A significantly (p 0.05) higher lysozyme activity was found in
group D on day 30 and day 60 of the feeding period as compared
with the control group as well as other treatment groups. Therewas
a significantly (p 0.05) increased lysozyme activity in groups B, C
and D as compared to group A on day 30 and day 60. However on
day 90, the level was increased in groups B and D and decreased in
group C. In post-challenge samples, the lysozyme activity was
increased significantly (p 0.05) in groups B, C and D as compared
to group A. However, in group B, the lysozyme activity was almost
the same as on day 90 pre-challenge
