Physical Examination of Cattle Lecture 2

Physical Examination of
Cattle
Douglas E. Hostetler DVM, MS
Indications:
When an individual animal requires
examination to allow diagnosis and
treatment for an illness
 Examination of a representative sample of
animals to investigate a herd outbreak of
disease
 Evaluation prior to completing health
certificates for intrastate or interstate
transport

Procedure:

Develop a systematic procedure for
performing a complete physical
examination
– Personalized
– Prevents omission of important information
– Enables easier recall of abnormal findings
Dr. Hostetler’s Physical Examination

Observe 1st from a
distance

Segregation from
herdmates
 Not possible in a
referral situation
Visual Observation:

Examination:

Restraint
– Chute
– Halter
– Headgate
– Ganglock
Examination:

Collect data most affected by sympathetic
tone first
– Urine Sample for Multistick analysis
– Rumination Rate
– Heart Rate
– Respiratory Rate
Urine Collection:

Gently rub the escutcheon in an upward motion
– Perineal region from udder to Ventral commissure of
the vulva
– Do not hold the tail!
– Collect sample in a clean container


Insert thermometer following urine collection
