Intramammary antibiotics are antimicrobial medications infused directly into the teat canal to treat bacterial mastitis infections in the udder, available...
Intramammary antibiotics are the primary pharmaceutical intervention for bacterial mastitis. By infusing medication directly into the quarter through the teat canal, these products deliver high drug concentrations to the infection site while minimizing systemic exposure.
Lactating cow treatments address clinical mastitis—visible infections with abnormal milk, swelling, or systemic signs. Product selection depends on the likely causative organism, with different antibiotics targeting different bacteria. Treatment duration (1-8 days) varies by product and protocol. Milk must be discarded during treatment and through the labeled withdrawal period.
Dry cow therapy is administered at dry-off to cure existing subclinical infections and prevent new infections during the dry period. Traditional "blanket" dry cow therapy treats all cows and quarters. Selective dry cow therapy (SDCT) reserves antibiotics for infected cows while using teat sealants alone for uninfected animals, supporting antimicrobial stewardship.
Product selection requires matching antibiotic spectrum to target pathogens. Culture-based treatment decisions improve cure rates by identifying the causative organism before treatment. Gram-positive bacteria (Staph, Strep) respond to different antibiotics than gram-negative (E. coli, Klebsiella).
Responsible use includes following label directions, completing full treatment courses, observing withdrawal times, and working with veterinarians on treatment protocols. Antimicrobial stewardship principles guide appropriate use while maintaining treatment effectiveness.

Buying Considerations
Important factors to consider when evaluating What Are Intramammary Antibiotics for Dairy Cattle?:
- Pathogen spectrum coverage: Choose broad-spectrum antibiotics like ceftiofur for gram-negative coverage or penicillin-based products for primarily gram-positive infections based on farm culture results
- Milk withholding period: Consider economic impact of milk withdrawal - products range from 60-96 hours withdrawal, affecting $85-140 in lost milk revenue per cow
- Treatment duration and convenience: Single-dose products reduce labor and compliance issues compared to multi-day treatments, improving cure rates by 10-15%
- Product formulation and stability: Evaluate suspension vs. solution formulations for ease of administration and storage requirements, especially in varying temperature conditions
- Cost per treatment and bulk pricing: Treatment costs range from $8-25 per dose; volume discounts of 15-25% available for annual purchases over $5,000
