Abstract

Transferrin polymorphisms and growth rate up to 12 weeks of age were observed in RIR, crossbreds and native chickens. TfBB genotype was observed in all types of bird. TfBC occurred only in crossbred and native chickens. Frequency of TfB was the highest in all types. Mean body weights at 8- and 12- weeks of age were the highest in RIR (292 37.77 and 612 75.69 g respectively) and the lowest in natives for TfBC (180 11.54 and 308 4.94 g respectively). The difference in 12 week body weight of crossbreds between TfBB and TfBC was found to be significant (p<0.05). The results indicate that crossbreds (TfBB) may be grown effectively upto 12 weeks of age under Bangladesh conditions.
