Light impacts behavior in cage-free aviaries
Birds can move out of the reach of the workers’ hands in a multi-tier aviary system, so employees have to climb into the system to get to them. Researchers from Michigan State studied light...

Study: Day length during brooding did not impact broiler performance
Extended day length during the brooding period is thought to benefit broilers’ long-term performance and well-being. However, a University of Georgia study has re-evaluated that idea.

Hatchery tips for successful transition to NAE production
Preventing birds from getting sick is perhaps the biggest challenge encountered when transitioning from conventional to “no antibiotics ever” (NAE) production.

Hatcheries in NAE production systems can’t cut corners on cleaning, husbandry
Hatcheries providing chicks for no antibiotics ever (NAE) production need to be meticulous with cleanliness and good husbandry practices in order for the program to succeed.

Chick quality vital to no-antibiotics-ever success, consultant says
Focusing on chick quality from the moment eggs enter the incubator is critical to ensuring birds have the best chance of being healthy and productive in no-antibiotics-ever (NAE) systems.

Wet bulb reservoirs can be source of bacterial contamination for hatching eggs
Wet-bulb reservoirs in hatchery incubators should be included in the bacterial-monitoring program to ensure they aren’t the source of egg-shell contamination.
-
Ensuring chick quality in NAE production
The increase in 7-day chick mortality that has come along with the elimination of antibiotics requires a focus on containing bacteria that start in the layer house.

Four areas of hatchery management to help achieve better biosecurity
Diligent attention to four areas of hatchery management — egg-pack quality, incubation, sanitation and in ovo vaccination — can go a long way.

Hatchery hygiene helps limit broiler E. coli mortality risk
Disinfecting eggs and improving overall hygiene in the hatchery could dramatically reduce the risk of mortality linked to E. coli infections, scientists say.
-
Dirty chick boxes can be source of Salmonella at hatcheries
Dirty chick boxes at hatcheries can be a source of Salmonella, but the risk was still lower than expected in a study conducted at one US hatchery.
-
Lameness in poultry can start in the hatchery
Lameness in poultry is often associated with bird weight, bacterial infections or the condition of the litter, but it actually begins much earlier in the bird’s life — often in the hatchery.

Halting in ovo vaccination not a good option for managing hatchery bacteria
Higher 7-day mortality from bacterial infections in the hatchery is no reason to stop in ovo vaccination for Marek’s and other diseases, according to a consulting poultry veterinarian.

E. coli becoming more common with rise in ‘no antibiotics ever’ programs
With the removal of antibiotics in the hatchery in “no antibiotics ever” (NAE) programs, the bacterium Escherichia coli is becoming more of a problem at many broiler complexes.
