Productive Performance and Economics of Broiler Chicken Fed Heat Treated Sheep Manure based Diets Supplemented with Enzyme
Asian Journal of Dairy and Food Research
Feed is the single largest input which accounts for 60-70% of the total cost of poultry production. Sheep manure is an unconventional feed relatively high in protein and energy levels and can be used in poultry diet to reduce the cost of production. Inclusion of exogenous enzymes will improve its nutritional value as it contains relatively high fibre and utilization by birds. The performance of broiler chicken fed with heat treated sheep manure (HSM) based diets supplement with or without
... was studied. Methods: 210 broiler chicks were randomly distributed to five groups viz. T1 (Control), T2: 5% HSM without enzyme, T3: 5% HSM with enzyme, T4: 10% HSM without enzyme and T5: 10% HSM with enzyme containing 42 chicks in each group having three replicates of 14 chicks each. Result: The chemical composition of HSM like Dry matter, Organic matter, Crude protein, Ether extract, Crude fibre, Total ash, NFE, Calcium and Phosphorus were estimated as 90.15±1.85, 71.88±1.62, 15.24±1.23, 4.22±0.86, 17.09±0.92, 28.12±1.32, 35.33±1.28, 1.15±0.08 and 0.48±0.03%. The ME (Kcal/kg) was 1565.33. The final body weight at 6 weeks of age was highest in T3 (1998.25±13.29g) and lowest in T4 (1949.22± 15.14 g). The cumulative feed conversion ratio ranged between 1.79 ± 0.083 in T1 to 1.83 ± 0.078 in T4. The cost of production per kg live weight was highest (Rs. 89.78) in T1 and lowest (Rs. 83.76) in T5 group. The benefit cost ratio was 1.14, 1.17, 1.19, 1.20 and 1.22 for T1, T2, T3, T4 and T5 groups respectively.
