297 DIETARY SUPPLEMENTATION WITH TURMERIC POWDER: IMPACT ON FEED CONVERSION RATIO IN CAGE-CULTURED COMMON CARP (CYPRINUS CARPIO) (Додавање на куркума во исхраната: влијание врз конверзијата на храна кај кафезно одгледуван крап (Cyprinus carpio))

This study investigated the effect of dietary supplementation with turmeric powder (Curcuma longa L.) on the feed conversion ratio (FCR) of common carp (Cyprinus carpio) reared in an intensive cage system. The experiment lasted 92 days and included two groups: K5 (feed supplemented with 2% turmeric powder per kg) and K8 (control group, commercial feed without additives). FCR was monitored across three control measurements. The results showed that carp fed with the turmeric-supplemented diet (K5) achieved a consistently lower mean FCR compared to the control group (K8), indicating improved feed utilization efficiency. The biological trend clearly demonstrated the beneficial impact of turmeric on feed conversion. These findings suggest that turmeric acts as an effective natural phytogenic additive capable of enhancing feed efficiency and potential factor sustainable carp production.
