Bovine Digital Dermatitis - M3 Stage,
lesion is healing so no treatment
What is the main goal of treating all active lesions (Digital Dermatitis) at once?
- To simplify farm management
- Improves welfare, herd mobility, and reduces disease pressure
- It’s a regulatory requirement
- To eliminate the use of antibiotics
Improves welfare, herd mobility, and reduces disease pressure

dermatitis?
* Non-steroidal anti-inflammatory drugs (NSAIDs) for pain

* Licensed antibiotic spray
* Only foot bathing
* Use of NSAIDs only
- Licensed antibiotic spray

What is digital dermatitis primarily associated with in dairy cattle?
* Decrease farmer morale
* Lameness and reduced milk yield
* Increased fertility
* Enhanced feed efficiency
- Lameness and reduced milk yield
(also decreased farmer morale as lost of cows can become lame and it is dificult to control)

* Warm, moist conditions
* High altitudes
* Indoor housing
- Warm, moist conditions
What is a common complication of untreated or unsuccessfully treated cases of
Interdigital Necrobacillosis?

* Sole Ulcer
- Deep digital sepsis
This is a hind foot. Based on the biomechanic
of cows, generally speaking, which of the two
claws tends to become overgrown (indicated by
the star in the image)?
Medial or lateral?
Lateral
You are now trimming the hind foot. In the
first step of the Five-Dutch Method, which is
