Abstract

This study was conducted to compare the effect of adding organic chromium (Biochrome) and
organic acids (Galli acids) for reducing experimentally infected broiler chicks by Salmonella
typhimurium . A total of 400 one day old broiler chicks were divided into four dietary groups which
were: un-treated negative control (T1) , 044 ppb organic chromium / kg feed (T2) , 4.0 of organic acids
/ kg feed (T3) and positive control (T4) . After one day of feeding T2 ,T3 and T4 chicks were oral
experimentally infected by S. typhimurium. Results have shown :
Mortality of positive control broiler chicks were 70 % , added organic chromium and organic acids
reduced chicks mortality tto 10 % in each , also the results revealed that the addition of organic acids
and organic chromium reduced S. typhimurium in the intestine content and its recommended for use to
prevention S. typhimurium infection in broiler chicks due to the improvement of health status
depending on the increase of lymphocyte cells number and immunoglobulin concentration after 10 and
21 days of experimentally infected , also the improvement in the live body weight and weight gain
