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.

As like the human beings, livestock are unable to express their problems so depending upon the clinical signs shown by them and history told by the owner, we have to diagnose the preliminary causes. But for final...

Introduction Cellulitis is an acute and diffuse suppurative inflamation, affecting all subcutaneous tissues and in certain instances the muscular tissue as well. It is frequently associated to abscess formation. In birds, cellulitis causes discoloration and thickening of the skin, hence, it is also known as an inflamatory process, or necrotic dermatitis (Norton, 1997). In recent years, the...

Vaccines are used to prevent or reduce problems that can occur when a poultry flock is exposed to field disease organisms. Vaccinations should be thought of as insurance. Like insurance, there is a price to be paid for protection against a potential threat. Costs include price of the vaccine, time spent designing the vaccination schedule and administering the vaccines, and losses due to vaccine reactions from the live-type vaccines...

When a bird is vaccinated, or exposed to a viral or bacterial infection, a complex biological mechanism is set in motion which normally results in the elevation of the bird's specific defenses against the disease in question. Sometimes this process also raises non-specifically its defenses against other infections. The immune response is generated by a complex system of specialized cells, the lymphocytes. All vertebrates have such a system but those of birds and...

Gastrointestinal diseases pose a serious threat to industrial poultry breeding. Infections are caused by proliferation of naturally occurring intestinal microorganisms and their subsequent translocation to other organs and tissues of the birds. The consequences are a deterioration of feed conversion ratio, an increase in mortality and finally a reduction in productivity. According to the World Health Organization (WHO) this leads to a...
