1, calcium and phosphorus content in feed is insufficient. Chickens need more calcium and phosphorus for growth and egg production. If supplementation is insufficient, calcium and phosphorus deficiency are prone to occur.
2. The imbalance of calcium and phosphorus in the feed. The imbalance of calcium and phosphorus will affect the absorption of the two elements. The ratio of calcium to phosphorus in the diet of chicks and laying hens should be between 1:1 and 4:1.
3, vitamin D deficiency. Vitamin D plays an important role in the absorption and metabolism of calcium and phosphorus. If vitamin D deficiency occurs, calcium and phosphorus deficiency can occur.
4, other factors. Excessive protein in the diet, or excessive fat and phytate, as well as excessively high ambient temperatures, lack of exercise, and lack of sunlight, can all be pathogenic factors. Diseases and physiological conditions also affect the metabolism of calcium and phosphorus, and the need to cause deficiency.
