Using Lactobacillus plantarum and Tomi-Tomi Fruit Extract Synbiotics as a Natural Supplement in Broiler Chickens: Impact on Blood Profile, Gut Microbiota, and Performance

This research explores how synbiotics obtained from Tomi-Tomi fruit extract and Lactobacillus plantarum influence the growth rate, intestinal microbiome, and blood characteristics of broiler chickens.The synbiotics were prepared by incubating the Tomi-Tomi fruit extract with L. plantarum for 48 hours prior to experimentation.A group of 200 Lohmann broiler chicks was raised from day 0 until day 7, starting at an average weight of 1422.34g.On the eighth day, the chicks were distributed into five treatment categories randomly, with each category containing five replications: CONT (control diet without synbiotics), TFE0.25 (0.25% synbiotics), TFE0.50 (0.50% synbiotics), TFE0.75 (0.75% synbiotics), and TFE1.00 (1% synbiotics).During the duration of the experiment, marked advancements were observed in weight gain, consumption of feed, feed conversion efficiency, hemoglobin levels, and mean corpuscular volume (MCV) metrics (P<0.05).Furthermore, a significant drop in pH levels in both the ileum and cecum was evident, alongside a rise in lactic acid bacteria, and a significant decline (P<0.05) in coliform bacteria in these segments of the intestine.These findings suggest that the use of these synbiotics enhances feed efficiency, supports better physiological health, and suppresses harmful microbial growth in the digestive systems of broiler chickens.
