How does visual perception of laying hens affect resource usage in cage-free housing?

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.

Researchers evaluate effects of heat stress in turkey poults

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.

Why does mortality from blackhead differ in chickens and turkeys?

Chongxiao (Sean) Chen, DVM, PhD, assistant professor/extension specialist with University of Georgia Department of Poultry Science, presented his research on blackhead disease in poultry during the 2023 IPPE.

Broiler diets low in crude protein may get boost from individual nonessential amino acid supplementation

A new study led by poultry scientists at the University of Hohenheim suggests it is possible to reduce crude protein in broiler diets while still encouraging bird growth.

Poultry researchers: There’s no safe amount of moldy corn for laying hens

Poultry scientists are taking a close look at moldy corn in an effort to better protect animal and human health.

Biosecurity, detection and response remain pillars of HPAI control in US

Biosecurity remains the best tool for combating highly pathogenic avian influenza (HPAI) H5 viruses in the US, according to a government expert.

Wood heat exchangers promote drier litter, better footpad quality

External wood heat exchangers have a positive effect on broiler production compared to radiant propane brooders, which are generally used to heat US poultry houses.

Increasing carbon dioxide levels in incubators cuts woody breast incidence

Injecting CO2 into incubators can cut the incidence of woody breast — a muscle condition posing a challenge for the broiler industry.

Ultrasonic water meters highlight management issues affecting young birds

Ultrasonic water meters have a modest cost, but they’re an effective tool to tackle a variety of issues early in the life of birds in production.

‘Machine vision’ technology shows promise for monitoring bird behaviors, health

University of Georgia scientists are honing machine learning approaches to track cage-free layers’ natural behaviors.

Study sheds new light on how avian reovirus affects gut microbiome

Infection with avian reovirus leads to reduced bacterial diversity in birds’ guts — a possible explanation for how disease caused by the pathogen is aggravated by intestinal disturbance.
