Dustbathing environment may influence immune status of laying hens
Newer systems for laying hens provide more space for them to express natural behaviors such as scratching, pecking and dustbathing, which could have some biological benefits.

There’s a new egg on the block in the US — the carbon-neutral egg from Kipster Farm. It’s the result of a different approach to egg farming that started in 2017, when Kipster, a Dutch egg producer, introduced the world’s first carbon-neutral egg to the Netherlands.
USDA’s Agricultural Marketing Service estimates that two-thirds of laying hens in the US will need to be in cage-free production by 2026 to meet the projected demand, but the practice requires considerable planning by producers.
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.
There has always been a myth perpetuated that chicken litter contains weed seed, but litter is simply poultry manure and bedding; neither should contain many seeds.
Poultry scientists are working to better understand the impacts of particulate matter (PM) on bird health and production.
As most producers know, poultry performance can suffer during periods of high temperature. Modern poultry housing is designed to maintain environmental temperatures within an optimal range, but how does the temperature of individual birds impact their weight gain?

Preventing disease transmission between flocks is a major goal of the poultry industry. One threat to bird health is the protozoan Histomonas meleagridis, which causes a disease called histomoniasis.
After a decade studying how to reduce losses from necrotic enteritis and gangrenous dermatitis on broiler farms, Don Ritter, DVM, an independent consultant who heads Poultry Business Solutions, Norfolk, Virginia, believes the industry is finally making progress against these two clostridial diseases.
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.
