This study was conducted on two separate experiments in a factorial arrangement. In the 1st experiment stocking density and garlic supplementation on welfare status of Muscovy ducks was studied, 180 one -day -old Muscovy ducklings (108 female and 72 male) were housed into 12 symmetrical pens ( 2.5 m length, 2 m wide, 3 m high) classified into 6 treatments (2 replicate / treatment). [control (C) group] fed on basal diet with standard stocking density( 4 birds/m2) , (HS) group fed on basal diet with high stocking density (8 birds/m².), (SS+G₃₀₀) group fed on basal diet with 300 g. garlic powder / ton feed with standard stocking density, (HS+G₃₀₀) group fed on basal diet with 300 g. garlic powder / ton feed with high stocking density, (SS+G₆₀₀) group fed on basal diet with 600 g. garlic powder / ton feed with standard stocking density, (HS+G₆₀₀) group fed on basal diet with 600 g. garlic powder / ton feed with high stocking density. Results revealed that garlic supplementation (600 g. garlic powder / ton feed) reducing feed intake with better FCR and higher final body weight also improve carcass quality by reduce fat % and improve immune status of birds in standard stocking density and can effectively compensate the negative effects of the high stocking density in Muscovy ducks
