Description A seel is a famous bird of Indian native chicken and is well known for its high stamina, majestic gait and dogged fighting qualities. In addition, it has plenty delicious flavored meat due to its biggest body size among the Indian native breeds of chickens accompanied by broader breast. About 13 varieties of Aseel are found in the country out of which Kagar and Peela are being maintained at the Central Avian Research Institute, Izatnagar. The average body weight of Aseel Peela at 0, 8, 20, 30 and 40 weeks of age for male and felnale chickens were 36.18±O.56 g, 35.89±O.53 g; 402.00±12.84 g, 385.37±11.20 g; 1550.38±34.72 g, 1479.63±43.66 g; 2246.25±57.54 g, 2097.96±71.51 g and 2627.62±71.94 g and 2449.07±103.72 g respectively. The male birds grew faster than female birds and both attained the maximum weight gain at 15th week of age. Seven nonlinear functions were fitted to average weekly body weights of male and female birds. Gompertz function was found to be the best function to describe the growth pattern of these chickens.
