38
What is the normal rectal temperature range for adult sheep? Lambs?
Adult - 102-103.5 Lamb - 102.5-104
39
What is the normal rectal temperature range for adult goats? Kids?
Adult - 101.5-103.5 Kid - 102-104
40
What heifer/cow specific observations should be made during a PE?
Mucosal membrane color (vulva) If recent parturition - bruising, swollen/edematous vulva, udder edema Uterine/vaginal discharge/odor
41
What steer/bull specific observations should be made during a PE?
External genitalia
42
What small ruminant observations should be made during a PE?
Lower eyelid mucosal membranes
43
What part of a PE should be done before rectal palpation?
Auscultation
44
On what side of the ruminant are heart sounds generally louder?
On the left
45
What heart valves are on the left of the ruminant?
Mitral, aortic, and pulmonic
46
What heart valve is on the right of the ruminant?
Tricuspid
47
What sounds should you make sure to listen for in the lungs in cattle?
crackles and wheezes
48
What lung sounds can be normal in cattle?
bronchovesicular sounds
49
Why is respiratory disease often mis-diagnosed in small ruminants?
Because their lung sounds are easier to hear than cattle
50
Where is the heart located in relation to the thoracic limb in the cow?
It is right underneath (medial) to the crux of the elbow
51
Where is the imaginary line for the caudal border of the lung field in cattle?
From the costochondral junction of the 6th rib to the top of the 11th rib
52
Presence of rib fractures/enlargements are common in ________ following \_\_\_\_\_\_\_.
neonates, dystocia
53
Subcutaneous ________ (lung condition) is common in the post partum cow.
emphysema
54
A positive response to the withers pinch is a ______ and this is indicative of _______ disease.
grunt, hardware
55
What is hardware disease?
When a piece of metal pierces through the reticulum and into the thoracic cavity by poking through the diaphragm
56
Where should the rumen be palpated?
Externally in the paralumbar fossa
57
What should the rumen feel like normally? In dehydrated cows?
Normally it feels doughy, but becomes dry/stiff with dehydration
58
What should you be able to evaluate as you are palpating the rumen?
Rumen contractions, free gas distension, rumen fill
59
What are the 'layers' of contents typically in the rumen?
From bottom to top: Sediment, liquid phase, fiber mat, and gas cap
60
What should you hear when you auscultate the rumen?
A dull roar 1-3x per minute
61
What should you be listening for when you percuss (flick) the left side of the rumen (between the 11th and 13th rib and the paralumbar fossa)?
Pings - not valuable in small ruminants
62
What are the differentials for left sided pings?
Left displaced abomasum, empty gas filled rumen, free gas in the abdomen, and gas in the uterine horn
63
How do you differentiate a ping if you are trying to determine if there is free gas in the abdomen?
Slap over the lumbar shelf with an open hand and see if that elicits a ping - the gas will rise if it is free in the abdomen so you should hear a ping You can also ballot the abdomen to listen for sloshing or gas bubbles
64
What will a displaced abomasum feel like on rectal palpation?
You will feel a gas filled sac around the rumen
65
If you chose to pass a stomach tube and auscultate the rumen, what will you hear if it is an LDA?
muffled gas sounds
66
Where should you auscultate on the right abdomen for intestinal motility?
In the caudal ventral area
67
Why should you ballot during auscultation of the right abdomen?
To listen for liquid sloshing
68
When auscultating the right abdomen, what can you hear?
pings and intestinal stasis
69
What is an LDA associated with? A RDA?
LDA - early lactation RDA - not associated with any stage of lactation or other diseases
70
What increases the risk of an LDA?
Milk fever, ketosis, and metritis
71
How can LDAs be corrected?
surgical and non-surgical options
72
How is an LDA diagnosed?
With a ping on the left side
73
What is a RDA related to?
irregular feed intake and/or GI disturbances
74
Is an LDA or an RDA considered emergent?
RDA - because of torsion
75
How are RDAs diagnosed?
Distinctive 'ping' on the right side
76
What should be the primary differential in any ill male small ruminant?
urinary obstrution
77
If a male small ruminant acts constipated, what is likely the cause?
A urinary obstruction - this is an emergency
78
What lymph nodes are externally palpable?
pre-scapular, pre-femoral, supramammary, parotid, submandibular, and retropharyngeal
79
What lymph nodes are internally palpable?
Pre-iliac located cranial to the pelvis at the 4 oclock and 7 oclock positions
80
What should be examined/looked for during the oral examination of the ruminant?
Oral erosions, ulcers, vesicles, necrosis, the dental arcade, odor, and mucous membranes
81
What should you look for in the nares of the ruminant?
Discharges, erosions
82
What should you look for in the eyes of the ruminant?
Compare both eyes and look for discharge, ulcers, foreign bodies, etc.
83
What should the ears be evaluated for during PE of the ruminant?
That they are symmetrical and the temperature
84
What should the neck be evaluated for during the PE of the ruminant?
Skin tent for dehydration, swellings/abscesses, and the jugular furrow
85
What ancillary tests are often used in small and large ruminants?
Multistix or Ketostix, digital ketometers, iStat Blood Analyzer, California Mastitis Test (CMT), and pH assessment
