What is the main nutritional effect of adding microbial phytase to a poultry diet?
Correct answer: D. Improved release of bound phosphorus
- A. Enhanced production of egg albumen
- B. Increased synthesis of vitamin D
- C. Reduced digestion of dietary starch
- D. Improved release of bound phosphorus
Explanation
Phytase breaks down phytate and releases phosphorus that would otherwise be poorly available to poultry. It may also improve the availability of some minerals, but it does not directly synthesize vitamin D or albumen.
