  1. 3 types of primary ketosis.
    alimentary, hepatic, mammary
  2. What causes secondary ketosis?
    conditions that limit energy consumption at a time when energy demands are high
  3. Milk production peaks at _________, but energy intake doesn't peak until ___________.
    3 weeks; 7 weeks
  4. How much fat and protein/muscle can you expect a cow to lose in her first 7 weeks of lactation?
    2# of fat and 1/2# of protein broken down daily
  5. How much does does subclinical ketosis cost?
  6. Subclinical ketosis causes milk to drop ________ daily.
  7. Subclinical ketosis is a risk factor for... (3)
    clinical ketosis, metritis, LDA
  8. What causes ketosis in beef cows?
    biggest energy demand is growing fetus in late gestation, esp with twins; cows fed corn stalks and protein lick tank--> not enough energy
  9. What are the biggest energy demands?
    lactation, nervous system, fetal growth, muscle
  10. Alimentary ketosis occurs in cows on a ________ diet; the _________ of high-moisture silage can lead to cows of __________ developing ketosis.
    high protein; butyric acid; all stages of lactation
  11. What causes hepatic lipidosis?
    lactation causes mobilization of body fat reserves that must be converted in the liver--> mobilization exceeds liver's ability to convert fat to glucose due to build up of acetylCoA--> shifts to production of ketones
  12. What are clinical signs of ketosis? (5)
    inappetence, dry, shiny stool, gradual drop in milk, +/- neurologic signs (abnormal licking, chewing, staring, aggression, hyperesthia)
  13. What is a consistent neurologic feature of ketosis?
  14. How do you diagnose ketosis?
    ketone bodies in urine, blood, or milk
  15. Most sensitive, least specific way to measure ketone bodies.
  16. Least sensitive, most specific way to measure ketone bodies.
  17. How do you treat ketosis? (5)
    500mL 50% destrose, insulin (ultralente or PZI), niacin, propylene glycol, dexamethasone
  18. Why do you give insulin to treat ketosis?
    decrease fat mobilization in liver (anabolic)
  19. When is it inappropriate to given a ketotic cow propylene glycol?
    if she is not ruminating
  20. Hepatic lipidosis usually occurs in...
    fat cows, embryo donor cows, extended dry period cows, excessively thin cows
  21. Hepatic lipidosis increases susceptibility to... (2)
    severe mastitis and metritis
  22. Clinical signs of hepatic lipidosis. (5)
    shiny/dry stool, loss of appetite for concentrates, increase SDH, GGT, AST
  23. How do you treat hepatic lipidosis?
    same for ketosis but more intense and ALWAYS add systemic antibiotics
