In the light of the above statements, choose the correct answer from the options given below
Show Hint
Mastitis Control Dynamics: Contagious mastitis spreads during milking (controlled by post-dipping & dry cow therapy). Environmental coliform mastitis occurs between milkings (controlled by clean dry bedding & J5 immunization).

- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
- Statement I is true but Statement II is false
- Statement I is false but Statement II is true

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Epidemiology of environmental coliform mastitis vs contagious mastitis: standard 5-point mastitis control plans target contagious parlor spread but fail against environmental pathogens.
Step 2: Detailed Explanation:
1. Statement I: The classic NIRD 5-Point Mastitis Control Plan (post-milking teat dipping, universal dry cow therapy, milking machine maintenance, prompt treatment of clinical cases, culling chronic cows) was specifically designed for contagious pathogens (S. agalactiae, S. aureus) and is largely ineffective against coliform mastitis (E. coli, Klebsiella). Hence, Statement I is true.
2. Statement II: Environmental coliforms are ubiquitous in feces, mud, and organic bedding. Teat canal entry occurs through direct environmental exposure between milkings (when teats relax after milking) rather than parlor transmission. Hence, Statement II is true and correctly explains Statement I.
Step 3: Final Answer:
Hence, Both Statement I and Statement II are true, matching option (A).
