Abstract
A feeding trial was conducted to determine the effect of microbial enzyme supplementation on layer diets. Forty eight (48) 42-week-old individually cage bobcock layers were randomly assigned to four dietary treatments (control, protease 1% amylase 0.4% and combination 1.4%) following a completely randomized design. Each treatment was replicated twelve times with an individually caged layers per replicate. Results showed that layers fed diet with protease had consistently but not significantly higher egg production in all periods compared to those fed other diets. The monthly and overall feed consumption of the layers did not significantly differ among treatments except on the third month. Layers fed diets with microbial protease had consistently but not significantly better monthly and overall feed efficiency compared to those fed other diets. The monthly and overall average egg shell thickness by layers fed control diet were consistently but not significantly thicker compared to those fed other diets. Layers fed diet with protease laid eggs with consistently lower monthly and overall yolk color score than those fed other diets. Enzyme supplementation of the layer diets decreased the IOFC.
