- Ruminal Acidosis
- definition
- decreased blood ph and bicarb
- overporduction of ruminal lactate - large amount concentrates consumed
- high carbs + reduced salivation = decrease rumen ph and acidosis
- acidosis favours lactic acid producing bacteria
- Acute
- large amount carbs short period (grain overload
- result bacteria death and decrease DMI
- lactic acid in rumen = dehydration and scour
- Subacute
- chronic mild depression of ph - chronic exposure low fibre, high starch lack long chop
- result in decreased salivation
- herd level problem
- large infrequent concentrate meals
- excessive starch
- Clinical signs
- Acute
- anorexia
- bloat
- ataxia
- weakness
- diarrhoea
- Subacute
- tail swishing
- variable diarrhoea
- decreased yield and feed intake
- poor reproductive performance
- Acute
- diagnostics
- rumenocentesis
- continuous monitoring ph bolus
- assess feed quality
- Treatment
- Acute
- rumenotmy
- IV fluids, calcium and gluconate
- oral antacids
- often results in chronic rumenitis
- Subacute
- distribute concentrate feeds across the day
- fibre content more than 35% (long grain)
- total sugar/ starch less than 25%
- include buffers in feed (sodium bicarb)
- goood mixing of rations and managing DMI
- Acute
