Biosecurity is the practice designed to prevent the spread of diseases onto farm, with in farm and out from the farm. It has three major components, isolation, traffic control and sanitation. Good biosecurity should be practiced at all the time and it is the cheapest and the most effective means of disease control. Therefore, objectives of this study were to evaluate and grade the commercial broiler farms according to the present biosecurity status and to correlate the performances with biosecurity status of those farms. A questionnaire covering all basic conceptual, structural and operational aspects of biosecurity was used to collect data from 80 commercial broiler farms in Central Province of Sri Lanka. Minitab software was used to analyze the data. There is a significant negative correlation (p<0.05) between average catching age with overall biosecurity status. The average body weight has shown positive correlation while average mortality% and FCR having negative correlation though not statistically significant (p< 0.05). The biosecurity status of most farms falls to category of “Average” representing about 56%, while “Good” and “Poor” had about 15% and 27% of farms, respectively. There were very few broiler farms found in categories of “Excellent” and “Very poor” in terms of overall biosecurity status.
