Internal Teat Sealant as an Alternative to Intramammary Antibiotics at Dry-Off in Low-Risk Dairy Cows Effects on Udder Health, Milk Yield, Antimicrobial Use, and Economic Outcomes.
Clinical evidence update from Animals : an open access journal from MDPI
Clinical Context
Peer-reviewed veterinary literature continues to shape everyday decision-making for production animal practice, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.
What the Study Evaluated
A study published in Animals : an open access journal from MDPI in 2026 evaluated internal Teat Sealant as an Alternative to Intramammary Antibiotics at Dry-Off in Low-Risk Dairy Cows: Effects on Udder Health, Milk Yield, Antimicrobial Use, and Economic Outcomes..
Key Findings
Selective dry cow therapy (SDCT) has emerged as a key strategy to reduce antimicrobial use in dairy production while maintaining udder health. This study aimed to evaluate the feasibility and impact of implementing SDCT in Romanian dairy farms by comparing low-risk cows treated with internal teat sealant only (ITS) at dry-off with low-risk cows treated with intramammary antibiotics at dry-off. A prospective field study was conducted on two commercial dairy herds, including 87 cows classified based on somatic cell count (SCC) and differential SCC (DSCC), and compared with a historical cohort of 37 cows. Udder health parameters, milk yield...
Why It Matters for Veterinary Professionals
For veterinary professionals, the practical value of this work lies in how the findings may support more structured clinical assessment, clearer monitoring, and more informed decisions for production animal practice.
Practical Interpretation
The results should be interpreted in the context of the study design, population, inclusion criteria, and clinical setting. Application in practice should consider patient-specific risk factors, available diagnostics, local standards of care, and clinician judgment.
Clinical Takeaway
Overall, the study adds useful evidence for clinicians seeking to align daily practice with current veterinary research while maintaining a balanced, case-by-case approach.
