You are presented with a newborn Holstein heifer calf that is 6 hours old. The calf is approximately 80 pounds and was pulled by the owner. The owner came to you for assistance because his esophageal feeder broke and the calf won’t suckle a bottle. The owner brought his own colostrum from the cow. Which of the following is most appropriate to best help the producer?

You are called to evaluate a lamb that is having trouble walking.  The ewe lamb is approximately six  months old, and she is the only animal in the group that is abnormal.  When she was a week old she had an infection at the site where her tail was docked (amputated as a normal production practice), but it cleared up after the owner gave her some penicillin at the dose on the label.  The lamb has been growing well until about a week ago, when the owner noticed she was walking abnormally.   On physical examination she is alert and in good body condition.  She has a normal rectal temperature, heart rate, and respiratory rate, with no physical exam abnormalities outside the nervous system.  A neurologic examination reveals the lamb to have normal mentation, no cranial nerve abnormalities, and normal strength, sensation, and proprioception in her forelimbs.  However, she is very weak and ataxic in both hind limbs, and when you try to get her to walk, she sways side to side and falls down into a dog-sitting position.  She does have a withdrawal reflex in both hind limbs. Given the history and your examination findings, and assuming no financial constraints, which diagnostic test would you run FIRST to try to rule in the MOST LIKELY cause of this lamb’s signs?

A valuable heifer is presented to you for evaluation of unilateral right sided mucopurulent nasal discharge.  Careful examination reveals a solid, firm, gray-pink mass in the nasal passage.   Because the heifer is quite valuable, the owner wants to try to identify the cause and treat the problem, so you biopsy the mass.  When you submit samples to your diagnostic lab, which diagnostic tests should you request?

Mites are a common cause of alopecia, crusting, and pruritis in ruminants and camelids.  Of the mites that can affect ruminants, the most common mite tends to affect the distal extremities and perineum, causing mild to moderate pruritis.  Because this mite does not burrow into the epidermis, topical treatment with insecticides such as lime lime sulfur dip tend to be more effective than injectable products.  This mite is:
