The combined effect of probiotics and prebiotics (PPS) in broiler’s digestive tract is effective in improving nutrient absorption and broilers health. Therefore, this study aimed to evaluate synbiotic effect of PPS in broilers diets on performance, blood lipid profiles, and pathogenic bacteria in intestines. Synbiotic comprised a combination of prebiotics Moringa oleifera leaves and probiotics yeast culture in a ratio of 1:1 (g/g). The results of in vitro analysis contained probiotics Saccharomyces spp. of 1.7 x109 cfu/g. Broilers used were 200-day-old chicks (DOC), divided randomly into 4 treatments with 5 replications, each consisting of 10 broilers. The control (treatment A) was given basic feed without the addition of PPS, while treatments B, C, and D were administered feed with PPS 0.2%, 0.4%, and 0.6% respectively. The results showed that supplementation of 0.2% PPS in feed significantly (P<0.05) increased feed efficiency by 3.77% and reduced cholesterol in serum by 24.79% compared to the control. Administration of 0.6% PPS significantly (P<0.05) reduced low-density lipoprotein (LDL) levels, while 0.2% PPS (P<0.05) reduced total cholesterol. Coliform and E.coli bacteria populations in broilers intestines had no significantly different effect (P>0.05) between treatments. This showed that the addition of 0.2% PPS to commercial rations could increase feed efficiency and reduce total cholesterol levels in broilers. However, the addition of 0.2-0.6% PPS to commercial feed did not have a significant impact on suppressing pathogenic bacteria in broilers intestines. Therefore, the types of prebiotics, probiotics, and their combination, as well as method of administration and concentration were recommended to be explored for further studies.
