Poultry diseases
When chickens are healthy they consume less feed and produce more quality eggs. They are less trouble to look after and less money is spent on medical costs. Poultry disease can spread rapidly among chickens because they are usually kept together in the chicken house. The chickens share the same feeders and drinkers, which can spread disease and infections rapidly from sick to healthy chickens. In intensive egg production systems, much focus is placed on the egg laying performance of the flock. Poultry diseases can negatively affect the health and performance of your flock. Important and common poultry diseases include necrotic enteritis, chronic respiratory diseases, gangrenous dermatitis, fowl cholera, and avian influenza.
Infectious diseases of poultry are mostly associated with severe economic losses. Many of these diseases once re-emerging or introduced into a geographic area can explode into an epidemic and may have a significant negative effect on international trade. Beside general control approaches like biosecurity, improvement of rearing management, monitoring, and vaccination several governmental measures on control of poultry diseases were adopted in European...
