FAMS Exam 1 Flashcards
What drives the bus for the history of a dairy cow (i.e. what’s the most important information to get for a dairy cow’s history)?
(Days in milk)
What does LUMMAR stand for (i.e. the main 6 things to evaluate for a dairy cow)?
(Lungs, uterus, mammary, metabolic, abomasum, rumen)
What is the worst-built portion of the bovine?
(The lungs)
Where should you default if you find nothing else wrong with a cow with a fever of unknown origin?
(Lungs)
The uterus is a common cause of problems/pathology in a cow for the first how many weeks postpartum?
(2 weeks)
(T/F) Milk production can be used to distinguish between local and systemic mastitis.
(F, milk production is not a good indicator of whether the problem is local or systemic)
What presentation defines subclinical mastitis (what does the cow look like, what does the milk look like)?
(Normal cow, milk with elevated somatic cells)
What presentation defines systemic mastitis (what does the cow look like, what does the milk look like)?
(8-10% dehydrated, depressed, feverish cow down in milk (>50%) and watery to brown/orange milk)
What two organisms are typically the cause of systemic/toxic mastitis?
(Coliforms - E. coli and Klebsiella)
How are systemic/toxic mastitis-causing organisms obtained?
(From the environment)
Cows with severe systemic illness may have sub/normal/elevated temperatures (choose one).
(All of the above)
Describe a normal rumen contraction (how many in how many minutes and what it should feel like).
(3 contractions every 2 minutes, your hand and stethoscope should be pushed outward during the contraction)
(T/F) There are no normal pings on the left side of a cow.
(T)
(T/F) Lung fields are much wider in cattle than other species.
(F, much narrower)
If a cow’s eyes are sunken, you can assume they are at least what percent dehydrated?
(7%)
Subclinical ketosis usually occurs secondarily to another pathology causing what clinical sign in cows?
(Anorexia)
What are the two ways to distinguish between a normal and abnormal ping on the right side of a cow?
(The size, a normal ping is typically no larger than a flat hand and an abnormal ping can span 3-4 ribs/rib spaces; consistency, a normal ping is typically inconsistent while an RDA/RTA ping is prominent and consistent)
You tent the skin on a cow and the skin stays tented for 4 seconds, what percent dehydrated is this cow?
(4%)
How do you distinguish between an RDA/RTA versus a cecal torsion via pinging?
(The pings for a cecal torsion should extend into the paralumbar fossa whereas RDA/RTA pings do not)
Scars have decreased strength/vascularity/cellularity (choose).
(All three)
What is the difference between a contaminated and dirty wound?
(A dirty wound has an active infection present, contaminated just has debris or spillage but not an infection (yet))
What is the benefit to choosing vertical mattress sutures over horizontal?
(Horizontal can impinge on peripheral healing capillaries)
What are three ways to manage dead space?
(Suturing all tissue planes separately and accurately, use of drains, and pressure dressing)
How do hematomas increase risk of infection in wounds?
(Blood is a great growth media for bacteria)
What is the advantage to ruminants having increased vascular density in their bones and enhanced osteogenic layer in their periosteum with lots of osteoblasts?
(They have a great potential for bone healing)
Should you start or end your farm visit/day with a necropsy?
(End, and if live sick animals test healthy then sick then dead)
Formalin fixed tissue should be no more than how many centimeters thick?
(3-6 cm)
How should solid organs be cut for submitting after a necropsy?
(Bread loaf style)
(T/F) All veterinary diagnostic specimens are considered a category B infectious substance for shipping purposes and need a special label.
(T)
Optimally, samples submitted for microbiology and/or toxicology should be fixed/fresh (choose).
(Fresh)
What are the five locations that you will most likely encounter lymphosarcoma in a cow?
(Hearts, abomasum, uterus, lymph nodes, and spine)
You are presented with a cow with a mandibular mass. You palpate it, it is hard and bony, what is likely the diagnosis and what is the causative agent?
(Lumpy jaw, actinomyces bovis)
What is the treatment for bovine papilloma virus?
(Leave it alone)
(T/F) Melanomas in cows are usually ulcerated, fairly movable, painful, and about as firm as a testicle.
