Therefore, their insufficient intake with food , poor digestibility lead to disease. osteodystrophy Osteodystrophy — chronic animal diseases characterized by disorders of calcium-phosphorus and vitamin exchange with primary bone lesions . Disorders of the absorption in the gastro — intestinal tract, developing as a result of errors in feeding or inflammation of the mucosa, can cause metabolic disorder , and hypocalcemia . Changes in bone manifested in the form of rickets , osteoporosis and ostemalyatsii . Insufficiency in the body lambs and kids and vitamin D disorders calcium and phosphorus metabolism cause profound disturbances processes of bone formation ( osteogenesis ) and stunting , namely rickets . In these bones predominates cartilage mass. I stopped growing animals, especially during lactation and pregnancy due to phosphorus — calcium , protein and carbohydrate and vitamins (D — and A — gipotavitaminoz ) insecurity , insufficient ultraviolet irradiation developing rickets or osteomalacia adults — chronic secondary tissue demineralization (yield salts).
Inconsistency diet structure level and nature of productivity , low biological usefulness of forages play a key role in the development of this disease. Older individuals usually marked osteoporosis — bone loss due to the predominance of the processes of absorption processes of osteogenesis . Characterized by bone fragility , poor healing of fractures. Osteodystrophy begin with perversion of appetite, hair loss , loss of productivity . Animals with the feeling worried Maklok , buttocks , metatarsals and pasterns .
