This study was conducted to investigate the effect of aqueous extract of Mentha
longifolia supplemented to broilers on some physiological parameters represented by
hematological characteristics .
A total of 90 chick of broiler faobre strain from IPA center for agricultural researches
were used at one day old . The birds at 4th day old , were randomly assigned into three
groups .
Each group consisted of thirty birds . The control groub ( c ) was not treated , T1
group treated with aqueous extract 1 ml / day of concentration 0.25 (gm / ml water) and
T2 group was treated with aqueous extract 1 ml / day of 0.125 gm/ml concentration and
for eight weeks .
All groups were fed the same commercial basal ration of broiler and the same
environmental condition and vaccinations were allowed to each group .
The results of blood samples tests were as follows .
Treated birds expressed high values of blood hemoglobin concentration and packed
cell volume percentage and showed significant difference ( p < 0.05 ) compared with
control group .
The birds ofT1 group indicated high significant
increased( p < 0.05 ) in total leukocytic count compared V
with the T2 & control group .
Theres is , significant increased ( p< 0.05 ) in numbers V
of TWBCS in T2 group compared with a control group .
A total erythrocytic counts revealed that there were Significant differences ( p <
0.05 ) between groupsln numbers of Red blood cells by increasing the number of red
blood cells in treated group .
These results refered to the benefit of aqueous extract of Men!/m /ongifolia to broiler
chicken at concentrations of 0.25 and 0.125 gm /ml