(F, melanomas in cows can be ulcerated or not, are fairly moveable, are non-painful, and about as firm as a testicle)
What are two ways to distinguish between a penile hematoma and water belly in cows?
(Penile hematoma → firm and penile prolapse, water belly → soft and no penile prolapse usually)
A lump or bump on the jaw area of a small ruminant is what until proven otherwise?
(Caseous lymphadenitis)
What is the most common location where squamous cell carcinoma pops up in small ruminants?
(Vulva)
You are presented with a vulvar mass in a small ruminant, what are you most likely to suspect it is?
(SCC)
Treatment success results from the joint action of what two things (one is applied by you the vet and the other has to do with the animal you are treating)?
(Animal defenses and appropriate drug treatments → no antibiotic is good enough without help from the animal)
You are treating calves on a farm which have previously been treated as apart of a large group in an attempt to prevent disease (metaphylaxis) with draxxin, which of the following drugs could/should you now be treating the calves with? There may or may not be multiple answers that are correct.
Zactran
Micotil
Excede
Nuflor
(Excede (ceftiofur/cephalosporin) or nuflor (florfenicol), the other two are in the same class as draxxin (macrolide))
If you expect ____ (a percentage) of calves or greater to be at risk for respiratory disease upon arrival to a farm, you should use metaphylaxis.
(35%)
You are currently dealing with an outbreak of respiratory disease in a herd of calves. At this time, you are still just treating individually identified sick calves but in what two situations would you pursue metaphylaxis?
(If you were to treat 25% or greater of the calves in the herd in one day OR if for three consecutive days, you have to treat 10% of the calves in the herd)
What three areas of the body are targeted by mycoplasma?
(Lungs (pneumonia), joints (lameness), and ears (ear infections, head tilt))
Why might calves with Mycoplasma infections be harder to identify for respiratory disease when compared to calves with Mannheimia infections?
(Mycoplasma does not produce the leukotoxin that Mannheimia does so calves with myco are usually not as ADR or off-feed like those with Mannheimia infections)
(T/F) Once a calf has joint issues related to a Mycoplasma infection, they will not be able to recover and should be euthanized.
(F, most calves will recover if given enough time and the appropriate husbandry (small lot with easy access to feed/water); myco attacks the joint capsules, not the cartilage itself)
What is the treatment for Histophilus somni?
(Prevention with CTC, 1 gm per 100 lbs body weight for 5 days)
Optimally how long would you wait and get the producer to wait after administering a long acting antibiotic prior to switching and treating with another antibiotic?
(48 hours, look for an improvement in attitude and appetite and a reduction in fever if there is one)
Of the following options, which is most important in preventing BRDC?
A - Vaccination programs
B - Metaphylaxis upon calf arrival
C - Appropriate calf purchasing, nutrition, and preventing other stressors
(C)
What are preconditioned calves?
(Calves that have been vaccinated at least 2 weeks prior to shipping, weaned for at least 45 days, and trained to eat and drink from a trough)
What vaccines should a preconditioned calf have received?
(IBR/BVD 1+2/PI3/BRSV combo, Mannheimia hemolytica, and 7-way clostridial/black leg)
What is appropriate processing for category 1 calves upon arrival to a new facility?
(Deworm them, delice them, and give them a coccidiostat)
What is appropriate processing for category 2 calves upon arrival to a new facility?
(Vaccinate with 5-way and 7-way within 24 hours of arrival, same parasite control as category 1)
Should metaphylaxis be considered for appropriate processing for category 3 calves upon arrival at a new facility?
(Yes, in addition to removing them from the market asap, providing fresh, clean water and free choice excellent quality hay, vaccinating them, administering parasite control and selenium, and +/- administering Pasteurella toxoid vax)
What is the most common sample taken for BVD testing?
(An ear notch, can then perform ELISA or IHC)
What is the toxic agent associated with wild cherries?
(Cyanide)
How does the toxin associated with wild cherries cause damage in the body?
(It irreversible binds oxygen to hemoglobin → venous blood will be bright ‘cherry’ red)
