- Left Displaced Abomasum
- definition
- abomasum fill with gas and rise to LHS
- decreased DMI around calving lead to hypoglycaemai, systemic disease and fatty liver disease = decreased motility
- decreased motility=build up gas = reduced feeding= more space
- risk factors
- obese cows at calving
- poor calving management
- periparturient disease
- poor feed access
- lack dietary long fibre
- poor control of energy balance around calving
- sudden increase of concentrates
- hypoglycaemia
- Signalment
- post calving
- sprig time - lack of fibre in spring grass
- Clinical signs
- decreased milk yeild
- decreased feed intake
- poor rumen turnover
- underlying primary disease (mastitis/ metritis)
- diagnostics
- auscultate abdomen = ping sound
- prevention
- maximise DMI around calving/ early lactation
- transition diet to long fibre
- treat underlying disease
- Treatment
- conservative
- roll
- oral propylene glycol
- oral fluids/ electrolytes
- long fibre diet
- usually 70-80% relapse
- semi-surgical
- roll cow
- insert toggle through trocar into abomasum while cow in dorsal recumbency
- surgical
- conservative
- definition
