- rupture of aorta, cranial mesenteric or uterine artery
- cardiac tamponade
- arrhythmia
Name a few reasons for respiratory sudden death
Pneumonia and bloat
Most dead ruminants will eventually __
Bloat
Name some reasons for GI sudden death
Ruptured cecal or abomasal ulcer
Bacterial toxins (that may cause sudden death) produces endotoxemia by __ ,__ and __ . While exotoxins come from ___.
Gram negative mastitis, salmonella, grain overload
Blackleg C chauvoei
Name some metabolic reasons for sudden death
Hypocalcemia
Hypomagnesemia
Salt intoxification / water deprivation
Exogenous toxins that cause sudden death
Lead, Copper in sheep, Poisonous plants (Japanese yew, nitrates, cyanogenic plant), Urea toxicosis, monensin toxicosis, Insecticides
Selenium deficiency is more common in __ animals after exertion and can be diagnosed at necropsy by finding what?
Younger, finding white streaks in the heart (cheesy)
Rupture of uterine arteries most likely happens due to ___. Once the uterus is out there is __ on the arteries and you should __ bring the animal to the clinic because the arteries will __ and then when the put back in they will __.

__ disease and __ may cause cardiac tamponade
Hardware and heart tumors
How would legumes cause sudden death in a ruminant?

__ and __ are likely the cause of a ruptured abomasum or cecal ulcer
Cu deficiency and C perfringens
Anthrax produces ___ and ___
Lethal factor and edema factor
Hypocalcemia causes a lack of __ and __ which leads to heart failure. If treating an animal for this you should give calcium __ and monitor __.
Hypocalcemia causes a lack of muscle contraction and nerve conduction which leads to heart failure. If treating an animal for this you should give calcium slowly and monitor jugular pulses and heart rate.
Hypomagnesemia causes __ signs
Neurologic
