Growth ability of two duck lines V72, V77 and commercial hybrid VSM7
This study evaluates the meat productivity of two specialized meat duck lines, V72, V77, and the commercial hybrid VSM7. The experiment was designed using a completely randomized design (CRD), with each group consisting of 50 ducks (25 males and 25 females), repeated 3 times. Results after 49 days of rearing showed that the survival rates of all three groups were high, with the V72 and V77 lines achieving 97.33% and the commercial hybrid VSM7 reaching 98.00%. The highest body weight was observed in the V72 males (3741.18 g), followed by the VSM7 hybrid (3656.03 g), and the lowest in the V77 females (3368.29 g). The feed conversion ratios (FCR) for the V72 males, V77 females, and VSM7 hybrid were 2.33, 2.56, and 2.36 kg/kg body weight, respectively. Carcass analysis showed the highest carcass yield in the VSM7 hybrid (70.92%), followed by the V72 line (70.79%), and the lowest in the V77 line (69.99%). The thigh and breast meat ratios for the V72, V77, and VSM7 hybrid were 17.11% and 22.48%; 16.28% and 21.99%; 16.84% and 22.28%, respectively. The production index and economic index for the V72, V77, and VSM7 hybrid were 319.03 and 11.41; 261.50 and 8.52; 310.05 and 10.96, respectively
