This disease is a disease of puppies. It is mainly a non-inflammatory disease caused by vitamin D deficiency and calcium and phosphorus metabolism disorders. Pathological characteristics are insufficient calcification of osteoblasts, persistent cartilage hypertrophy and temporary calcification insufficiency of epiphyseals. Clinical characteristics are digestive disorders, heterophilia, lameness and bone deformation. Puppies aged 1 to 3 months are prone to this disease. If this symptom occurs in adult dogs, it is called chondropathy.
【Cause】
The food is lacking in vitamin D or sunlight. There is a lack of calcium, phosphorus minerals or calcium, phosphorus ratio in food, especially phosphorus deficiency.
Long-term chronic digestive tract dysfunction, such as diarrhea, affects the absorption function of the intestinal mucosa.
Early symptoms include decreased appetite, indigestion, cross-birth, inactive mentality, prolonged teething, and matte hair. As the course of the disease progresses, developmental stagnation, weight loss, severe lameness, swollen epiphysis, long bone deformation with weight bearing, O-shaped legs or X-shaped legs. In severe cases, you can lie down and not get up, and the whole body will be deformed and painful, and even paralyzed. Osteoporosis, using puncture needles is very easy to puncture and fractures are prone to occur. Fractures often occur when jumping on their own, playing or with a slight external force. X-ray, visible.
The bone ends of long bones are irregular and ossification is incomplete.
[Symptoms] According to age and the conditions of vitamin D, calcium and phosphorus in the feeding food, characteristics such as growth retardation, heterophilia, prolonged teething period and skeletal deformation are generally not difficult to diagnose. If necessary, X-ray examination can be used to find the characteristics of reduced bone density and "wool-like" at the ends of long bones.
【Treatment】
@Really sunbathing.
@Vitamin D Therapy: Vitamin D, 33~57Y units/kg weight, injection once every 3~5 days. Or take vitamin D orally, 50,000 units/kg body weight, 1 time/day, for 7 consecutive days.
@, calcium gluconate injection 0.1~0.2 g/kg body weight, intravenous drip, 1 time/day or 1 time the next day.
@Calcium supplements should be maintained frequently in food, such as bone meal and calcium powder.
