Abstract

This study was conducted to evaluate the use of caraway seeds meal (CSM), as natural feed additives on growth performance and some blood parameters of common carp (2.457±0.057 g). Fish were divided into four groups fed on diets containing CSM in different levels; 0, 0.5, 1, 1.5% and the experiment extended for ten weeks. The CSM supplementation enhanced significantly fish growth over the control diet (P<0.05). Results showed that fish fed diets containing 1 % CSM had significantly higher growth performance (weight gain, gain % specific growth rate (SGR) and the lowest fish growth was obtained at control diet. Feed conversion ratio (FCR) decreased significantly in diet containing 1 % CSM (P<0.05). WBC levels decreased significantly in fish fed with dietary caraway compared with control treatment (P>0.05).There is also no significant difference between RBC, HCT and HGB in experimental groups (P>0.05). In addition, there were significant differences between biochemical parameters in fish fed with dietary caraway compared with control treatment (P<0.05). The highest levels of glucose and cholesterol were observed in control treatment and the highest level of total protein was observed in diet containing 1 % CSM. The results of this study show that addition of caraway to fish diet can promote growth and improve fish health.
