Abstract: Lactobaccillus were isolated from cecal contents of laying hens fed in cage and identified by Gram staining, strain morphous observing and biochemistry fermentation. The results showed that 15 strains were G+. Selected by antibacterial activity and identified by biochemistry fermentation with different sugar, 7 lactic acid bacteria were identified, and they were Lactobacillus viridescens, Lactobacillus helveticus, Lactobacillus plantarum, Deshi Lactobacillus, Leuconostoc mesenteroides dextran, Leuconostoc mesenteroides and Leuconostoc mesenteroides subsp cremoris, respectively.

Key words: laying hens; lactic acid bacteria; cecum; isolation and identification
