title: Effects of different levels of hatchery wastes on the performance, carcass and tibia ash and some blood parameters in broiler chicks.
abstract: This experiment was conducted to evaluate the effects of different levels of Hatchery Wastes (HW) on performance, tibia ash, blood calcium and phosphorus concentrations in broiler chickens. Birds were fed a corn-soybean meal diet for 7 days. The experimental treatments included a corn soybean meal diet and 3 other treatments containing 1.5, 3.0 and 4.5% HW. five replicate groups of 15 Ross 308 broiler chicks were allocated to each dietary treatment. Data were analyzed in a completely randomized design. Results indicated that there were no significant differences in weight gains among different dietary treatments. Feed intake in the 4.5% treatment was significantly higher (p < 0.05) and 3% treatment had lower feed intake than the other treatments. The results indicated that feed conversion in the 3% HW treatment was lower in most of the period (p > 0.05). Results of carcass analysis showed no significant differences between treatments. Also, there were no significant differences between blood calcium and phosphorous among treatments. The 4.5 and 3.0% hatchery wastes treatments had the highest tibia ash (p < 0.05). Based on the result of this experiment, the utilization of hatchery wastes as much as 3% can increase tibia strength without having adverse effect on broilers performance.
