This study was conducted to determine the effect of Organic acid (citric acid), prebiotic (lactose) and aromatic plant (rosemary). added to a standard diet, to reduce or control the prevalence pathogenic bacteria and parasite in the intestine of broiler chicks reared under normal or heat stress conditions. Two hundred forty, unsexed one-week-old, Hubbard chicks were divided into groups of 60 birds each and randomly assigned to the four treatments. Each treatment has two replicates. Experiment was as follow: A control group with no supplement and the other three groups were supplemented with one of the following additives; citric acid, lactose or rosemary. At 35 days of age, each group was divided into two equal subgroups, the first was kept under normal conditions (23 °C) while, the second was exposed to 38°C for 3 hrs daily for 6 consecutive days from 35 to 40 days of age with 70 % relative humidity.
