 The examination of rumen comprises inspection, palpation, percussion and
auscultation.
 Rumen auscultation is done by keeping chest piece of stethoscope in the
center of paralumbar fossa.
 The frequency and amplitude/strength of ruminal motility and ruminal sounds
should be recorded.
 Note: Normal ruminal contractions
 1-3/ one minutes or 3-5/ 5 minutes.
 Hypomotility due to TRP, Indigestion, Rumen impaction, Toxaemia,
Dehydration, and Hypocalcemia.
 Hypermotility due to Vagus indigestion, Diaphragmatic hernia, and early
stage of bloat.
Rumen Motility

Gut Sound
 Abdominal (bowel) sounds refer to noises made within the small
and large intestines, typically during digestion.
 Auscultation of the abdomen allows for characterization of these
sounds as hypoactive, normoactive, and hyperactive.
 Normal bowel sounds
 Hyperactive bowel sounds: indicate an increase intestinal activity
 Hypoactive bowel sounds: indicate a decline intestinal activity.
 Absence of bowel sounds

 Identify those sounds and their causes;
 Intermittent noises
 Gurgling or clicking noise
 Rumbling
 Borborygmi
 Splashing
 Tinkling
 Metallic or ringing
 High pitched
 Drum, dull and hyper-resonant sounds

 Body condition scoring;
 Is a management tool designed to assess body reserves or
fat accumulation of an animal.
 Is a system to estimate the levels of fat and muscle coverage,
to identify whether an animal is too fat, too thin or a healthy
weight.
 It can also be used to monitor changes in an animal's weight
over time.
Body Condition of Animals

How to Estimate Body Condition of Cattle

 How to Condition Score in Sheep
 Condition score is assessed by handling the animal over and round the
back bone in the area of the loin above the last long rib (see Figure 2).
1. Locate the short ribs of the sheep, directly after the final, 13th long rib
(figure 2).
2. Using the balls of fingers and your thumb, feel the level of fat cover
over the vertical processes (spine) with your thumb and the level of
roundness of muscle and fat cover over the horizontal processes (short
ribs) with your fingers.
3. The final step is to assess the eye muscle and its cover by pressing the
fingers into the area between the vertical and horizontal processes.
Fig 2

 Skeletal check points on Goat
1. The spinous processes in the centre of the goats’s back behind the
last rib and in front of its hip bone.
2. The tips of the transverse processes.
3. The fullness of muscle and fat cover between spinous and
transverse processes.
4. Hollow in the flanks below the loin (fat cover on the rib cage, on the
ribs and intercostals (between ribs) spaces.
5. Fat covering on the sternum.

Estimation of Body Weight
 The domestic animals body weight estimation equation as
following;
 Equation of Equine body weight estimation:
 Weight (kg) = (girth measurement in cm) x (length measurement in cm)
 Equation of Bovine body weight estimation:
 Live weight in lbs. = Body Length x (Heart Girth)
11,900

300

Bwt in lbs = HG x HG x BL
300
400
If Hog/Sow Bwt < 150 lbs….add 7 lbs
to the final answer
301,330,280
301 - Yearling
330 - Mature horse
280 - Weanling
300
HG - Heart Girth
BL - Body Length
lbs – Pound, 1 kg = 2.2 lbs

Capillary Refill Time
 It is a useful indicator of perfusion of peripheral tissues and the state of
the cardiovascular system.
 The gingiva over the incisor teeth is lightly compressed with the ball of
the thumb to blanch the tissue.
 The time required for the blanched area to return to its original color is
the capillary refilling time.
 Normally this is between “1 and 2” seconds.
 In healthy animals, the CRT should be less than 2 seconds.
 A CRT of more than 5 seconds is abnormal, and between 2 and 5
seconds may indicate a developing problem.

Examination of Visible Mucous Membrane
 Visible mucous membrane will be useful in giving the health
status of animals.
 Visible mucous membranes, which examined by inspection
include;
 Conjunctival,
 Nasal,
 Buccal
 Vaginal
 Rectal, Urethral, Cloacal
 The best mucosa to be examined is the conjunctiva, which
provides a good indication of the state of the peripheral
circulation.

