NCSU: ESPs may improve indoor air quality for cage-free layers
Bird welfare is improved in cage-free layer systems compared to cage systems, but indoor air quality suffers in a cage-free environment due to higher bird activity.

Updated research supported by the US Poultry & Egg Association quantifying the US poultry industry’s on-farm antibiotic use shows further improvements in antibiotic stewardship and commitment to disease prevention within poultry production.
Multi-stage egg-incubation systems are challenging to manage. And too often, attempts to keep late-stage embryos from overheating create situations where early-stage embryos are at sub-optimal temperatures during critical developmental periods.
Hatchery sanitation is a continual issue in commercial poultry and has become a focus since the removal of antibiotics in production, according to Brian Jordan, PhD, associate professor at the University of Georgia.
In this age of “no antibiotics ever” farming, the re-emerging necrotic enteritis (NE) disease caused by Clostridium perfringens poses a major economically important health concern in poultry, particularly in broiler flocks, says Ravi Kulkarni, BVSc, assistant professor at North Carolina State University.
Light intensity has been shown to affect the activity of birds, but most studies have focused on constant light intensities to determine their effect on welfare.
Colibacillosis resulting from E. coli is arguably one of the major causes of morbidity, mortality and carcass loss to the poultry production industry worldwide, putting at risk one of the cheapest and most valuable sources of protein.
Pathogenic Enterococcus cecorum continues to plague the broiler industry, causing mortality from pericarditis and sepsis early in the growing period and lameness and paralysis late in the growing period.
Campylobacter jejuni is a leading cause of bacterial-derived gastroenteritis in the US, due to its ability to asymptomatically reside within the intestinal tracts of poultry.
Nikki Shariat, PhD, assistant professor at the University of Georgia, presented her research on profiling Salmonella serotypes through broiler processing at the 2023 IPPE.
Geneticists have been trying, with little success, to determine and select egg layer strains that will perform well in cage-free production systems because there are numerous unknown factors which influence a hens’ performance.
Many turkey poults may experience poor starting performance for reasons that are not well understood. Turkey flocks may even suffer mortalities up to 3% within the first three weeks of life.
