Dr. Shawna Weimer
Animal welfare is oftentimes housed under the same umbrella as sustainability because improvements in both are viewed as progress towards the future. In other words, any improvement in animal welfare also improves the sustainability of production or potentially has less impact on the surrounding environment. However, the relationships between poultry production and welfare and the impact of production on the environment are complex and difficult to balance

Recognizing and Preventing Marek’s Disease in Small Flocks
Marek’s disease is one of the most widespread poultry diseases in the world. It is a highly contagious viral disease caused by a herpes virus called Alphaherpesvirinae. Marek’s disease occurs in chickens 3–4 weeks of age or older but is most common between 12 and 30 weeks of age. It can also infect quail and, rarely, turkeys. Female birds are infected more often than males. Once the virus is introduced into a chicken flock, infection spreads quickly from bird to bird and infected chickens continue to shed the virus, thus perpetuating a vicious cycle of infection. There is no effective treatment for the disease and infected birds never recover.
