Evaluation of the Use Flour Kenikir (Cosmos caudatus Kunth) as an Organic Feed Additive on External Eggs Quality of Laying Hens

This research purpose to evaluate the effect of using flour (stem+leaves) on kenikir plants which is potential as a feed additive to the external quality of laying hens. This research has been conducted in Bacem Village, Sutojayan District, Kab. Blitar. This research uses an experimental method with design Complete Random Design (CRD) consists of 4 X 6 replications. Treatment P0 = Basal Feed + 0% flour (stem + leaf) kenikir, P1 = Basal feed + 0.25% flour (stem + leaf) Kenikir, P2 = Basal feed + 0.50% flour (stem + leaf) kenikir, P3 = Basal feed + 0.75% flour (stem + leaves) kenikir. The data were analyzed by ANOVA and continued by Duncan's Multiple Range Test (DMRT). The parameters observed are egg shell weight, proportion of eggshell and thick eggshell. The results of research showed that the gift of flour (stem + leaves) of kenikir plants as feed additives give significantly different effect (P <0.01) on egg shell weight, proportion of eggshell and not significantly different effect (P>0,05) on thick eggshell. The conclusion of this research gift flour (stem + leaves) of kenikir on level 0,75% can give effect the external quality eggs of laying hens
