This research aims to find out the effect of giving a combination of probiotics and (Averrhoa bilimbi) powder extract on the egg white and yolk volume, yolk color, yolk cholesterol, eggshell thickness and eggshell colorof laying hens. The method used was experimental method with a Completely Randomized Design (CRD) of 4 treatments, each with 6 replications. The treatments consisted of P0 (-) = basal feed, P1 = 0.8% probiotics + 0.25%. Averrhoa bilimbi powder extract, P2 = 0.8% probiotics + 0.50% Averrhoa bilimbi powder extract and P3 = 0.8% probiotics + 0.75%. Averrhoa bilimbi powder extract. The variables measured in this research were egg quality including internal quality (egg white and yolk volume, yolk color and cholesterol) and external quality (eggshell thickness and color). The data were then analyzed by using ANOVA and continued with Duncan's Multiple Range Test. The results of this study were the addition of combination probiotics and Averrhoa bilimbi powder extract showed highly significant difference (P <0.01) on the egg white and yolk volume, yolk color, yolk cholesterol and eggshell thickness The conclusion of this study is that a combination of probiotics and Averrhoa bilimbi powder extract can be used as an alternative of antibiotic in feed.
