VACCINE AND HOW TO VACCINATE YOUR BIRDS

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and keep a record of it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

RICKET AND CAGE LAYERS FATIGUE

Rickets and cage layer fatigue are nutritional diseases of chickens, turkeys and ducks that results in soft bones. Often the leg bones become bowed and hamper the bird’s ability to stand and walk. The term ‘rickets’ is generally used to describe the condition in young poultry, while ‘osteomalacia’ is often the term used for the disease in adult birds. Caged layer fatigue is a related condition observed in caged laying hens, usually around peak egg production, that may also be associated with osteoporosis, a condition causing brittle bones as a result of reduced bone density.
