Phytase as an alleviator of high-temperature stress in broilers fed adequate and low dietary calcium

This study aimed to investigate the effect of phytase and dietary Ca level on performance, phytate (inositol hexa-phosphate, IP6) concentration, and anti-oxidant enzyme activity in broilers exposed to cycling high environmental temperatures. A total of 2,970 day-old Cobb 400 male broilers were randomly allocated among 6 treatments, with 15 replicate pens, and 33 birds per pen. Corn-soy diets low in available phosphorus (avP, 0.15% matrix...
