Effect of Corn Fermented with Saccharomyces cerevisiae on Growth Performance, Carcass Traits, and Serum Blood Parameters of Ducks

This study evaluated the effects of corn fermented with Saccharomyces cerevisiae (S. cerevisiae) in the diet on growth performance, carcass traits and serum blood profiles of ducks.The study was conducted using a completely randomized design with four treatments and four replications, involving different levels of replacement of corn with fermented corn (FC) in the diet (0, 15, 30, and 45%), designated as FC1, FC2, FC3, and FC4, respectively.A total of 96 ducks were allotted to the treatments.The birds were provided feed and water ad libitum.The results showed that the addition of fermented corn had a positive effect on body weight, daily weight gain and it also improved the feed intake and feed conversion ratio in the FC4.In terms of carcass characteristics, the weights of the breast and thighs in FC4 increased significantly, with the maximum breast weight reaching 277.8 g (P0.05).Moreover, blood biochemical indicators did not exhibit considerable changes (P>0.05).It can be concluded that the use of fermented corn in the diet contributes to improving growth performance in ducks without any negative effects on their health.
