Effect of dietary supplementation with flying fish (exocoetidae) silage on the egg quality and duck performance

Abstract

This study aimed to evaluate the effect of dietary supplementation with flying fish silage on egg quality and duck performance. This study was design using a completely randomized design (CRD), 4 treatments of dietary supplementation (P0=7%, P1=8%, P2=9%, P3=10%) with 5 replications of laying duck. The observed variable of the egg quality was egg weight, egg yolk index (EYI), and Haugh unit (HU), and the duck performance were daily weight gain (DWG) and feed conversion ratio (FCR). The data were analyzed using ANOVA and followed by Duncan’s test. The results showed that the flying fish waste silage have no significant effect on egg quality and duck performance (P> 0.05). The EYI ranged from 0.790 to 0.816, HU ranged from 95.04 to 99.09, egg weight ranged from 63 to 66.92 g, DWG ranged from 3.34 to 5.42, and FCR ranged from 1.85 to 2.26. In conclusion, dietary supplementation with flying fish waste silage up to a level of 10% was not able to decrease egg quality and duck performance.
