We are very much thankful for providing us and updating us on the OPTIMUM Nutrition in terms of Phosporus utility in poultry ration.
Your study is very elaborative but it will be complete if you will update us on the "impact of different water qualities on the efficay of Phytases"

2) Is water quality Viz. heavy metals, hardness, PH etc of water can change the efficay of Enzymes?
3) You have stated that "phytase derived from an E. coli strain released 0.10 to 0.20% P from corn-soybean meal diets at activity concentrations of 250 to 1,000 phytase units (FTU) per kilogram of complete feed (Applegate et al., 2003; Augspurger et al., 2003; 2004; 2007; Pillai et al., 2006)." Is this applicable in Indian Continent too?

Author deserve good praise for technically explaining the phenomenon of Phytase enzyme, especially effect of quantity of calcium in diet on threshold of phosphorus.
