Consequences of calcium interactions with phytate and phytase for poultry and pigs

Examining Ca interactions with dietary phytate and phytase, particularly exogenous, microbial phytases, and their consequences for poultry and pigs finds that high dietary Ca levels may disrupt protein–phytate complex formation by interacting with both protein and protein even at acidic pH levels, thereby influencing the outcomes ofphytase amino acid digestibility assays.
