Abstract A cross-sectional study was conducted to evaluate the risk factors associated with the Salmonella infection status of dairy herds in Henan and Hubei provinces, China. Herds were assigned a Salmonella status based on the isolation of Salmonella from fecal samples obtained from adult lactating dairy cows. Information on potential biosecurity risk factors was collected using a questionnaire template via a 15-min face-to-face interview with dairy cattle producers from May 2020 to March 2021. The questionnaire consisted of 23 questions across two broad categories of potential biosecurity risk factors: farm and biosecurity managemental factors. A total of 48 farms were surveyed. In all (100%, 48/48) of the surveyed farms, although sick animals were separated from healthy animals using fencing, there were no strict quarantine protocols for newly introduced animals. Mixed species rearing was practiced in 35.4% (17/48) of the farms. Feces were removed more than once a day in 45.8% (22/48) of the farms, whereas the remainder (54.2%, 26/48) only removed animal feces once a day. A total of 29.2% (14/48) of the farms were located |
