Abstract
This study aims to evaluate the use of a combination of phytobiotics and probiotics on external egg quality in laying ducks. The number of ducks used in this study was 120 which were divided into 4 treatments and 5 replications, each replication consisting of 5 ducks. The treatments were T1: control, T2: 0.25% combination, T2: 0.5% combination and T3: 0.75% combination. The external egg quality variables observed were egg weight, egg length, egg width and egg index. Observations on variables were carried out once a week during four weeks,every repetation using 2 eggs. The data obtained were analyzed statistically using a completely randomized design ANOVA. If the results of the show significantly different then continue with the DMRT test. Based on the results, it shows that the different levels of the combination phytobiotics and probiotics showed significantly different results (p<0.05) on egg weight in the 1st and 4th weeks, egg length in the 1st week, egg width in the 4th week and egg index in the 1st week. week 1. The addition of 0.5% combination of phytobiotics and probiotics can improve the external quality of duck eggs.
