Abstract

 This experiment was conducted to evaluate the effects of using RICE BRAN, combo multi-enzyme and probiotic (protexin) in diet on PERFORMANCE, egg traits, biochemical parameters and blood cells of commercial LAYING HENS. This experiment carried out using 384 Hi-line (W36) LAYING HENS in a completely randomized design as factorial (2´2´2) arrangement with two levels of RICE BRAN (0 and 10%), two levels of combo multi-enzyme (0 and 0.05%) and two levels of protexin (0 and 0.005%) in 8 treatments, 4 replicates and 12 birds per replicate for 12 weeks (65-76 weeks). Using 10% RICE BRAN in diets improved the egg weight, egg production percentage and egg mass, feed conversion ratio, egg yolk color index and blood HDL of LAYING HENS (P<0.05), whereas did not have any significant effects on the amounts of feed intake and immune cells (P>0.05). Combo multi-enzyme in diets did not have any significant effects on PERFORMANCE, EGG QUALITY TRAITS and blood parameters of LAYING HENS (P>0.05). Using protexin in LAYING HENS diets without having any significant effects on EGG QUALITY TRAITS and blood parameters (P>0.05), improved the feed conversion ratio (P<0.05). In using RICE BRAN with combo multi-enzyme and protexin, PERFORMANCE, egg traits and blood HDL improved (P<0.05), whereas did have any significant effects on the amounts of feed intake and immune cells (P>0.05). The overall results indicated that in laying using 10% RICE BRAN with 0.05% of combo multi-enzyme and 0.005% of probiotic can improve the PERFORMANCE, egg traits and blood HDL.
