A study was conducted on 400 purebred and 200 Crossbred chicken as Kadaknath, Aseel, Rhode Island Red, Brown Cornish, Kadaknath X Brown Cornish, Brown Cornish X Kadaknath, Rhode Island Red X Aseel and Aseel X Rhode Island Red, crosses for the comparison of their growth & reproductive performance. The growth trait were recorded at day old weight 2 – week body weight, 4 – week body weight, 6 – week body weight, 8 – week body weight and 10 – week body weight. The corresponding body weights were significantly higher in brown Cornish as 41.23 ± 0.69, 98.34 ± 2.58, 349.6± 33.45, 510.4 ± 12.97, 639.1 ± 12.34 and 1091 ± 18.11 gm. respectively. The conformation traits Keel bone length, Shank length and Breast angle were recorded and found significantly higher in Rhode Island Red as compare to other purebred and crossbred chicken. The reproductive traits like hatchability and fertility percent were observed higher in Rhode Island Red X Aseel cross and egg production was found higher in Rhode Island Red.
