There was a significant decrease (P 6 0.05) in feed consumption
ratio of the 0.5% S. officinalis compared to the other
treatments and the control at 3, 4, 5 and 6 week (Table 3). At
the end of the trial (42 days) there was also significant decrease
(P 6 0.05) in the feed consumption ratio for the 0.5% A. pavarii
(105.40 g ± 9.82) compared to the control which was
(144.83 g ± 13.20). Data indicated that feed consumption
was declined during the last two weeks of trial among all treated
groups when compared to the control group.
Table 4 shows the daily feed conversion ratio which indicated
a significant increase (P 6 0.05) in food conversion ratio
at first week of administration of three types of plants with
both concentrations. However, there has been an improvement
in the feed conversion ratio during the 2nd up to the 5th week
of trial in almost all treatment groups as compared to the control.
At the 6th week there was a significant decline (P 6 0.05)
in feed conversion ratio in groups treated with Salvia officinalis,
Zizyphus Vulgaris in both concentrations.
Table 5 shows the results of ceacal coliform count which
indicated that the treatment with 1% of (A. pavarii and Z. Vulgaris)
has significantly decreased (P 6 0.05) the coliform count
in the cecum of chicks from the first week of administration
whereas, the three types of plants with both concentration
showed a significant reduction in coliform counts compared
with control groups from the 2nd till the end of the experiment.
