Interaction of phytase RONOZYME ® P(L) and citric acid on the utilization of phosphorus by common carp (Cyprinus carpio)
Year: 2010
Type: article
Abstract: A feeding trial was conducted for 60 days to study the effects of the combination of microbial phytase and citric acidon phosphorus utilization in Cyprinus carpio fingerlings. Four diets designated as diet without phytase or inorganic phosphorussupplementation (T1), with 1.1% MSP (T2), with 0.55% MSP and phytase (T3) and with 0.55% MSP, phytase andcitric acid (T4). Four replicate groups of 20 fish were fed two times daily until satiation. Phosphorus digestibility and retentionwere measured as well as the fish growth performance. It is concluded from the results that the addition of microbial phytaseand citric acid enhances the availability of phosphorus from plant sources, improves bone mineralization, growth and feedefficiency. Combining a low dose of citric acid to the phytase significantly increased the positive effects of the enzyme.
