Optical Dust Meters May Misestimate Dust Concentrations in Animal Barns

By Xufei Yang and Ryan Samuel et.al

 

Dust is a major air quality issue associated with livestock facilities. In an animal barn, dust particles can originate from feeds, feces, and beddings, and can reach a very high concentration when animals are active, ventilation is poor, and/or feeding systems are running. Dust also represents a potential safety and health risk factor for caretakers in barns. Dust particles at high concentrations, especially small particles, are harmful to the humans’ respiratory systems. Together with hazardous gases, dust exposure can cause chronic bronchitis, decreased lung functions, aggravated asthma, and other acute and chronic respiratory symptoms. Dust can also carry odorous chemicals and, thus, play a crucial role in transporting and magnifying odor downwind from animal facilities.

Video: Season 6, Episode 10: Defining Resiliency and the Research Driving Swine Health Forward

Genetic research and new technologies continue to influence the future of swine health and production efficiency. In this episode, we explore how research and technology are being used to support stronger, more resilient pigs, while also improving overall production outcomes. In this episode, we are joined by Dr. Jenelle Dunkelberger, geneticist with Topigs Norsvin, to discuss both routine and emerging strategies for improving piglet, pig, and sow livability. She outlines two primary approaches to enhancing resiliency: gene editing and traditional selective breeding. Continuing the resiliency conversation, we also hear from Dr. Lucina Galina, director of technical research projects at the Pig Improvement Company. She shares insights into ongoing gene-editing work focused on PRRS, detailing the pathway to success, regulatory and practical considerations, and the questions that still remain as the technology evolves. Together, these conversations provide a closer look at how research, genetics and innovation are shaping the future of swine health and livability.
