treatment receiving the phytobiotic, including 5.8% larger average shrimp
size at harvest and 12% better feed conversion compared to the control
group. The addition of the phytobiotic reduced drastically the variability
of production results among ponds fed the same feed (average coefficient
of variation between ponds for the 6 production parameters: control 18%
versus SANACORE group 10%; Table 7).
