^*Aftera series of 1:10 dilution, cecal digesta samples were incubated at 37°C for 24 h on Brilliant Green Sulfa Agar (BGS) supplemented with 200 µg/ml nalidixic acid.

^#Individual trial was analyzed by SAS GLIMMIX procedure and Dunnett’s method was used for adjustment of multiple comparisons with the positive control group as the control. The negative control group was not included for multiple comparison analysis. SAS GLIMMIX procedure was used for analysis of the two trials simultaneously (combination of the two trials) with trial as a fixed effect. NA, not applicable; P value for trial effect <0.01.
