3.1. Growth performance
Effects of lactobacillus preparation on growth performance are shown in Table 2. No differences in initial BW were observed among the three groups. Pigs fed diets with 0.4 and 0.8 g/kg of L. brevis ZLB004 increased ADG, ADFI, and G:F (P=0.026, 0.031, and 0.022 respectively), and decreased diarrhea incidence (P=0.044), compared with the control group. No difference was observed in the performance between dietary treatments.
