Biosecurity in dairy cattle farms in the North and Centre of Portugal
| Resumo: | There is an increasing understanding that lack of biosecurity and antimicrobial resistance are crucial points in animal production and the Animal Health Law emphasizes these two aspects. By implementing a questionnaire based on Biocheck from Ghent University‟s biosecurity assessment, this project aimed to make a characterization of dairy farms‟ biosecurity in North and Centre of Portugal, it aimed to create a biosecurity index, evaluate possible risk factors, characterize antibiotics use and create a tool that allows veterinarians to help and advise farmers. The questionnaire was implemented in 151 dairy farms through personal interview and through Googleforms; a report was built and sent to the veterinarians that participated in the project. The biosecurity aspects present in both questionnaire and final report are related to animal purchase, reproduction management, hygiene and disinfection, people and animal movements, health, calving, calf, adult animals, dairy and feed and drinking water management, with one group also added for antibiotic and vaccine use. A difference was observed between total biosecurity scores that went from 42 to 80.4 (in 100 points) and external and internal biosecurity mean scores of 71.3 and 67.7 (in 100 points) respectively. Variables with bigger influence in biosecurity scores were the ones related to the use of individual protective equipment, hands hygiene, cleaning of calving and sick pens and putting animals in quarantine. Regarding antibiotics‟ use, every farm treated animals with antibiotics, but only 47.4% had an antibiotic protocol for its responsible use. This means that there is still a lot to improve regarding biosecurity and awareness regarding the use of antibiotics, although a bigger sample should be taken to make a more reliable and significant characterization. |
