NH3 exposure stress
After NH3 exposure stress for 24 h, SR of all experimental groups
is shown in Fig. 2. SR was lowest in the control group, which was
also significantly lower (P < 0.05) than in 2.0, 4.0, 6.0 and 8.0 g kg1
MOS-supplemented groups. Meanwhile, SR was the highest in
4.0 g kg1 MOS-supplemented group, but SR had no significant
difference between 4.0 g kg1 MOS-supplemented group and 2.0,
6.0, 8.0 g kg1 MOS-supplemented groups.
