The study was conducted to compare the production performance of Gramariya, Vanaraja, Haringhata Black and Rhode Island Red chickens in intensive condition. The study was undertaken in Murshidabad Krishi Vigyan Kendra of West Bengal state with respect to live body weight in different age, age at sexual maturity, average weight at first egg, average egg production up to 72 weeks of age and average egg weight at 40 weeks. The average body weight at onset of laying of Vanaraja birds was 1747.8 g which was highest than other breeds. Average age at sexual maturity ware 187, 195, 173 and 181 days in Gramapriya Vanaraja, Haringhata Black and Rhode Island Red breeds respectively. The average weight at first egg was highest (51.2 g) in Vanaraja but lowest (41.4 g) in Haringhata Black chicken whereas average weight of egg at 40 wks was highest (55.2 g) in Gramapriya but lowest (47.6 g) in Haringhata Black chicken. The egg production up to 72 wks of age was 153 nos in Gramapriya and 140, 136 and 129 nos in Vanaraja, Rhode Island Red and Haringhata Black birds respectively. Moreover, Gramapriya was genetically superior to Vanaraja, Rhode Island Red and Haringhata Black in terms of productive and reproductive parameters.
