Performances and Egg Quality of Layer Fed Tapioca By-Products Fermented with Neurospora crassa

Abstract

An experiment was conducted to determine the effect of feeding tapioca byproducts fermented by Neurospora crassa on layer performances and egg quality. Two hundred layers were randomly allocated into 20 pens. This experiment was arranged in a completely randomized design with four dietary treatments: 0%, 10%, 20% and 30% tapioca by product fermented by N. crassa in the diets and fi ve replications. Variable measured were feed comsumption, egg production, feed conversion, egg cholesterol and egg yolk colour. Results of the experiment indicated that feed comsumption, egg production, feed conversion, egg cholesterol and egg yolk colour were affected (P<0.05) by using fermented tapioca by-product in the diets of layers. Results of Duncan multiple range test indicated that feed consumption, egg production, and egg yolk colour in D treatment (used 30% tapioca by-products fermented) were the highest compared to those other treatments, but the lowest on feed conversion and egg cholesterol. The conclusion of the experiment that tapioca by-products fermented by N. crassa can be used up to 30% in the diet of layer.
