The correct spelling of the word "Perosis" may be confusing, but it is pronounced as "pəˈrōsəs". This term refers to a bone disorder that affects poultry, causing their legs to become weak and brittle. The word "Perosis" is derived from the Greek word "peri," meaning "around or about," and "osis," which refers to "disease or condition." Therefore, "Perosis" describes a condition that affects the bones, specifically those around the leg joint, of poultry.
Perosis is a medical condition characterized by deformities and abnormalities in the legs and feet of birds, primarily poultry, and specifically affects fast-growing, meat-producing breeds of chickens. Also known as slipped tendon, it is a musculoskeletal disorder caused by a deficiency in nutrients, especially manganese, Vitamin D, and calcium, during the bird's growth phase.
Birds affected by perosis exhibit various symptoms such as a crooked or twisted tibia bone, enlargement of the hock joint, bowed legs, and shortened tendons. The affected bird may exhibit difficulty in walking or standing due to weak or damaged leg muscles and joints, resulting in lameness. In severe cases, the condition can lead to the complete inability to walk or support body weight.
Perosis primarily affects young birds that are being raised for meat production, typically during the first few weeks of their lives. It is mainly associated with imbalanced diets, poor nutrition, poor husbandry practices, rapid growth rates, and genetic factors. Prevention and treatment strategies include providing balanced and fortified poultry diets, supplementation of important nutrients, such as manganese and Vitamin D, and proper management practices.
Overall, perosis is a debilitating condition that negatively impacts the welfare and productivity of poultry birds, and effective prevention and management strategies are crucial for the successful rearing of healthy and productive birds.
The word "perosis" has its roots in Latin and Greek. It originates from the Greek word "perōsis", which means "a limping or partial paralysis". The term was later adapted into Latin as "perosis", belonging to the same meaning. In the early 20th century, "perosis" was adopted as a medical term to describe a condition called "perosis in poultry", which involves a degenerative disease affecting the joints and bones of young birds.
