Supplementation of Synbiotic Content of Moringa oleifera Extract and Lactobacillus to Improve Growth Performance in Starter Phase Diet of Broiler Chicken

Prebiotics are substrates that can be used to increase the growth of probiotics. Oligosaccharides, polysaccharides and galacto-oligosaccharides have important functions as prebiotics to improve intestinal health through increased growth of beneficial bacteria. Synbiotics are combinations of probiotic bacteria and prebiotic food ingredients. This study examined the synbiotic effects of Moringa oleifera extract as prebiotic and probiotic incorporating Lactobacillus fermentum and Lactobacillus plantarum on the growth performance starter phase of broiler chickens. The dietary treatments comprised of the starter basal diet control and supplemented with 1% prebiotic + 1% probiotic, 2% prebiotic + 1% probiotic and 1% prebiotic + 2% probiotic, 2% prebiotic + 2% probiotic, respectively. The results showed that there is a significant difference (p<0.05) between control and treatment. Furthermore, the supplementation of 1% prebiotic + 2% probiotic produces the highest body weight values. Meanwhile, the lowest feed conversion ratio (FCR) and the highest feed efficiency were supplemented with 1% prebiotic + 2% probiotic, 2% prebiotic + 2% probiotic, 1% prebiotic + 1% probiotic, which was similar to the supplementation with 2% prebiotic + 1% probiotic, while the lowest feed consumption was found in 2% prebiotic + 2% probiotic. Therefore, based on the results of this study, it can be concluded that supplementation of 1% to 2% prebiotic and 1% to 2% probiotic has the ability to enhance the production performance of starter phase broilers compared to the control.
