Abrupt rises in mortality from highly pathogenic avian influenza (HPAI) can set off alarms at any poultry farm. Such was the case last year with an outbreak in a layer flock in Iowa.
There are many pests and pathogens to monitor on poultry farms, but bed bugs typically aren’t top of mind. Nevertheless, bed bug infestations have been resurfacing in US poultry farms. Does that present a health, performance or welfare problem for flocks?
Fowl cholera is a bacterial disease of poultry that commonly affects chickens around 15 weeks of age and older, but it can impact birds as young as 6 weeks, cautions Charlie Broussard, DVM, Merck Animal Health.
Even with the best flock-management and vaccination protocols, fowl cholera can occasionally find a crack in the system. Chronic, low-grade cholera problems can materialize, or occasional breaks in breeder flocks can suddenly appear.
Vaccination is key to managing fowl cholera in poultry. For a program to be successful, however, it’s critical to train vaccination crews to monitor vaccine “takes” or major cutaneous reactions within a flock — no easy task with today’s employee shortages and rotating vaccination crews.
As consumer demand for eggs from free-range chickens grows, a big question lingers: what is the best stocking density for chickens in free-range conditions?
The keynote address of the 2023 Poultry Science Association conference featured Yuval Cinnamon, PhD, an Israeli embryologist leading a team of scientists that developed the first layer flock that produces females only.
Smart ag technologies offer production and research benefits by providing real-time data on individual birds and at the flock level to optimize production, animal health and well-being, food safety and the environment.
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.
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.
Poultry scientists are taking a close look at moldy corn in an effort to better protect animal and human health.
University of Georgia scientists are honing machine learning approaches to track cage-free layers’ natural behaviors.
