Economic evaluation of omega-3 fatty acid enriched duck egg production by feeding diet supplemented with Lemuru fish oil

This study aimed to evaluate the economic impact of omega-3 fatty acid enriched duck egg production by feeding diet supplemented with Lemuru fish oil. Materials used in this study was 72 local ducks at 40 weeks of age, which equally divided into 12 flocks. The ducks received 1 of 3 experimental diets, either basal diet without Lemuru fish oil supplementation (control) or basal diet supplemented with 10 or 20 g Lemuru fish oil/kg. Results showed that experimental diets did not give significant effect (p>0.05) on total feed intake and egg production, but significantly affected (p<0.05) total omega-3 content of duck egg. Supplementation of Lemuru fish oil either at 10 or 20 g/kg could increase (p<0.05) total omega-3 fatty acid content compared to control. The use of Lemuru fish oil slighly decreased total feed cost and total cost, and increased total return, net return and R/C ratio. This study provide evident that the use of Lemuru fish oil could be used as nutritional strategies to produce omega-3 fatty acid enriched duck egg. The use of such supplement also could improve economic benefit. It is suggested to use 20 g fish oil/kg diet to achieve optimum profitability of omega-3 fatty acid enriched duck egg production.
