Morphological Characteristics of Pati Duck
- Email email@example.com
Methods: The study was conducted at Govt. Duck and Poultry Farm, Joysagar, Sivasagar district of Assam. Ducklings were hatched at the Hatchery unit present at the farm. Eggs were been collected from different farmer’s house where they reared ducks in the backyard systems. Ducklings born were been studied for the different morphological characteristics and their body weight were been measured in weekly interval. All ducks received adlibitum feed from day one onwards.
Result: Pati ducks were divided into five major groups based on their body coat colour. They are Whitish light brown, White, Blackish brown, Black and white and Khaki coloured. The different body measurement shows the male to be superior to the females in different parameters with different coat colour. The major colour pattern of bill, shank and feet was found to be yellow, whereas skin was mostly white in colour and plumage colour pattern found to be white, black and brown in different parts of the body.
Pati duck is extensively reared by the rural woman of Assam in backyard system and proved as a major source of livelihood as well as machinery for women empowerment and an effective tool for socio-economic up liftmen of rural people. It is one of the most important domesticated species of poultry next to chicken primarily reared for table egg production in India. Though, many phenotypic studies have been done on Pati duck, but scanty information are found in morphology and morphometrical characteristics. Hence, the present study is undertaken to identify the morphology characteristics of Pati duck.
MATERIALS AND METHODS
This was taken with a sensitive top loading scale of 5000 g capacity at day-old and at weekly intervals.
This was measured as the distance between the tip of the bill and rear end of the beak.
This was measured over the point of nostrils.
This was measured as the distance between rear end of bill and condyle occipital.
This was measured as the distance between the first and last cervical vertebrae.
This was measured between the anterior and the posterior border of the breast-bone crest.
It was measured as length of the body from the base of the bill to the tail near the uropygial oil gland.
This was measured as the distance from the shoulder joint to the extremity of the terminal phalangx.
This was measured as the circumference of the body under
the wing through the anterior border of the breast bone crest and the central thoracic vertebrae.
This is the distance from the hock joint to the extremity of the digitus pedis.
This is the distance from the knee joint to the hock joint.
All linear body parameters were taken with a tailor tape in centimeters. The birds were closely observed for distribution of colour pattern in Bill, Eye and Eyelid. Plumage colour pattern in all part of the body (Head, Neck, Wing, Back, Tail, Thigh and Breast) were identified and documented by visual observation for the present study.
RESULTS AND DISCUSSION
The matured Pati ducks after attaining an age of 8 weeks and above show different body coat colour. So Pati ducks were divided into five major groups based on their body coat colour (Mahanta et al., 2001) and mentioned in Fig 1 the five groups are coded as A, B, C, D and E based on their colour pattern.
Pati duck started laying eggs at an age of 26 weeks. There after they continuously kept on laying eggs more or less in all day (Phookan, et al 2018). The average weight of the eggs laid is mentioned above. The hatching percentages of the Pati duck eggs were on an average above 55%. The matured Pati ducks were then studied for different body parameters as mentioned in the Table 2.
Table 3 and Table 4 shows the colour pattern of the different groups of ducks shows different contour in respect of their body coat colour. Predominantly the bill colour is found to be yellow to orange in all the groups irrespective of male and female except in the case of khaki coloured female the bill colour is somewhat brown in colour. The feet colours in case of all the ducks and drakes are orange in colour. A typical greenish colour marking of the head region is seen in male of the Blackish brown group, whereas the marking is absent in case of the females.
