Effect of jamblang leaf in drinking water on physical quality, lactic acid bacteria population and intestinal villi histology of broiler chickens

Abstract

This research was conducted aiming to find alternative antibiotics using local plants that are rich in antioxidants. The antioxidant content in plants is used as a feed additive and as an alternative to antibiotics, so that livestock products are safe from antibiotic residues. Jamblang leaf is one of the potential typical plants in Aceh which is expected to be used as an alternative to antibiotics in broiler cultivation. The study used 4 treatments of jamblang extract given into drinking water. P0 used drinking water without jamblang extract, P1 used 0.25 g/L drinking water, P2 used 0.5 g/L drinking water, P3 used 1 g/L drinking water. The study used a completely randomized design (CRD) with 4 treatments and each treatment was repeated 3 times with a total of 5 chickens per replication. The parameters measured were the physical quality of the intestinal villi (height of the intestinal villi, lumen thickness and number of glands), the population of lactic acid bacteria (LAB) in the digestive tract, and the histological condition of the intestinal villi of broiler chickens. Data were analyzed using analysis of variance. The results showed that the treatment had no significant effect (P>0.05) on the physical quality of the intestinal villi, but the treatment significantly (P<0.05) decreased the LAB population in the P2 treatment. The condition of the intestinal villi due to the treatment still stood upright compared to the control. In conclusion, jamblang extract given into drinking water has not been able to improve the physical appearance of the intestinal villi and tends to reduce the LAB population in the intestinal tract.
