The Table 7 showed that the THC in Florfenicol group was significant
higher than that in other treatment groups (P < 0.05) and
there were no significant differences among other treatment
groups (P > 0.05). The phagocytic rate in the control group was
significantly lower than that in other treatment groups (P < 0.05)
and there were no significant differences among PS2, PS3 and
Florfenicol groups (P > 0.05). The LSZ in control group was significant
lower than that in other treatment groups (P < 0.05). The SOD
in PS groups was significant higher than that in other treatment
groups (P < 0.05). The antibacterial activity in the control was
significantly lower than that in other treatment groups (P < 0.05)
except that PS1 and PS3 were significantly higher than that in the
Florfenicol group (P < 0.05). The PO in the control group was significant
lower than that in other treatment groups (P < 0.05) except
PS1 and there were no significant differences among other treatment
groups (P > 0.05).
