This study was conducted with a total number of 135 day old broiler chicks were collected from the two breeding hatcheries in Bangladesh. The chicks were placed in an open poultry shed and exposed in winter season. There were three strains Cobb-500, Hubbard Classic and Arbor Acres, 45 of each strain divided 3 groups with 3 replications 15 broilers per pen. The feed intake at first and third weeks of age revealed that highly significant difference (P<0.001) in Cobb-500, Hubbard Classic and Arbor Acres in winter season. There was no significant difference (P>0.05) in live weight among the three broiler strains in winter season. In third weeks the significant difference (P<0.01) also observed body weight gain. The feed conversion ratio (FCR) of three broiler strains at first and third weeks of age in winter season were highly significant (P<0.001). There were no significant difference (P>0.05) of mortality. The dressing percentage differed highly significant (P<0.001) in winter at fourth weeks of age. It’s concluded that Hubbard Classic may perform the best in winter than Cobb-500 and Arbor Acres due to dressing yield. Arbor Acres of the later two strains may also be recommended for commercial production on the basis of FCR.
