“…A possible explanation for this could be that the most used VD in the treatment had a long withdrawal period for milk (3–7 days). For farmers, use of VD with zero withdrawal time or use of non-antibiotic based treatments for the disease ( Makki et al., 2017 ; Sharma et al., 2018 ; Tison, Bouchard, DesCôteaux & Lefebvre, 2017 ) would be attractive for food and nutrition security, sustaining stream of incomes and stable livelihood base derived from milk ( Migose, Bebe, Boer & Oosting, 2018 ). Thus, efficacy should be the first concern, and so the selection of the VD should always be a medical option.…”
