When evaluating MDCP, the most critical factor is the Phosphorus (P) content, which typically ranges between 21% and 22%, and the Calcium (Ca) content, usually around 15% to 18%. Ensure the P solubility in 2% citric acid is above 95%, as this determines the biological availability for the poultry. Additionally, the Fluorine (F) content must be strictly controlled below 0.18% to prevent toxicity, and Heavy Metals (Lead/Arsenic) must comply with international feed safety standards (e.g., Pb < 30ppm, As < 20ppm).