 The normal colour of mucous membrane of different animals.
 Animal Colour of mucous membrane
 Cattle, sheep and goat……………Pale pink
 Horse……………………………..Pale roseate
 Pig………………………………..Reddish
 Dog…………………………….....Pale roseate
 Cat………………………………..Pale pink
Cont…

Abnormal color of mucus membrane
 Pale mucous membranes: due to a reduction in red blood cells,
and that results in a decreased oxygen delivery to the tissue.
 Blood loss anaemia.
 Parasitic infestations leading to haemolysis.
 Tumours or leucosis, Iron deficiency anemia.
 Long-standing infectious diseases.
 Exposure to X-rays and some medications.

 Congested mucous membranes
 High environmental temperatures and exercise.
 Any disease resulting in fever.
 Existence of infectious disease.
 Diseases of the heart, brain and its membranes.
Cont…

 Yellowish or Icteric mucous membranes
 Icterus of jaundice occurs due to increase of blood bilirubin
concentration (blood parasites, leptospirosis, hepatitis, cholangitis,
cholecystitis and cholangiohepatitis).
 Infectious anaemia and contagious pleuropneumonia of horses.
 Chronic gastric dilatation.
Cont…

 Cyanotic mucous membranes
 Bluish discoloration of visible mucous membranes resulting from
presence of reduced haemoglobin in blood capillaries.
 Myocarditis, pericarditis or cardiac insufficiency.
 Existence of heart or lung dysfunction.
 Plant and mineral intoxications.
Cont…

 Petechial hemorrhages
 Existence of infectious diseases and dysfunction of cardiovascular
system.
Cont…

 Examination of Lymph Nodes (L.N) had an important role in
the diagnosis of different diseases affected animals.
 Examination of L.N includes;
1-Examination by Inspection (Less important)
2-Examination by Palpation (More important)
3-Obtaining biopsy specimens
Examination of Lymph nodes

 During examination of Lymph Nodes we have to note the following;
1-Examination of the size
2-Any Felling of pain sensation/reaction during examination
3-Presence of L.N lobulations
4-Examintion of the consistency of the L.N
5-Examination of temperature of the overlying skin
6-Abscess formation
7-Examination of maturation and presence of discharge
8-Presence of adhesion between the L.N and adjacent tissues
9-Unilateral or bilateral affection
Cont…

Cont…

 Superficial Palpable Lymph Nodes (L.N)
1- Submandibular L.N
 Situated and are palpable on the medial aspect of the ‘angle of the jaw’
where the horizontal and vertical rami of the mandible meet. (Normal size
is 1.5 to 2 cm).
2-Prescapular L.N
 In cattle and sheep: Its presence in the front and slight dorsal to the point
of the shoulders (Forward to the shoulder point) just anterior to the
shoulder joint. (Normal size 1 cm × 3.5 cm).
 In horses (Non Examine) because it lay on the anterior border of the
anterior deep pectoral muscle.
Cont…

3- Prefemoral L.N (Precrural)
 In cattle and sheep: Its present above the fold of the flank dorsal
to the stifle.
4-Supramammary L.N
 In cattle and sheep: They are present on the caudal aspect of the
udder just above the upper limit of the mammary glandular
tissue. (Normal size 2.5 cm)
 In cattle they divided into two parts right and left each part have
two lobes.
Cont…

Prognosis
 Prognosis- giving prognosis means expressing an opinion as
to the probable duration and outcome of the disease.
 Prognosis can be classified into;
 Favourable
 Doubtful
 Poor
 Guarded
 Grave

 Favourable Prognosis
 100% surety of recovery in case of Favourable Prognosis. For example,
uncomplicated traumatic peritonitis in cattle.
 Doubtful Prognosis
 50% chances are there in Doubtful Prognosis, which clinician cannot
estimate or determine the extent of damage. For example, traumatic
reticulo-peritonitis with adhesion of diaphragm with abdomen.
 Poor Prognosis
 25% chance of recovery in poor prognosis cases. For example, traumatic
reticulo-peritonitis complicated by abscess in liver.
 Guarded Prognosis
 Serious condition with uncertain outcome is the Guarded Prognosis.
For example, Dog affected with chronic kidney disease.
 Grave Prognosis
 100% surety of death or fatality in Guarded Prognosis. For example,
traumatic peritonitis following penetration of sharp foreign object.
