Data pertaining to a total of 251, 686, 184, 845 nos. of geese and 32 nos. of eggs were utilized to study physical characteristics; body weight and body measurements; productive and reproductive traits; mortality percentage and egg quality traits. Indigenous geese were found to be Cinnamon coloured with border plumage pattern and White coloured with solid plumage pattern. Bill colour was observed to be black, orange, yellow and admixture of black and orange. Shank and feet colour were observed to be orange and yellow. Least–squares means(LSM) for body weight at hatching, 1month, 2months, 3months, 4months, 6-8 months and 12 months and above age were found to be 0.087±0.001, 0.514±0.005, 1.699±0.043, 2.740±0.031, 3.030±0.022, 3.480±0.055 and 3.970±0.025 kg respectively.

LSM for age at first egg, annual egg production, clutch size and clutch interval was found to be 320.196±2.882 days, 19.886±0.306 nos., 9.897±0.143 nos. and 59.206±0.531 days. Two laying cycles in a year observed i.e. September to November and December to February and each laying cycle ranged from 12 days to 1 month. Average egg weight, shape index, shell weight, shell thickness, specific gravity, albumen index, Haugh unit and yolk index were found to be 115.445±2.320 g, 70.476±1.120, 16.756±0.282 g, 0.560±0.009 mm, 1.285±0.017, 0.075±0.001, 64.662±1.201 and 0.362±0.006.Yolk colour observed to be yellow and sometimes orange. Egg shell colour was observed white and sometime cloudy white. Geese found to be quite broody. Average fertility and hatchability % (TES) were found to be 87.11% and 80.53%. Average mortality % were recorded as 12.93, 9.52, 6.74 and 3.07 % for 0 to 1 week, 2 to 4 weeks, 4 to 20 weeks and 24 weeks and above age groups.EnglishThesis
