A blanket approach to drying off is no longer permitted, instead your veterinary practitioner must adopt a selective approach to dry cow therapy
when prescribing dry cow mastitis tubes for your herd. With a selective approach, all cows are considered individually in terms of the risk of mastitis over the dry period. Your veterinary practitioner will determine if a dry cow tube is needed at drying off, in some cows an internal teat sealant alone will be sufficient. A selective approach involves doing a risk assessment at the individual animal level to determine which cows will need antimicrobial treatment over the dry period.
