Basics of Diagnostic Plan + Field Necropsy Flashcards
What drives the bus for history on a dairy cow (i.e. what’s the most important information to get for a dairy cow history)?
(Days in milk)
What does LUMMAR stand for (not that this is a super significant acronym, it’s just helpful to remind yourself of what to look for)?
(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)
Subclinical ketosis usually occurs secondarily to another pathology causing what clinical sign in cows?
(Anorexia)
What presentation defines subclinical mastitis?
(Normal cow, milk with elevated somatic cells)
What presentation defines systemic mastitis?
(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)
You tent the skin on a cow and the skin stays tented for 4 seconds, what percent dehydrated is this cow?
(4%)
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)
