Abstract
This study investigated the effect of dried food-waste diets (FW) fermented by Aspergillus oryzae (AEW), on egg Production and egg qualify in laying hens. One hundred sixty eight laying hens, 50 week old, ISA-Brown wtrain were randomly distributed into 7 treatments with 3 relpicates of 8 birds per replicate and fed with standards laying hen diet replaced with FW and AFW at die=rent level Basal Diet, 25, 10, $75\%$, respectively. There was a significant decrease in feed intake for FW $50\%$ diet and egg Production was statistically lower in all W diet treatments(p<0.05). Water consumption was increased as the replacement increased. Egg weight, egg shell thickness and strength were similar among treatments. However, egg yolk color and Haugh unit showed distinct differences when W were added to their diets(p<0.05). No difference was observed in egg yolk cholesterol. It seems that FW diet could decrease the egg Production, but would be able to improve egg Quality. From this results, AO seemed applicable to laying hen diet as supplements.
