Abstract
This study aims to determine the Curcuma xanthorrhiza Roxb encapsulated as a feed additive and its use on the performance of broiler intestinal characteristics. The method used was a field experiment using a Completely Randomised Design (CRD), which consisted of 6 treatments and 4 replicates, namely- (P0-) negative control (commercial feed), (P1+) positive control (0.1% antibiotic), P2 (C. xanthorrhiza encapsulation 0.25%), P3 (C. xanthorrhiza encapsulation 0.50%), P4 (C. xanthorrhiza encapsulation 0.75%), and P5 (C. xanthorrhiza encapsulation 1%). The results showed that Curcuma xanthorrhiza encapsulated as a feed additive in the P3 treatment could increase the height of villi, the number of villi, the surface area of intestinal villi, and decrease the pH value of broiler intestines
The addition of C. xanthorrhiza encapsulated to broiler feed can have a very significant effect (P<0.01) on the height of the villi, the number of villi, the surface area of the villi and viscosity, and a significant effect (P<0.05) on the pH of the intestine, and gives non significant effect (P>0.05) on the depth of intestinal crypts. The conclusion, the addition of C. xanthorrhiza encapsulated to broiler feed at the level of 0.5% is recommended as an alternative feed additive to replace the use of synthetic antibiotics in order to obtain an optimal performance of broiler intestinal characteristics.
