This experiment was conducted to study the effect of adding different levels
of thyme leaves powder to broiler ration at levels of 0 , 0.2 , 0.4 , 0.6 % for
treatments C,T1, T2, T3 respectively and one does of of chlortetracycline
antibiotic which was 150 gm of antibiotic / tone of feed (stimulate growth level)
for treatment Ab to show the effect of these treatments on some blood
characteristics of broilers. With continuous adlibitum feeding of this ration from
7 – 47 day of age. The results showed at 35day there was Significant decreased
in cholesterol concentrate of blood serum to treatment T1، T2 and Ab as
compared with C and T3 treatments . Where as significant decreased of total
protein concentrate in the blood serum for the treatment T1 compared with other
treatments also significant increase in uric acid concentrate in blood serum for
treatment Ab compared with C ،T1، T2 and T3 .As for antibody against
Newcastle disease there was significant increased for treatment T2 compared
with other treatment and at age of 47 day the results also showed that there is no
significant differences in cholesterol concentrate and total protein in blood
serum between all treatment and significant decreased happened in uric acid
concentration in blood serum for treatment Ab ، T1 and T3 compared with
control treatment C . As for antibody against Newcastle disease in blood serum
the results showed significant decreased for treatment Ab compared with other
treatment , AS for enzymes concentrates GOT and GPT in blood serum there
was no significant differences between the treatment during that period while
significant increased in enzymes concentrate ALP in blood serum for treatment
T3 compared with treatment T1
