Set 4 Flashcards
1
Q
Displaced abomasum
A
abomasum shifts from ventral abdomen up the left or right side
-left more common; right more severe
2
Q
risk factors for displaced abomasum
A
poor intakes pre partum over conditioning in dry period ketosis RP metritis twins dystocia milk fever
3
Q
Clincial signs of displaced abomasum
A
decreased intake/appetite
decreased milk production
reduced rumen
able to elicit a ping when listening and percussing
clinical signs more severe if DA on right
4
Q
DA treatment
A
Roll cow- if left side(possible relapse) surgical options -open flank surgery -open surgery on abdomen -closed technique of using a toggle to attach abomasum to ventrum
5
Q
Subacute ruminal acidosis
A
optimal rumen pH: 6.4
SARA= daily episodes of rumen pH(5.2-5.8)
-difficult to detect
6
Q
Rumen response to low pH
A
as rumen pH drops- leads to reduction in appetite
- saliva will act as a buffer to help increase pH
- low pH reduces rumen motility
- rate of lactic acid absorption that creates issues, rather than total amount
- periodic drops in pH can cause issues
7
Q
Investigating possible SARA
A
paper ration -formulation errors -moisture in TMR what's fed -over-mixing -small particle size -insufficient refusals what's consumed -sorting -competition
8
Q
Cow comfort
A
cows should lie ~13 hours/day
stall design is important
dry cows need more space than milking cows
can manage with small stalls if provide adequate bedding
