Abstract

In this study, we assessed the efficacy of a novel B. amyloliquefacience DS11 phytase (DS11 phytase) and that of a commercial Aspergillus ficcum phytase (AF phytase) through their bioavailabilities of phytin-posphorus and -calcium in the diet using cannulated pigs. For the purpose of evaluating the efficacy of the phytases in pigs, we determined phosphorous concentrations from serum and feces, in addition to ingesta obtained from the cannula at the terminal ileum. As results, phosphorus concentration was lower in feces from DS11 group and BASF group by 17% and 10%, and higher in serum from the respective groups by 34% and 20%, as compared to the control group. Both phytases are evaluated to enhance phosphorus availability to the great extent. Calcium concentration of feces were lower in DS11 group and BASF group by 31% and 10%, than that in the control. Calcium concentration of serum was higher in DS11 phytase group by 4% but lower in AF phyase group by 3%, then that in the control group.
