Milk drop in a freshly calved cow Flashcards
define freshly calved
Generally means calved in the last few weeks (up to ~6wks??
List 9 differentials for milk drop in freshly calved milk cow
LDA/RDA
metritis
primary ketosis
Mastitis
Traumatic reticuloperitonitis
Peritonitis
caecal dilation
abomasal torsion
pneumonia
List which differentials for milk drop always cause pyrexia
Metritis
Salmonellosis
Mastitis
Pneumonia
Leptospirosis
List 6 differentials of milk drop that usually cause decreased /absent rumen turnover
LDA
RDA
Ketosis
Peritonitis
Caecal dilation +/- torsion
Abomasal torsion
List 6 differentials of milk drop that usually cause ‘ping’ on percussion auscultation
LDA
RDA
caecal dilation +/- torsion - sounds slightly different
Abomasal torsion
Describe how peritonitis presents in cows
tend to be mild/chronic clinical findings
+/- abdominal pain
+/- pyrexia
Describe how to diagnose peritonitis in cows
Can be challenging/by exclusion for chronic diffuse peritonitis
Tests for TRP may be positive
+/- pain on rectal examination
Describe how to treat peritonitis in cows
conservative:
- Antibiotics
- NSAIDs
- Fluid therapy - generally oral
Surgical:
- Ex lap- establish cause, debride/lavage
What is caecal dilation associated with
decreased GI motility
Describe the typical presentation of a caecal dilation
typical ‘sick cow’
may have colic signs if torsion
‘Ping’ caudodorsal R side
Describe how to treat caecal dilation(+/- torsion)
conservative - NSAID, calcium?
surgical- R flank laparotomy, externalise and empty (purse string suture), +/- reposition
What is abomasal torsion usually a complication of
RDA
describe the signs of an abomasal torsion
Often colic and more severe systemic signs, R side ‘ping’
describe how to treat abomasal torsion
R side laparotomy, empty, reposition and pexy
what is the prognosis with a abomasal torsion
prognosis guarded
