Effects of the addition of activated charcoal in feed on the morphology of intestinal villi of Giant Travelly juveniles (Caranx ignobilis)

This study aims to determine the effect of administration of different concentration of activated charcoal in feed on the morphology of intestinal villi of Giant Travelly juveniles (Caranx ignobilis). This research was conducted in February to March 2018 which took place at the Brackishwater Aquaculture Center (BPBAP) in Ujong Batee, Aceh, and a histology laboratory at the Faculty of Veterinary, Syiah Kuala University. The method used in this study was an experimental method using a completely randomized design (CRD) with five treatments and four replications. The treatment with different concentrations of active charcoal was treatment A (0%), B (1%), C (2%), D (3%), and E (4%). Results of the study found that treatment C showed the significant difference with other treatments (p <0.05) by morphological values of height (123.6 mu m), basal width (63.8 mu m), and apical width (42 mu m), respectively. Thus it can be concluded that the addition of activated charcoal in feed at 2% can improve the absorption of nutrition in the intestine.
