Abstract :

The aim of this study was to Investigate the antioxidant effects of cinnamon powderas a growth additive in the diet of Green Terror Andinoacara rivulatus on growthperformance, feed conversion ratio and survival rate. For this purpose, a total of 180Green Terror fries (mean initial weight of 1.00± 0.5 g) were divided into fivetreatments (each treatment with three replicates and each replicate with 12 fry).Experimental treatments were fed with four diets with concentrations of 0.1, 0.2, 0.3and 1 percent of cinnamon powder compared to the control group (without cinnamonpowder) for 98 days. Growth parameters were calculated including weight gain(WG), length gain (LG), specific growth rate (SGR), feed conversion ratio (FCR),condition factor (CF), and survival rate (SR) in each treatment. The Data wereanalyzed in after normal distribution test by using one way ANOVA and Kruskal-Wallis tests. According to the research results, different levels of cinnamon powderdid not show significant statistical differences (P<0.05). But, there were significantdifferences in final weight gain and length gain between fish fed with one percent ofcinnamon powder compared with the control group (p>0.05). The fry fed with dietscontaining 1% of cinnamon powder with final mean weight (10.78±0.07 g) showedthe most weight gain compared to control group with a mean weight gain.
