Battery cage trial was conducted to determine the effects of Effective Microorganisms (EM) on production performance, carcass characteristics and nutritive qualities of Muscovy Ducks. A Randomized Complete Block Design utilized 72 male and 72 female Muscovy Ducks was used. The four treatments were control, EM added in drinking water, EM added in feed and EM added in both drinking water and feed. It was found in this study that EM supplementation in drinking water and for in feed had no significant effect on production performance but had significant effect on breast percentage, ash content in breast meat and polyunsaturated fatty acid content in duck oil. Result of chemical analysis also showed that EM supplementation apparently increased protein content of breast meat. Sexes were found to influence significantly on growth, feed consumed and feed conversion of Muscovy Ducks aged 4 weeks up to 16 weeks. For carcass characteristics, sexes had significant effect on eviscerated weight percent, liver percent, gizzard percent, breast percent and abdominal fat percent.
