The only reciprocal cross produced was RIR X B. Thus, a total of eight different crossbreds were evolved for the present study. Simultaneously purebred population of K, AK, AP, NN, F and RIR were produced and maintained in three replicate as a control for comparison. The crossbreds were compared among themselves for body weight, weight gain, total feed consumption, FCR, and mortality, heterosis, economics in terms of EPEI and crossbreds were also compared for body weight and weight gain with purebreed control of each crossbredenPoultry ScienceStudyThesis
