  • Hog Slat features ONCE Dim-to-Blue technology

    When designing a lighting system, an implementation of light spectrum, intensity of light, and photoperiod, are all key characteristics to consider.  A recent Hog Slat blog post featured our color-shifting Dim-to-Blue® technology and explained the unique benefits this advanced lighting system can bring to promoting optimal broiler production. 


    The article explains:

    "What makes AgriShift® Dim-to-Blue® technology uniquely beneficial, is that it is designed to influence and direct certain processes, recreating the best possible environment for your animal. New developments in agriculture lighting can now provide a customized light spectrum, intensity and photoperiod control for broiler environments. The utilization of this advanced LED lighting in broiler facilities can bring performance benefits, resulting in increased broiler production and improved animal welfare."

  • MPF & VIV Trade one week!

    The week of March 13 was a busy one for us at ONCE® as we took part in two trade shows spanning in locations from Thailand, to our home state, Minnesota!  We had a booth at VIV Asia in Bangkok for the first time, and at the Midwest Poultry Federation Convention in Saint Paul. Get a glimpse of our trade show-filled week and to learn a little about the shows...



    VIV Asia hosts 900 exhibitors for all around the world. The scope of the show includes producers of swine, poultry, eggs, fish, and dairy, with suppliers from all segments of the feed to food chain. The show focuses on featuring global market leaders, regional, as well as national Asian players of growing importance. 


    Midwest Poultry Federation (MPF) Convention is the largest regional poultry show in the U.S. Participants include all segments of the poultry industry, including layers, broilers, turkey and organic/specialty poultry production. MPF is a nonprofit organization and all generated revenue from the convention goes to support poultry programs and their members.

    Our mini photo-biology lighting displays are always a hit (pictured above). 








    If you were at IPPE you may have recognized our "lego barn". We assembled this again at MPF, but it was configured a little differently!  



    In addition to the AgriShift TLUS®, we also featured our new AgriShift MLST®- a stringer specifically designed for any ONCE® ML fixture (pictured above).



    We featured our BioShift® UVC Germicidal Chamber at MPF, which  is designed to kill viruses in a 300-second sterilization process (pictured above). 



    Thanks for following along on our trade show filled week. We hope to see you next year either at VIV Europe or MPF!



  • IPPE 2017

    January 31-February 2, 2017, our team took part in IPPE, an expo hailed as the largest annual trade show for the poultry, meat and feed industries, in Atlanta, Georgia.


    Here's a recap of the expo and a look inside our lego-like booth...


    The journey of a trade show starts months ahead of the actual event with thinking about what the booth should look alike. Our brainstorming led us to try something new and build an entire booth out of Everblock plastic, modular blocks (shown below). 




    After experimenting with building the booth different ways in our warehouse, we were happy with the finished product, complete with benches, a conference room, a TV for viewing a promotional video, demonstrations of our facility lighting and mini barn lighting displays.

    New Lighting Product Improves Animal Welfare


    PLYMOUTH, MN (January 27, 2017) – ONCE, Inc. (ONCE®), an innovative animal-centric lighting company, will feature their newest lighting fixture designed to improve animal welfare at the 2017 International Production and Processing Expo (IPPE) in Atlanta, Georgia at the end of this month. Their brand new AgriShift® HL-UVA focuses on improving animal recognition and feeding cues through detection of ultraviolet spectrum wavelengths.


    The AgriShift® HL-UVA is a 3 Watt LED designed around the ecological importance that UV perception plays in the signaling of avian species. Poultry show a preference for artificial lighting environments with supplemental UVA. The implementation of UVA and AgriShift® technology enables recognition and feeding cues, which will help enhance production, lower mortality and boost overall immune response.

    "The fundamental mission behind our AgriShift® HL-UVA is to improve the welfare of your animal by providing an environmental stimulation that fits their needs," explains Jim Sulciner, President of ONCE®. "We could not think of a more opportune time to share the new product then at IPPE, surrounded by poultry industry leaders, researchers, and growers."


    The science behind the AgriShift® HL-UVA to utilize ultraviolet spectrum wavelengths, differentiates itself from any other agricultural facility lighting option on the market. To see a demonstration of the AgriShift® HL-UVA and learn how its implementation in poultry facilities can enhance animal welfare, stop by the ONCE® booth at IPPE located in hall C, space 2711.

    Circadian Eggs—An IPPE TECHTalk You Will Want to Attend


    PLYMOUTH, MN (January 12, 2017) – On Tuesday, January 31st at IPPE, ONCE Inc. (ONCE®) CEO, Zdenko Grajcar, will present on the benefits of optimized poultry lighting and how lighting entrains the circadian clocks in your animals.  As founder of the only photo-biology agricultural lighting company in the world, Grajcar has an established background in illumination science and as an avid researcher in light's effect on animals.


    There are three primary aspects of poultry lighting that Grajcar will be highlighting throughout his presentation. Optimizing these aspects in research studies and in production facilities has underscored the importance of the circadian clock in improving animals’ health and well-being.


    There is still room for improvement when it comes educating others on the significance of animal-centric lighting in the agricultural industry. “It is well-known that animals see light differently than humans,” describes Grajcar, “but there is a lot that people do not know, like how a molecular clock and rhythmic hormone release in poultry can help stimulate natural internal cycles, such as bone formation and sexual maturation. That is why a regular circadian clock is important. We create an environment for animals that cater to what they need,” he says.  “Our science stimulates reproduction in a cost-effective way.” 


    ONCE® is a revolutionary photo-biology Minnesota-based company working in a niche market to bring animal welfare options through facility lighting.               


    To hear from ONCE® founder and CEO on his industry leading research, come to his presentation at IPPE on January 31st at 11:00am in C1305, or stop by the ONCE IPPE booth, in hall C, space 2711 where many of their animal-centric lights will be on display.
