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?

3. Bloated
4. cold extremities
What is the treatment for milk fever?
IV calcium

Uterine infection; may be due to birth trauma, calving intervention, retained placenta, etc
What are clinical signs of metritis?
1. fresh cow
2. off feed
3. fever
4. vaginal discharge (odorous)
5. +/- 2ndary ketosis
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)
What are the signs of displaced abomasum?
1. fresh cow
2. off feed
3. decreased milk production
