A total of 300 one month age old Kadaknath chicks were randomly divided into three treatment groups (T1, T2 and T3) of 100 chicks each. The T1, T2 and T3 group of birds were reared under cage system, deep litter system and mud floor system respectively. At one month age the average weight of T1, T2 and T3 group birds were 0.263±0.012 kg, 0.248±0.017 kg and 0.250±0.01 kg respectively. Standard management practices were practiced in all systems of rearing. All groups were fed with 40 % grower mash, 40% broken rice and 20 % finely chopped Co4 fodder grass. At the end of 16th week of age, live body weight of birds of T1, T2 and T3 groups were taken and then they were humanely slaughtered at ILFC slaughter hall. The following data on live weight, carcass weight and dressing percentage of T1, T2, and T3 group were recorded as 1.51±0.01 kg, 1.20±0.052 kg, 1.32±0.052 kg and 1.04±0.01kg, 0.79±0.01 kg, 0.88±0.031 kg and 69.02±0.13%, 66.14±0.25%, 67.32±0.13% respectively. The results revealed that the live weight, slaughter weight and dressing percentage of birds reared under cage system was significantly higher compared to that reared under deep litter and mud floor system.EnglishOther
