The capacity of birds to maintain and increase the productivity, adapt to changing circumstances and resist diseases is vital. The Major Histocompatibility Complex (MHC) of vertebrates is a prime molecule responsible for disease resistance with extensive genetic polymorphism. The present investigation was undertaken to evaluate the polymorphism of the commercial broilers at the B-L?2 region by allele-specific PCR providing implications on association with production performance for the design of efficient programmes for its upgradation. Data were collected on body weight on first day, body weight at 6 weeks, feed consumed in 6 weeks and weight gain in 6 weeks. Feed conversion ratio (FCR) or feed efficiency and broiler performance efficiency factor (BPEF) were calculated from the data collected. The MHC haplotypes were found to be associated with these production traits. The B?? allele was significantly associated with high body weight, weight gain, low FCR and high BPEF
