Diseases Causing Lameness Flashcards
True or False:
Use of analgesia in the treatment of sole ulcers and sole abscesses (white line disease) is indicated, because there is unequivocal evidence from field trials (spontaneous cases on farm) that it reduces pain associated with these lesions and improves resolution of lameness, thus improving animal wellbeing.
False
Which of the following is the most common cause of lameness in beef cattle?
Hairy heel warts (digital dermatitis)
Corkscrew claw
Footrot
Sole abscess (white line disease)
Footrot
Which of the following would be the most appropriate next step to address the lesion shown in this picture. There is no swelling immediately above the coronet on the affected claw.
What I see in the picture: Diagnostic paring of the white line and sole on the abaxial region of the foot. At the deepest extent of the paring within the white line, there is an oval bleb of brown fluid seeping out of the sole.
Pare away any undermined sole being careful not damage the corium. Block the other claw if it is healthy to reduce the weight bearing on the affected claw and return the cow to their pen.
Treat with parenteral antibiotics to prevent complications of deep digital sepsis and return the cow to their pen
Pack the lesion with an iodine soaked gauze and bandage the affected claw. Block the other claw if it is healthy to reduce the weight bearing on the affected claw and return the cow to their pen.
Pare away any undermined sole being careful not to damage the corium. Block the other claw if it is healthy to reduce the weight bearing on the affected claw and return the cow to their pen.
True or False:
When performing diagnostic hoof trimming on a lame cow to identify the cause of lameness, all defects in the sole should be completely pared out until you get to normal sole (comes clean), find an abscess or draw blood (indicating you reached healthy corium).
False
Which of the following are appropriate, rational treatments for the lesion shown in this image (Select all that apply)?
What I see. Palmar aspect of the foot of a cow with severe heel erosions and a hyperemic, ulcerative skin lesion between the heel bulbs that is very sensitive when touched.
Parenteral Ceftiofur (Excede) at twice the label dose
Toptical tetracyline spray, no wrap
Topical “activated” copper non-antibiotic gel under a light foot wrap (few wraps of vetwrap) that will typically come off on its own in a few days.
Topical tetracycline under a light (few wraps of vetwrap) foot wrap that will typically come off on its own in a few days.
Topical “activated” copper non-antibiotic gel under a light foot wrap (few wraps of vetwrap) that will typically come off on its own in a few days.
Topical tetracycline under a light (few wraps of vetwrap) foot wrap that will typically come off on its own in a few days.
Which of the following are accurate regarding the location of lesions causing lameness in cattle (select all correct answers)?
The majority of lameness occurs in the foot.
The majority of lameness occurs in the rear limbs.
The majority of lameness occurs in the front limbs.
The majority of lameness occurs in the upper leg.
The majority of lameness occurs in the foot and rear limbs.
True or False:
Topical treatment of digital dermatitis (Hairy heel warts) results in rapid clinical resolution of lameness, however, in a high proportion of animals there is NOT lesion resolution and a recurrence of lameness associated with hyperemic, erosive and chronic proliferative lesions.
True

True or False:
Aggressive trimming of hoof wall and sole to remove all affected tissue is important for effective treatment and control of footrot in sheep.
False
Considering the presumed etiologic agent of Contagious Ovine Digital Dermatitis (CODD), which has been seen in the UK but not yet reported in the US, which of the following would be the most appropriate treatment if you identified a presumed CODD affected foot in a sheep?
Parenteral treatment with penicillin at the label dose
Topical tetracycline under a light foot wrap (few wraps of vetwrap)
Trimming away excess hoof wall
Topical tetracycline under a light foot wrap (a few wraps of vetwrap)
Which of the following pictures of feet would prompt you to recommend a client implement a program to control footrot in a US flock of 100 ewes in which 30% had feet that looked like those in the picture chosen.
A. Hoof wall separation, sole necrosis, interdigital dermatitis
B. Interdigital dermatitis, normal sole and hoof walls
Which of the following describes the observations made for a positive response to application of hoof testers to a claw with no obvious lesions on the foot?
Focalization and/or head shaking
Attempts to withdraw the limb ipsilateral to the tested claw
Bulging at the heel bulb of the tested claw
Contraction of the proximal limb musculature of the ipsilateral limb
Contraction of the proximal limb musculature of the ipsilateral limb
