|
What are two preventative medicines given to a cow?
|
1. parasite control
2. vaccination |

|
What is Ketosis?
|
-results from cow being in a nagative energy balance; this leads to hypoglycemia (low blood sugar) & subsequent mobilization of fat for energy in liver; this then leads to production of keytones
|
|
|
What are the clinical signs of Ketosis?
|
1. Recently fresh cow (w/in weeks)
2. Off feed 3. decreased milk production 4. dry, hard manure 5. sweet odor to breath |
|
|
How is Ketosis treated?
|
IV glucose
|
|
|
What other thing(s) may lead to ketosis?
|
Any condition that causes the cow to go off feed may result in secondary ketosis
|
|
|
What is milk fever?
|
Hypocalcemia
|
|
|
What causes milk fever?
|
Results from sudden "loss" of Ca into milk and subsequent neuromuscular dysfunction
|
|
|
What are the clinical signs of milk fever?
|
1. fresh cow (w/in 3 days)
2. Down, unable to rise 3. Bloated 4. cold extremities |
|
|
What is the treatment for milk fever?
|
IV calcium
|
|
|
What is Metritis?
|
Uterine infection; may be due to birth trauma, calving intervention, retained placenta, etc
|
|
|

|
|
What is the treatment for metritis?
|
antibiotics (local +/- systemic)
|
|
|
What causes displaced abomasum?
|
Due to high concentration feeding leading to production of CO2 and volatile fatty acids in the abomasum
|
|
|
What happens in displaced abomasum?
|
Abomasum becomes buoyant and displaces from normal position on floow of abdominal cavity up b/w the rumen and body wall (LDA) or upon the right side (RDA)
