Q

Cause of milk fever

A

rapid onset of milk production causes acute depletion of Ca

17
Q

1st stage of milk fever is…

A

very short near - hypersenstivity

18
Q

2nd stage of milk fever is…

A

sternal recumbency with low temp, bloat

19
Q

3rd stage of milk fever is…

A

flaccid muscle in lateral recumbency, coma

20
Q

how long does the response to treatment for milk fever take

A

immediate if it is going to work

give Ca borogluconate IV slowly or PO if can swallow-keep them down

21
Q

prevent of milk fever

A

feed anionic salts during the dry period= DCAD should be - in dry and + during lactation
give paste during calving and no alfalfa or legume during dry period

22
Q

what kind of cows are most likely affected by hypophosphatemia

A

grazing cow-young and heavily lactating

23
Q

when do you see postpartum hemoglobinuria with hypophosphatemia?

A

postpartum within 6 wks after calving

24
Q

CS in young animals with hypophos

25
CS in adults with hypophos
osteomalacia, spontaneous fractures, hemoglobinuria
26
Tx for hypophos
sodium acid phosphate IV
27
when do you hypomag?
cattle fed on lush green during cool growing season
28
CS for hypomag
hyper excitable, staggering to recumbency, nystagmus, salivation
29
T/F can see hypocalcemia and hypophos with hypomag
true
30
tx for hypomag
magnesium hypo phosphate, Ca PO - can prevent with supplements
31
Def'n of Downer cow
stays in sternal recumbency for >24 hours after being found lateral = dead normal CS
32
Downer cow associated with what risk factors
``` milk fever BCS @ calving - large high production hx 5-8 yrs ```
33
What will you see on blood panel of downer cow
AST, CPK high | proteinuria, myoglobinuria, ketonuria
34
When do you see lymphosarcoma with spinal involvment
around parturition due to increase of steroids which increase tumor growth
35
Two grave prognosticators of Downer syndrome
rise in CPK and BUN
36
Very important prevention of Downer cow
prevent hypoCa
