Abstract EN

The study was conducted to detect the inhibitory effect of the cinnamon aqueous extract on the Salmonella typhymurium infection of broiler chicks.

A total of 60 Hubbard flex broiler chicks one day old have been raised for 35 days all chicks infected with S.typhimurium(3X104 )cfu\ml orally at third day of age , randomly divided in to two groups first group is the treatment group(T) received the aqueous extract while the second group conceders as control (C).

The results showed significant increasing(p<0.05)for group T in weight gain and feed consumption as compared with control ,also there is an improvement in feed conversion ratio & decreasing in mortality rate but its not significant, the total cholesterol & glucose level significantly decreases while total protein & globulin significantly increased,but no significant differences between tow groups in the concentration of albumin, calcium and phosphorus ,the results showed that the bacterial count decreased significantly at 10,20 days of age for the cecal content count and cloacal swabs samples and decreased numerically at day 20 of age for the cloacal swabs samples, we can conclude that cinnamonum aqueous extract have positive effects of some of the productivity and biochemical parameters and its negative effect on the S.
