Efficiency of digestion and metabolism is reflected in waste products (faeces and urine). Phosphorus and nitrogen outputs are critical to environmental pollution.
Look for a highly effective phytase to reduce both phosphorus and nitrogen outputs to the environment. Carbohydrases (e.g. xylanase and amylase) and proteases, in particular, can further enhance nitrogen utilisation, reducing nitrogen outputs in waste products (faeces and urine).
