Abstract: Effect of MDV-1 vaccines administered alone or with HVT on the development of the chicken embryo immune system
For every laying hen that is hatched, approximately one male counterpart also hatches. However, as roosters do not produce eggs, they are typically culled, or euthanized, at hatch. However, the culling of these day-old male chicks raises ethical concerns.

Producing the best feed for turkey production takes more than choosing a mash or pelleted version. It also includes maintaining quality from processing to the feeder.
In the highly automated world of poultry production, precision livestock farming (PLF) technology to monitor birds in real time can be used to improve their health, welfare and efficiency. But there are limitations to this technology.
Low crude-protein diets are a well-proven practice to reduce diet cost and minimize excess nitrogen and excreta, thereby benefiting profitability, health and welfare in broilers and swine. However, the laying-hen industry is far behind in understanding the interaction and requirement of lower amino acids.
Dust particles in poultry houses can exacerbate the spread of highly pathogenic avian influenza (HPAI), with the virus on dust particles remaining infectious for up to 17 hours. By the birds’ activity, it can easily be aerosolized into the environment and, by the ventilation system’s airflow, can be transmitted within the barn and from barn to barn.
