Phosphorus is required for both soft tissue and bone growth. Clinical signs of a deficiency include slowed growth for abnormal substance and unthrifty appearance. The calcium/phosphorus ratio should not be less than 1.2:1 for does and 2:1 for males. Grazing goats rarely develop a phosphorus deficiency due to their browsing phosphorus rich plants. Appropriate attention to calcium/phosphorus ratio is important to avoid promotion of urolithiasis. Additional information about phosphorus can be found at (Phosphorus).
