Web Summary

This article discusses trials conducted with channel catfish on phytase applications. Phytase concentration of 250 FTUs/kg diet applied post-pelleting improves phosphorus utilization and can effectively replace the dicalcium phosphate supplement in catfish diets without affecting growth, feed efficiency, or bone P deposition. It is possible to replace all supplementary phosphorus in catfish feeds when phytase is applied, provided that the feeds are formulated with ingredients high in phosphorus.
