Abstract

This study has been conducted to study the effect of experimentally
infected broiler chicks orally by two dosages of Listeria monocytogenes in
the percentages of serum protein of 30 broiler chicks at 7 and 15 days of
infection . The birds randomly distributed into three treatments , T1 : control
group , T2 : chicks orally infected by 6 X 405 CFU of L. monocytogenes , T3
: chicks orally infected by 34 X 4010 CFU of L. monocytogenes. The data
obtained revealed the following :-
Percentages of serum Pre-albumin , Albumin , Total albumins and  -
Globulin were decreased significantly (P<0.05) , in the same time
Post_albumin ,  ,  - Globuluins and Total globulins increased significantly
(P<0.05) in broiler chicks orally by the two dosages of L.
monocytogenes (T2 and T3) compaired with control group (T1) after 7 days
of infection , whenas a significant (P<0.05) increase in immunoglobulin
percentage (- Globulin) with Transferrin in the same time other proteins
return to its normal percentages after 15 days of infection , which indicated
of development immunity and inhanced chicks health at this age . No
differences appeared in chicks serum protein due to the listeria infection
dosages in this study
