Abstract
The objective of this work to explore the effect of feather colour on the carcass traits of Domyati ducks. A total of 169 one-day-old Domyati ducks were separated according to phenotypic colour into two groups, White feather (WF) and Brown feather (BF). The distribution ratios were 9% and 91% for WF, and BF, respectively. Carcass traits were taken at the marketing age, 16 ducks /each phenotype (8 male+ 8 female) were saluted. Non-edible meat parts were taken (blood- feather- legs- head- and viscera), edible meat parts (dressed carcass- liver- gizzard- heart), muscles (major – minor – thigh - drumstick), fats (Abdominal fat, gizzard fat – skin), also neck, wings and skeleton were measured.  The live body weight was significantly heavier for WF ducks compared to BF ducks. Also, the males recorded heavier body weight than females. The interaction was not significant. There is no significant effect for feather colour or sex on non-edible meat parts, muscles, fats, neck, wings and skeleton. However the BF ducks were significantly higher relative heart weight than WF ducks, the females were significantly higher relative heart weight compared to males, the interaction between feather colour and sex was not significant. In conclusion, there was no significant effect due to feather colour on studied carcass traits.
