displayed in Table 4. There was no significant difference in BWG at the stage from 0 to 21 days (P40.05). During 22–35 days, the WSFS and FM groups were significantly higher in regard to BWG compared to the SBM group (Po0.05), but there was no significant difference with other groups. Throughout the whole trial, the WSFS group and the FM groups were significantly higher in BWG than was the SBM group (Po0.05). For the feed intake, during 0–21 days and the whole trial, the SBM group was significantly lower than the other groups (Po0.05), and during 22–35 days the result was WSFS4WFS4FM4 DSFS4SBM. For the feed conversion ratio, the SBM group was significantly better than the WSFS and DSFS groups during 0–21 days. There was no significant difference in mortality in all groups (P40.05).
