This study aims to analyze the effect of the used citronella essential oil in feed supplements on feed consumption and egg production of laying hens. The material used in this study was laying hens aged 30 weeks as much as (6 × 5) X 2 heads = 60 Brown strains. Feed ratio with ingredients Concentrate 35%, Corn 50%, Bran 15%. The treatment was given with varying dosage levels of citronella essential oil with 6 doses added to the premix. Premixes are added in the feed by 2%. The dosage of lemongrass oil is as follows: P0 = Premix + 0 % Citronella essential oil P1 = Premix + 1 % Citronella essential oil P2 = Premix + 1.5 % Citronella essential oil P3 = Premix + 2
% Citronella essential oil P4 = Premix + 2.5 % Citronella essential oil P5 = Premix
+ 3 % Citronella essential oil. This study was carried out for 16 days using 60 brown strain laying hens. The method used was a field experiment or experimental using a Complete Randomized Design with 6 treatments and 5 repeats, each test consisting of 2 chickens. The data were analyzed using the variance analysis method (ANAVA). Furthermore, if the results of the study have a real effect, continue with the Duncen test (Multiple Range Test) to determine the influence between the treatments tested. The results of the research were obtained by giving different levels of citronella essential oil to laying hens of the Isa Brown Strain layer phase aged 30 weeks. The highest feed consumption was in the P0 (0%) treatment at 113.08 gr/day/head. The lowest feed consumption was in treatment P5 (3%) which was not significantly different from treatments P3 (2%) and P4 (2.5%). The highest egg production was in treatment P2 (2.5%) with egg production of 87.4%. The lowest egg production was found in the constant P0 (0%) treatment – feed consumption. Providing citronella essential oil P2 (1.5%) can reduce feed consumption and increase egg production.
