Abstract: The purpose of this experiment was to evaluate the production performance of hybrid broiler chickens from two-way crossbreeding between ♂Choi x ♀Luong Phuong and ♂Luong Phuong x ♀Choi chickens. The experiment included 4 treatments (T), namely T1: pure Luong Phuong (LP), T2: pure Choi (C), T3: hybrid broiler chickens of (♂C x ♀LP) and T4: hybrid broiler chickens of (♂LP x ♀C). Each experiment had 70 unsexed one-day old chickens, replicated 5 times, and ended when the chickens were 98 days old. T1 and T2 were arranged to compare the result of hybrid chickens with their parents. Chickens of all treatments were fed ad libitum with the same complete mixed feed, and with the same care and feeding regime. Results showed that hybrid broiler chickens of T3 and T4 had livability rate of 95.14%, and 93.71% at 98 days of age, body weight reaching 2070 and 1969 g/bird, the FCR of 3.03 and 3.12 kg/kg weight gain, respectively. Whereas the heterosis of the FCR trait of T3 chickens was less than the average of their parents (negative value). If the FCR trait has a negative value, it is good and expected. Hybrid broiler chickens of T3 and T4 had similar slaughter results and meat quality, except for meat color. The production performance of hybrid broiler chickens was less than that of Luong Phuong chickens, but was much better than Choi chickens, in which hybrid broiler chickens of T3 (♂C x ♀LP) were more improved than T4 (♂LP x ♀C).
