      Abstract
      Laying hen is raised and selected to produce eggs. Poultry could be infected by several kinds of Salmonella enterica such as S. enteritidis as a specific bacterium which is carried by chickens. Salmonella enteritidis can depress the hen weight by dehydration and contaminate the egg which is very dangerous for human health. Regarding this negative effect, the preventive treatment to eliminate Salmonella enteritidis contamination in eggs becomes a major concern. This research aimed to determine the optimum dosage and frequency applied ofprobiotic L.acidophilus to avoid contamination of Salmonella enteritidis in ovary and egg of laying hens. The result showed that probiotic treatment could increase feed consumption, egg production, however, in the other hand decreased the feed conversion. Among other, probiotic treatment was effective to reduce the population of Salmonella enteritidis in ovary and egg of laying hens. The optimum dosage of L.acidophilus probiotic was within population of 109 cfu/ml and frequency of twice a day was the most effective as biocontrol.
