| Question Is selective dry cow therapy really an accessible option, and could it work for my herd? Answer Yes, this approach is not only effective, but more accessible than you might think. In recent years, udder health has improved significantly in many herds, with most consistently delivering milk under 200,000 somatic cells/mL. At the same time, the dairy sector is increasingly focused on reducing antibiotic use, making selective dry cow therapy a modern, responsible, and realistic strategy. In Canada, adoption is growing in 2023, 31% of producers had implemented this approach. According to Lactanet data, over 52% of herds enrolled in milk recording meet the criteria to adopt it successfully. In these herds, more than half of cows could be dried off without antibiotics, representing a potential savings of 480,000 tubes nationally. To support implementation, Lactanet offers a decision-making algorithm based on SCC data from milk recording and clinical mastitis history. This generates a Selective Dry Cow Therapy Report, identifying cows that are suitable candidates for drying off without antibiotics. This enables informed, on-farm decision-making without requiring additional steps. Other approaches, such as culture-based methods or combined strategies, may also be considered depending on available resources. The best approach should be discussed with your herd veterinarian, taking into account herd health status, available tools, and specific goals. Bottom line: the tools are available, the data is clear, and more than half of herds already have the profile to succeed with this approach.
