Iowa State participates in US Precision Livestock Farming Conference

Several faculty and graduate students from Iowa State Department of Animal Science at the US Precision Livestock Farming Conference (USPLF2023) in Knoxville, Tennessee and NC1211 multistate meeting in Knoxville, Tennessee May 21-24.

Juan Steibel, Will Taylor and James Koltes presented research findings as seminars at the meeting, which you can find here.

Juan Steibel, James Koltes, Rich Gates and the late Ken Stalder were meeting program organizers involved in putting on the meeting over the past year. Both James and Juan served as session chairs at the meeting as well.  Juan also provided leadership in the overall meeting organization and selection committee for USPLF2025, which will be held in Nebraska. Prior to the formal conference, Juan organized a meeting as the current chair of the NC1211 multistate group (Precision Management of Animals for Improved Care, Health, and Welfare of Livestock and Poultry), which held it’s annual meeting jointly with this conference.  

The meeting was exciting as the field of PLF is moving rapidly.  Many applications of image, sound and wearable sensor data in research were presented as well as exciting new farm applications of PLF in several species.  Sensor measures are rapidly developing as phenotypes for application in overall management, genetics, welfare and animal health.
