Abstract
An experiment was conducted to investigate the effects of feeding fermented food waste on the egg production and egg qualities in laying hens. A lot of 30 commercial layer(ISA Brown) at the age 58 weeks were placed in individual of 80% commercial feed and 20% fermented food waste(C80%+F20%), a mixture of 50% commercial feed and 50% fermented food waste (C50%+F50%), and a mixture of 20% commercial feed and 80% fermented food waste (C20%+F80%). Daily measurements were made on feed intake, egg production rate, egg weight, yolk color, Haugh unit, shell color during the experimental period. At the end of the experiment, body weight change and egg cholesterol contents were determined. The results indicate that up to 50% of basal diet could be supplied by fermented food waste with little depression in feed intake and efficiency in egg production (p＜0.01). Egg weight, egg shell thickness and Haugh units were not significant different between the treatments and the control. Egg color quality improved with increasing the proportion of the fermented food waste in the diet.
