ABSTRACT
Meta-analysis of lactobacillus was built to evaluate the performance, histology and microbiota of lactobacillus on digestive tract of broilers. A database was built from previously published article from internet reporting lactobacillus as feed additives in broilers. Articles were strictly selected according to evaluation of title, abstract and parameter which used in the study. Database collected was statistically analyzed using the mixed model method with different study as random effect and level of lactobacillus as fixed effect using SAS program. Lactobacillus as potential feed additive had significant influence (p<0.05) to improve performance such as average daily gain (50.28 g), average feed intake (93.57 g) and feed conversion ratio (1.91) of broilers in ameliorate condition of digestive tract by decreasing the amount of Escherichia coli. Due to pathogen bacteria decrease, the histologic structures of digestive tract encounter improvement through minimizing damage of villus. In conclusion, lactobacillus supplementation in broilers increase performance due to improvement in the digestive tract and decrease in pathogenic bacteria with 5 x 10-7 cfu log-1 Lactobacillus population recommendation.
