Question

Which of the followings is not present in five-point contagious mastitis control programme in a dairy herd?

• A. Dry cow management and therapy
• B. Monitoring of udder health status
• C. Udder hygiene and proper milking management methods
• D. Culling of chronically infected cows

Hint:

The five-point plan is action-oriented: dip teats, treat clinical cases, dry-treat all cows, cull chronic cows, and maintain the milking machine.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The "Five-Point Plan" is a classic, highly effective farm management program developed in the late 1960s to control contagious mastitis (primarily caused by Staphylococcus aureus and Streptococcus agalactiae) in dairy herds.

Step 2: Detailed Explanation:
The classic five points of this mastitis control program are:
1. Post-milking teat disinfection: Dipping all teats in an approved disinfectant immediately after every milking.
2. Prompt treatment of clinical cases: Treating all clinical mastitis cases immediately with appropriate intramammary antibiotics.
3. Dry cow therapy: Treating all quarters of all cows with approved long-acting dry cow antibiotics at the end of lactation (Dry cow management and therapy - A).
4. Culling chronic cases: Culling cows that suffer from recurrent, refractory, or chronic mastitis infections (Culling of chronically infected cows - D).
5. Milking machine maintenance: Ensuring the milking machine is functioning correctly and maintained regularly to prevent teat damage (which is part of proper milking management methods - C).
While "Monitoring of udder health status" (e.g., using somatic cell counts or California Mastitis Test) is an essential part of modern herd health monitoring, it was not explicitly one of the action-oriented "five points" of the classic contagious mastitis control plan.

Step 3: Final Answer:
The activity that is not part of the classic five-point program is Monitoring of udder health status, corresponding to option (B).
