Abstract

This study was conducted to investigate the effect of molasses kombucha on performance, intestinal morphology and intestinal microbial population on 320 Ross male broiler chickens in a completely randomized design in 5 treatments and 4 replicate with 16 chickens in each replicate, in the starter (1-10 days old), growth (11-24), the final (25-42) and whole period (1-42). Experimental treatments include drinking water containing: 1) tap water with no kombucha, 2) 0.015 and 0.003 kombucha, respectively, during the starter and growth period, 3) 0.015, 0.003 kombucha and 0.003 three days a week, respectively during the starter, growth and finisher period 4) 0.015 Kombucha during starter and 0.003 kombucha three days a week during growth and finisher period 5) 0.015 Kombucha during starter and growth period and 0.003 kombucha three days a week during finisher. All experimental treatments had a higher body weight gain than the control group (P < 0.05). During the starter and whole periods, except for treatment 2, addition of molasses kombucha significantly improved the feed conversion ratio (P<0.05). There was a significant increase in the villus surface area of the treatments compared to the control group (P<0.05). Molasses kombucha caused a significant increase in the Lactobacillus population and decreased the total coliforms in the cecum environment (P<0.05). In conclusion, 0.015 Kombucha during starter and growth period and 0.003 kombucha three days a week during finisher can improve the performance of broiler chickens.
