The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
"Blitz therapy" is a specialized, intensive herd-health treatment strategy used in dairy veterinary medicine.
It involves the simultaneous treatment of all lactating cows, or all infected cows in a herd, during lactation.
The primary goal is the rapid eradication of highly contagious mastitis pathogens, particularly Streptococcus agalactiae.
Detailed Explanation:
Contagious mastitis caused by Streptococcus agalactiae can lead to significant economic losses due to elevated somatic cell counts (SCC) and reduced milk yield.
Unlike other mastitis pathogens, S. agalactiae is highly susceptible to intramammary penicillin-based infusions and resides almost exclusively within the bovine mammary gland.
Blitz therapy begins by testing milk samples from all cows in the herd to identify infected quarters.
Every cow identified as positive is treated simultaneously with intramammary antibiotics, regardless of whether she exhibits clinical signs.
This coordinated treatment strategy eliminates the reservoir of infection within the herd, preventing transmission during the milking process.
Because of the risk of milk residues and the rise of antimicrobial resistance, blitz therapy is reserved for targeted eradication programs under strict veterinary supervision.
Step 2: Final Answer:
Blitz therapy is an eradication and treatment protocol used for contagious mastitis in dairy herds.
