Numerous viruses, such as the bovine rotavirus (BRV), the bovine parvovirus (BPV), and the bovine viral diarrhea virus (BVDV), can cause bovine viral diarrhea syndrome. The global livestock industry has been subjected to significant consequences due to this condition. This results in considerable losses and hinders the production of crucial resources such as meat and milk, which are indispensable for sustaining the world's population. It is crucial to develop a quick and precise way of simultaneously detecting BVDV, BRV, and BPV, as they often occur together in mixed infections. A triplex loop-mediated isothermal amplification-lateral flow dipstick (LAMP-LFD) assay that can concurrently detect all three viruses was introduced in this study. The amplification process involved 30 minutes of incubation at 65 °C. The limits of detection (LODs) for BVDV, BRV, and BPV were 2.62 × 10^1 copies/μL, 2.43 × 10^1 copies/μL, and 2.50 × 10^1 copies/μL, respectively. The triplex LAMP-LFD assay was further evaluated in 156 anal swab samples, and the results were in agreement with the results of fluorescence quantitative PCR (qPCR) in more than 99% of the cattle. This assay is expected for the quick identification of triplex viruses in the field because it has high sensitivity and specificity and doesn't depend on laboratory equipment or conditions.
