This study was conducted to evaluate the level of adopted biosecurity measures in broiler farms based on manure bacterial load examination in Khartoum State, Sudan. To achieve the goal, a cross sectional study was conducted. Data and manure samples were collected from January to September 2018 from 12 close system broiler farms according to Non-probability Multistage Cluster Sampling Method in Khartoum, Khartoum North (Bahri), and Omdurman localities (4 for each). A standardized questionnaire was also conducted and used for data collection. A total of 12 manure samples were collected from one chosen broiler house in each farm to check the TVCs. All collected Data were subjected to descriptive and analytical statistic such as Chi square and ANOVA using SPSS. The Results of external biosecurity measures revealed that half of the total farms examined (50%) were at a distance between 500 m to 1km from the nearest poultry farm. The same percentage was obtained for no manure spreading from neighboring farms. However, frequent passage of other farms vehicles via near public road was reported in 50% of participating farms. The internal biosecurity results showed that all the examined farms (100%) prohibiting manure storage beside 75.0% of them remove the manure through the dirty area. Furthermore, workers protective wearing when contact waste and hygiene practicing after removing waste sometimes practiced by 75.0% of the participant farms. The mean of bacterial TVCs in manure samples was found below the cut-off level (6.01±0.78 cfu/g) with 95% confidence intervals of 4.48-7.37, 5.20-6.79, and 4.39-7.84 and mean TVC of 5.93±0.90, 6.00±0.50, and 6.11±1.08 cfu/g for Khartoum, Khartoum North, and Omdorman, respectively. No significant difference was obtained for log means of bacterial TVCs and farm location (F value=0.047 and P-value=0.955). In conclusion, despite that the bacterial counts in manure samples were below the cut-off level, poor hygienic practices were detected. Formulation of suitable procedures and regulations by official authorities for implementing biosecurity measures is recommended.
