The objective of the present study was to determine the synergistic effect of lauric acid and probiotic on the nutrient retention, total bacterial count, gut pH and cost economics of broiler chicken. A total of 250-day-old male broiler chicks were randomly distributed into five dietary treatment groups each having ten replicates with five chicks in each and were raised for a period of 42 days. Diets contained T1- control diet, T2- 0.05% antibiotic (AB), T3- 0.05% lauric acid (LA), T4- 0.1% probiotic in the form of Bacillus subtilis PB6 (BS), and T5-0.05% lauric acid +0.1% probiotic. The results revealed no significant effect on dry matter (DM) and crude protein (CP) retention but energy retention was significantly (P<0.05) higher with LA, BS and AB compared to control. The total bacterial count was significantly (P<0.05) reduced in LA followed by LA+BS compared to control, AB and BS. The pH in proventriculus and gizzard was significantly (P<0.05) reduced in LA and BS compared to AB and control. The pH in duodenum was reduced in LA compared to other treatments with no significant effect in the ileal pH. LA in combination with BS or alone in broiler diets was economically better (P<0.05) compared to AB and control birds. Therefore, it can be concluded that supplementation of lauric acid (0.05%) + probiotic (0.1%) combination has resulted in gut acidification, reduced total bacterial load, improved nutrient absorption and is economically better. Thus, could be safely included as an alternative to antibiotic growth promoter in broilers.
