dc.description.abstractA study was conducted during 2006-07 with Muscovy duck population in different studied areas. The phenotypic colour of head showed seven colour patterns with dominated Black colour. The throat colour was observed as White, Brown White and Black White etc. The Pink White black, Pink Black and alternate Pink Black colours bills were recorded. The highest frequency (79%) of Pink colour skin was observed. The colour of shank pattern of Muscovy ducks showed four definite colour patterns at all the places under study. The present investigation with regard to eye colour showed only two colour patterns of the eye in case of Muscovy duck. All the studied Muscovy population had well developed knobs. The females were devoid of knobs. The mean length of neck and breast width were measured as 3.78±0.08 and 5.18±0.05 inches respectively. The average mean length of keel bone was recorded as 5.47±0.06 inches. The overall mean length of thigh was observed as 5.15±0.4 inches. The overall egg weight was found to be 62.66 g. Anjora flock has highest mean egg weight (66.61g) followed by 60.26 g in Jagdalpur farm. The highest egg length was recorded in Anjora farm followed by Jagdalpur farm with overall mean length 5.98 cm. The overall mean width of eggs was observed as 3.93 cm. The overall mean shape index of egg was recorded as 66.32 per cent. There are four different colours namely pale white, reddish white, dusty white and bluish white colours were observed. However, pale white colours were found to be more in numbers. Similarly premonsoon season experienced with highest laying followed by monsoon, summer and winter. Regarding system of rearing, 72.5 per cent farmers reared Muscovy ducks under free range system whereas 27.5 per cent farmers reared under semi-intensive ducks. Most of the laying was completed either in early morning or in night hours. Maximum body weight gain (765.41g) was observed for 60-75 days time with an average gain per day of 51.02 g. Birds consumed about 2.53 kg feed during these periods. The feed conversion efficiency was found to be 1:2.85 in the entire study period. Muscovy ducks were apparently found to be more resistant to diseases.en_US
