Influence of Feeding Dehydrated Poultry Waste on Broiler Growth, and Meat Flavor, and Composition

Effects of feeding three levels (9.6, 19.1, and 38.2%) of dehydrated poultry waste (DPW) to broilers were studied. The performance of the group receiving 38.2% DPW was the poorest as evidenced by lower average live weight, lower average eviscerated weight, and poorer feed conversion. Flavor differences were studied using the triangle taste test. Analysis of responses revealed that panel members could not accurately detect flavor differences between the two extreme treatments (those receiving 0% and 38.2% DPW). Carcass composition changes were studied by analyses of dark meat for protein, ether extract, calcium, phosphorus, and TBA value. No significant differences in composition were noted among treatments from these analyses. Under conditions of this study, dehydrated poultry waste had no noticeable effect on carcass quality, though growth was somewhat depressed at the highest level. Thus DPW may be fed to broilers at a level below 20% without serious consequences.
