A feeding trial was conducted to assess the effect of super dosing of phytase in either normal or low
phosphorus or low calcium corn-soy based diets of broiler chicken. A total of 112 healthy, day-old, Cobb chicks
were distributed randomly to 4 treatments with 4 replicates each having 7 chicks. In the first two groups, normal
recommended P diet (0.45% available P during starter and 0.40% during finisher phase) was fed without
phytase supplementation (control) or supplemented with phytase (@ 2500 FTU; phytase unit/kg diet). The
third group was supplemented with phytase (@ 2500 FTU/kg diet) to a low P (0.31% available P during starter
and 0.15% during finisher phase) diet with normal Ca (1% Ca in diet). In the fourth group, it was similar to third
diet but with lower (0.8%) level of Ca. The inorganic P was not added to third and fourth groups during finisher
phase. The body weight gain and feed intake of chicks were similar during starter, finisher and overall phase.
The feed conversion ratio was lower in the third group during finisher phase as compared to other 3 groups,
however, it was similar when compared during overall phase. The bone morphology and mineralization was not
affected either by normal or lower P levels in diet supplemented with super dosing of phytase. The results
indicated that super dosing of phytase on low P and Ca diets were beneficial than the normal standard dose of
phytase in diet of broiler chicken.
