Feed Toxicoses Flashcards
What average feed particle size is acceptable for all classes of swine?
700 - 800 microns
What feed particle size is too course for optimum feed utilization by swine?
> 800 microns
Too fine of a feed particle size could cause what?
Gastric ulcers
Feed particle standard deviation greater than ____ is undesirable.
2.0
Feed particle standard deviation greater than 2.0 is undesirable because it promotes what?
Ingredient separation
What feed particle size is most optimal for feed efficiency in cattle?
1628 microns
What feed particle size is most optimal for maximum gain in cattle?

What is the MOA with sodium ion - water deprivation?
Sodium moves into the brain tissue with dehydration, causing decreased energy metabolism and impaired sodium pumps. Water than follows causing cerebral edema.
Which species is MOST susceptible to sodium ion - water deprivation?
Swine
What clinical signs would you see with sodium ion - water deprivation?
- Thirst
- Constipation
- Blindness
- Circling
- Head pressing
- Seizures
What type of brain lesion is pathoneumonic for sodium ion - water deprivation in the pig?
Eosinophilic meningoencephalitis with perivascular cuffing
What would the ppm of sodium be in healthy pig brain tissue?
800-1200 ppm
What would the ppm of sodium be in brain tissue of a pig with sodium ion -water deprivation?
> 1800 ppm
What would the concentration of sodium be in the CSF with sodium ion - water deprivation?
> 160 mEq / L
What would the ppm of sodium be in brain tissue of a cow with sodium ion -water deprivation?
> 2000 ppm
