forms, incidence, etiology/causes and predisposing factors
- Way of food
- Abomasum - true stomach, glands - hl, ph 3,5, important for calves.
Diseases:
- Abomasal displacement (left sided LDA, Right sided RDA + torsion)
- Abomasal inflam and ulcer
- Abomasal obturation/obstruction
Causes:
-nut, genes, anatomy after calving, metabolic disorder (ketosis,ulcer, endometritis)
Predisp:
-Peripartum, herd management, negative energy, hypocal)
- (A) Pathogenesis of the abomasal displacement, general and local consequences of
abomasal displacement
inc grain dec fiber –> inc VFA –> hypomotility –> dilatation –> displacement
Other causes: genes, nut, metabolic disorder.
Cons: -Hypochloraemia -Hypokalemia -dehydration -paradox acidouria -RDA with torsion - ischaemia -gas production -other part rotate -metabolic alkadosis -

Signs: anorex, dec milk, reduced feces, metal ping sound where sprung stomach 9-13th rib, splashing sound, pneumomediastinum, gas.
Diag:
-Rectal - feel gas-ping, secondary ketosis, splashing.
- (B) Clinical signs and diagnosis of the right sided abomasal displacement
signs:
- anorex, dec milk, basic values up reduced feces, dehyd, weak, pain, more severe than left, ping sound -10-13th rib, liver medial displacement.
Diag:
-Acute signs, exclude cecal dilatation, small intestine ileus, ping and splashing.
- Abomasitis, abomasal ulcer
Primary (stress,grass,fertilizer)
Secondary (displace, BVD, salm)
