Effect of Natural and Hydroponic Barley Plant and Sprout on the Common Carp (Cyprinus carpio) Growth Performances

摘要

This study was designed to investigate the effect of natural, sprout powder and hydroponic planting of Barley onsome growth parameters of common carp Cyprinus carpio L. The trail was conducted for 56 days and for thispurpose 175 fingerlings common carp, mean initial weight of 34.71 g were acclimated to laboratory conditions andfed with control pellets (30%crude protein) prior to the feeding trials for 21 days. Seven experimental diets wereused and the control as 0% (T1), Natural planting 2.5 (T2) and 5 gm/kg diet (T3), Hydroponic Planting 2.5 (T4) and 5gm/kg diet (T5), Barley sprout powder 2.5 (T6) and 5 gm/kg diet (T7). According to the results no significantdifferences observed in mean initial weight this was done in way to avoid differences attributed to fish initial weight,T4 (Barley sprout powder 2.5 g/kg diet) was significantly higher in each daily and relative growth rate, but thespecific growth rate both T4 and T7 were significantly higher than other treatments. No significant differencesobserved in Food Conversion Ratio and Protein Efficiency Ratio but T4 (Barley sprout powder 2.5 g/kg diet), T6(Natural planting 2.5 gm/kg diet) and T7 (Natural planting 5 gm/kg diet) differ significantly in Food Efficiency Ratio.As general conclusion the adding of germinated barley enhance common carp performance in any way ofgermination.
