You examine a lame Holstein dairy cow. This image is of one of the claws of the lame foot, the other claw is healthy (i.e. no lesions present). What is the most appropriate treatment for this cow?
- Corrective trim + block the healthy claw + NSAIDs
- Antibiotic therapy + NSAIDs + move to straw pen
- Corrective trim + apply copper sulphate powder and a bandage
- Amputation of this digit
- Corrective trim + block the healthy claw + NSAIDs
What is the current proposed theory regarding pathogenesis of claw horn
lesions?
* Claw horn lesions are related to increased pressure on the dermis
* Claw horn lesions are secondary to laminitis, which is related to subacute ruminal acidosis (SARA)
Claw horn lesions are related to increased pressure on the dermis
You are called at the weekend to attend a down cow. When you arrive, the
cow in question is a beef suckler cow at grass with a 6 month old calf at
foot. The herd is spring calving and the calf was born in April. On
examination the cow is in lateral recumbency and exhibiting grand mal
seizures. What is the most appropriate approach to this case?
* Immediate euthanasia on welfare grounds
* Sedate with xylazine and provide supportive IV fluid therapy
* IV green top calcium spiked with a small amount of magnesium (or unspiked IV red top calcium) + SC magnesium
- IV green top calcium spiked with a small amount of magnesium (or unspiked IV red top calcium) + SC magnesium
One of your farmers has decided to return
to sheep farming after having a break of a
few years and recently bought 50 new
ewes, now approximately 20 are lame.
The farmer sends you this picture and
asks your opinion. What is the most likely
diagnosis?
- Contagious ovine digital dermatitis (CODD)
- Foot rot
- Interdigital dermatitis
- Toe granuloma
- Contagious ovine digital dermatitis (CODD)
A client asks you to look at their lame pet chicken. You try to explain that you are a small
animal vet and chickens are farmed animals but they are insistent. Plus, the chicken is in the consulting room now anyway so what are you going to do?! You have a look and identify a lesion on the underside of the chicken’s foot. After seeking a second opinion from your colleagues, you decide to treat this chicken with some antibiotics and NSAIDs but the client is worried about it possibly recurring or affecting others in the flock. What further advice do you give?
- This is likely to be a traumatic injury so probably won’t affect any others and is unlikely to recur
- Improved husbandry can aid prevention. You suggest that the client starts by seeing
if the cleanliness of the environment can be improved
- Improved husbandry can aid prevention. You suggest that the client starts by seeing

A smallholder with 5 Landrace sows brings in a
piglet to the practice. The piglet is three days old and was the smallest in the litter. The owner has noticed it is unable to stand. When placed on the consulting room table, it’s hindlimbs are weak and unable to support it’s weight but the front limbs appear unaffected and the owner reports they have observed the piglet ‘dog sitting’. The piglet is otherwise well in itself and the owner is keen to try treatment if possible. How do you proceed?
- Recommend euthanasia as the prognosis is clearly very poor and welfare is compromised.
- Recommend spinal radiographs and reassess once you have a better idea what is going on
- Administer NSAIDs and recommend the owner provides good nursing care
- Advise the owner to provide good nursing care (especially feeding) and to either tie
the hind limbs loosely together to act as a splint and aid movement, or provide basic
physiotherapy including massage of the thigh muscles for 5mins 6-8x daily to encour-
age muscle development

It is late spring/early summer and all of a sudden lots of cases of neurological abnormalities in lambs are being seen by the practice. Typically, cases are recumbent and several of your colleagues report seeing opisthotonos. Some deaths are reported. What product do you ask for more to be ordered for the pharmacy to make sure there is enough for treating all of these cases?
- Clavulanic potentiated amoxycillin
- Meloxicam
- Vitamin B1
- Vitamin K
- Vitamin B1
Which of the following is NOT a clinical sign of Bovine Digital Dermatitis?
- Lesions typically found on the plantar surface of the hindfoot
- Severe lameness without visible lesions
- Lesions can appear around the coronary band
- Majority of lesions are found on hind feet
Severe lameness without visible lesions
What does an M1 score in the Mortellaro scoring indicate?
* No lesion present
* Healing lesion covered with firm brown/black scab material.
* Chronic stage with a “wart-like” overgrowth of brown-grey color.
* Active small lesion less than 2 cm with red-grey surface
- Active small lesion less than 2 cm with red-grey surface
What is the causative agent of Interdigital Necrobacillosis?
* Escherichia coli
* Fusobacterium necrophorum
* Treponema spp.
* Clostridium perfringens
- Fusobacterium necrophorum
What is the target for lame cows (lameness index) in a dairy farm?
* 20-30%
* 40-50%
* 30-40%
* less than 10%
- less than 10%
You diagnose a calf with septic meningitis. The calf is recumbent and
obtunded and has a grave prognosis but the owner refuses euthanasia and
wants to attempt treatment first. Which antibiotic treatment would be your
preferred choice for this case?
* Amoxycillin
* Enrofloxacin
* Trimethoprim sulphonamide
* Ceftiofur
- Trimethoprim sulphonamide
amoxycillin preperations is not IV and we want this to be an IV route as this calf is very sick and it will be quicker acting
