<div style="text-align: justify;">Background: In present scenario cost of common feed ingredients like maize and soybean are in rising trends due to less availability. &nbsp;Thus, the feed industry is forced to search the way to combat the feed cost. Rice Distillers Dried Grains with Solubles, is one of the best alternative source of feed ingredient. It has good source of energy, protein, vitamins and minerals. &nbsp;Presently, rice as subtract for bioethanol production is increasing due to its relative lower price, higher production and easy availability leads to increased availability of co-product rice distillers dried grains with solubles. In present study Nutrisigma&reg; has been used. &lsquo;Nutrisigma&reg;&rsquo;is rice distillers dried grains with solubles produced by IFB Agro Industries limited, Kolkata. In consideration of the above fact, the present experiment was designed to study the effects of &ldquo;Nutrisigma&reg;&rdquo; on productive performance of Khaki Campbell ducks. &nbsp; Methods: A total of nine hundred female Khaki Campbell ducks of the same genetic background and of comparable body weight at 72 wks of age, were randomly assigned into 3 dietary treatments that is Control (C), Treatment 1 (T1) and Treatment 2 (T2) each with 3 replicates of 100 ducks and they were studied for 60 days. All the experimental ducks were fed 120gm/duck/day concentrate mixture. Treatment group received (T1 group @ 3 gm/duck/day and T2 group @ 5 gm/duck/day) &lsquo;Nutrisigma&reg;&rsquo; in addition to concentrate mixture. Result: In our experiment egg production (%), fertile egg production per day, fertility%, hatchable egg weight (gm) and hatchability% were increased significantly (p&lt;0.05) in treated groups compared with control group. Better economic efficiency was observed in T1 group compared to T2 and control groups. In conclusion, Nutrisigma &reg; with concentrate mixture could be used economically up to 5gm/head/day (T2) without any harmful effect on&nbsp;productive performance, however, the use of 3 gm/head/day (T1) is more economical than 5 gm/head/day.</div>
