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 1 st distance – Demeanor from a – Level of alertness – Responsiveness – Segregation from herdmates Not possible in a referral situation
Visual Observation: Proprioception Strength Lameness Head and neck position Udder symmetry BCS
Restraint – Chute – Halter – Headgate – Ganglock Examination:
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 Some Normal Values – pH 8 – Glucose Neg – Ketone Neg – Protein Neg-trace
Start on the Left From the rear forward
Rumination Rate Listen, count and record the primary and secondary rumen contractions over two full minutes – Mid Left Paralumbar Fossa Normal 1-2 per Minute
Direct Heart Rate, Rhythm and Sounds Left side – Intercostal Spaces 3-5 – Behind the elbow – Normal Rate?
48-84 Adults 70-100 Calves
Respiratory Rate and Lung Sounds Rate can be evaluated by observation of chest excursions – Normal 26-50 Sounds (triangle) – Point of elbow – T13 at Transverse Processes – Caudal to triceps Acoustic Percussion – Dullness Dorsal to the Heart Shadow?
SQ Emphysema Dorsally?
– Reach up and feel for it
Peripheral Lymph Nodes Prescapular Prefemoral Supramammary Parotid Submandibular
Superficial Veins Jugular – Pulses?
– Distension Caudal Superficial Epigastric – Distension?
– Swelling?
Abdominal Auscultation and Percussion Simultaneous Auscultation and Percussion – “Pinging” Entire Abdomen
Abdominal Auscultation and Percussion Simultaneous Auscultation and Percussion – “Pinging” Entire Abdomen
Left limbs and Udder Swelling of the limbs? – Fore and Rear Palpate left quarters of the mammary gland – Heat – Hardness (swelling) – Edema – Teat lesions
Proceed to Right Side
Right AV Valve Area – 3 rd to 5 Intercostal Space th Murmurs?
Heart Sounds
Respiratory System Mirror Image of Left Thorax – Crackles – Wheezes – No sounds – Emphysema
Peripheral Lymph Nodes Prescapular Prefemoral Supramammary Parotid Submandibular
Superficial Veins Jugular – Pulses?
– Distension Caudal Superficial Epigastric – Distension?
– Swelling?
Abdominal Auscultation and Percussion Simultaneous Auscultation and Percussion – “Pinging” Entire Abdomen
Abdominal Auscultation and Percussion Simultaneous Auscultation and Percussion – “Pinging” Entire Abdomen
Right Limbs and Udder Swelling of the limbs? – Fore and Rear Palpate left quarters of the mammary gland – Heat – Hardness (swelling) – Edema – Teat lesions
Collection of Milk California Mastitis Test – Relative concentration of somatic sells in the milk – 2 ml Milk from each quarter – Add Reagent – Look for coagulation Negative Trace 1 2 3 http://www.infovets.com/demo/demo/dairy/D100.HTM
Rectal Examination
Reproductive Tract
Female – Vaginal wall – Cervix – Uterine Body – Uterine Horns Oviducts – Ovaries Bursae – Internal iliac lymph nodes – Sublumbar lymph nodes Male – Intrapelvic penis – Prostate – Seminal vessicles – Ampullae – Internal inguinal rings – Internal iliac lymph nodes – Sublumbar lymph nodes
Rectal Examination Intra-abdominal Urinary System – Left kidney – Ureters – Bladder
Rectal Examination Digestive System – Right Cranial Abomasum – Central Small intestines – Left Rumen – Dorsal sac
Vaginal Examination If indicated by the rectal examination or history
Examination of the Head Eyes – Enophthalmus – Exophthalmus – Discharge – Corneal Opacity – Lenticular Opacity – Scleral Injection – Pupillary Light Response – Masses
Examination of the Head Nares – Discharge Unilateral/Bilateral – Plaques – Erosions – Hemorrhage/ Epistaxis – Flaring
Examination of the Head Oral Cavity – Dentition – Erosions – Vesicles – Masses – Blunted Oral Papillae
Examination of the Head Cursory Cranial Nerve Examination – 1-8 Submandibular Region – Lymph Nodes – Edema Brisket – Swelling – Edema
