Objective: To investigate the biosecurity measures practiced at commercial layer chicken farms in Abyek country, Qazvin, Iran..
Methods: In this cross-sectional study, all licensed and active commercial layer chicken farms in Abyek county, Qazvin province, Iran in 2019 were recruited. We used a risk-based weighted scoring system (Biocheck.UGent) to assess the level of biosecurity according to internal and external classification. Biosecurity was quantified by converting the answers to 169 questions into score from 0 to 100. The minimum score, “0,” represents total absence of any biosecurity measure on the farm, whereas the maximum score, “100,” means full application of all investigated biosecurity measures.
Results: The mean score of overall biosecurity in the commercial layer chicken farms in Abyek county, Qazvin province was 72.7. The mean score of internal and external biosecurity measures were 77.1 and 72.2, respectively. The lowest mean score was due to “Disease management” (69.7) among internal biosecurity measures and the lowest mean scores were for "Location of farm” (39.0) and “Removal of manure and dead animals” (42.6) among external biosecurity measures. The highest mean score was for “Transport of the eggs level” (91.0) for external biosecurity measures.
Conclusions: This study showed the biosecurity status of commercial layer chicken farms in Abyek county, Qazvin, Iran and revealed some weaknesses in the implementation of these measures at the internal and external levels. It showed the biosecurity measures of these farms, especially at the external levels need to be improved. This information can aid decision-making on efforts used to improve disease control and prevention strategies in poultry farms.
