Abstract
The utilization of dehydrated poultry waste (feces) by laying hens has been reported by Flegal and Zindel (1969). Inclusion of this material in the diet caused no significant differences in egg production, shell thickness, or weight of day-old eggs; however, significant differences in Haugh units were found.The purpose of the present study was to determine if dehydrated poultry waste (DPW) in the diet of laying hens had any effect on certain quality changes that occur in shell eggs during storage.PROCEDUREThe eggs used were from 32 Leghorn-type hens on each of four different diets. All of the birds were 10 months of age and had been on the experimental diets for three months. The diets used were (1) control, (2) control with 10% DPW, (3) control with 20% DPW, and (4) control with 30% DPW.One-day-old eggs were stored at room environment to accelerate the changes that occur.
