To investigate the effects of using different levels of turmeric powder on ileal micro-biota in laying hens, one hundred and forty four, 22-weeks old White Leghorn hens were divided into 6 treatments with 4 replications and each replicate had 6 birds. Control group (T1) was fed maize-soybean meal based diet without antibiotic while birds in T2 group were fed basal diet with antibiotic. In treatment groups T3, T4, T5 and T6 basal diet was supplemented with turmeric powder @ , , , and 1% respectively. After 16 weeks of the experimental period one bird from each replicate was slaughtered and ileal contents were collected aseptically, weighed (1g each), transferred to sterile tubes and homogenized with sterile normal saline solution (1:1) and mixed on vortex. 10 fold serial dilutions of samples were made up to six dilutions and ml of each dilution was poured and spread uniformly on Mc Conkey Lactose Agar (MLA) for E. coli and MRS for Lactobacillus. | Effect of supplementing different levels of turmeric powder on gut microbiota in laying hens
