Morphology, morphometry and certain egg quality traits of indigenous ducks of North Eastern region of India

Abstract

Different morphological and morphometric traits were studied in the indigenous ducks of Northeastern India under field condition namely Pati and Nageswari ducks of Assam, Tripura local ducks of Tripura and Manipur local ducks of Manipur. The recorded body weights (kilogram) at 20 weeks age were 1.040 and 0.990; 1.233 and 1.210; 1.020 and 0.980 and 1.757 and 1.689 in male and female Pati, Nageswari, Tripura Local and Manipur local ducks respectively. The mean length (centimeter) for shank, girth, keel and bill were recorded as 5.675, 31.022, 11.03 and 5.444 in Pati, 6.401, 31.124, 16.132 and 5.89 in Nageswari, 5.640, 30.971, 10.97 and 5.230 in Tripura local and 6.141, 34.000, 12.312 and 6.000 in Manipur local respectively. The average of different egg quality traits namely egg weight, shape index, air cell height, shell thickness, albumen index, yolk index, haugh unit score, yolk colour and yolk weight were observed. The average of egg weight (gram) were 58.03, 61.04, 57.84 and 66.33 for Pati, Nageswari, Tripura local and Manipur local ducks respectively.
