Look dead
Muscles appear pale
Muscle tremors and flailing limbs
Cows go down rapidly and experience convulsions and neuro symptoms
5
What is sub acute acidosis?
Results from feeding increased concentrates compared to forages
Static rumen due to reduced microbial activity and contractions cease

Calves are hand fed with milk
8
Who is more vulnerable to traumatic reticulopericarditis?
young animals
Grain fed systems
Grass fed systems
Older animals
9
How is ruminal acidosis prevented?
Provide feed several times per day to spread out intake & reduce competitio
Avoid under and overfeeding
Reducing amount of readily fermentable CHO
Manage good diet formulation
10
How is rumenitis prevented?
Increase CHO
Increase dietary fiber
Decrease dietary fiber
11
How is white muscle disease prevented in calves?
Avoid grazing legumes with low fiber and high CHOs
Supplement cows in late gestation with selenium vitamin E
Avoid grain based rations with low fiber
12
What deficiency causes excitability, convulsions, and downers (grass & winter tetany)?
Magnesium
Copper
Iodine
Calcium & phosphorous
13
How is bloat prevented?
Avoid grain based rations with very low fiber %
Avoid grazing pasture with high fiber and low CHO
Avoid grazing legumes pasture with low fiber and high CHO
Avoid grain based rations with very high fiber %
14
What is the cause of ruminal acidosis?
Feeds with low sugar resulting in increased rumen pH
Feeding high level of rapidly digestable carbs (barely, other cereals)
15
What are clinical signs of ruminal tympany?
Long toe hooves
Sudden death
Distended abdomen and internal pressure can cause suffocation
16
Acute acidosis (death) is seen in cows that have obtained access to excess feed

True
False
20
How is grass tetany prevented?
Supplement vulnerable groups with pasture dusting, mineral licks
Feed more K+
21

22
How is bloat treated?
Give more leguminous pasture fed diets
Provide supplements like molasses & alkaline things
