & Processing Expo’s TECHTalk in January explains, “This is a great opportunity to educate growers about the value of lighting for managing layers. The core of ONCE technology has and continues to be optimizing lighting spectra and schedules, differentiating the pullet from the layer stage. Combining this with strategic luminaire placement, we’ve found that lighting systems can dramatically improve flock performance.”

Taking place on November 13th in the Scheman Building at the Iowa State Center in Ames, Iowa, this egg symposium is a good face-to-face networking opportunity to meet with colleagues, customers and friends of the layer industry. To learn more or register visit:
