Effect of adding licorice glycyrrhiza glabra roots powder on growth parameters and blood indicators of common Carp Cyprinus carpio L.

Abstract EN

This study aims to use licorice roots powder as animal food additive to support rations of common carp and improve growth parameters and blood indicators.

It was carried out for period of 60 days from (6/4/2017 to 4/6/2017) at nutrition laboratory/Fish Department.

50 fish of common carp Cyprinus carpio L.

with average weight (15 ± 0.66) gm were distributed to five treatments (T1, T2, T3, T4, and T5-as control) with two replications, fed on 0.2, 0.4, 0.6, 0.8, and 0% of Licorice Glycyrrhiza glabra respectively as additive food in fish rations.

Results showed that T4 (0.8% ) was exceeded significantly (P≤ 0.05) all other treatments in all growth parameters (Weight Gain, Specific Growth Rate and Food Conversion Efficiency) and blood indicators measurement (RBCs, WBCs, PCV, and Hb) also results revealed that all licorice treatments were excelled control treatment in both parameters and indicators (Growth and Blood).

In conclusion, the addition of 0.8% licorice roots powder achieved higher values of growth parameters and blood indicators measurement than the other concentrations.
