Rumenal Function Flashcards
What is the purpose of the primary reticulorumen contraction?
To facilitate mixing of the dry dietary fiber w/buffered saliva & fermentative bacteria
How long after feeding concentrate vs. offering a TMR is best to analyze the pH of the rumenal fluid?
2-4 hours after feeding concentrate;
4-8 hours after TMR
Rumen fluid with a pH<5.5 indicates what?
Rumenal acidosis
What’s the difference between free gas bloat & frothy bloat?
Free gas: (usu. 1 animal) result of underlying primary dz
Frothy: primary dz—> inability to breakdown feedstuffs; ruminal gases trapped w/abnormally viscous digest
How do we provide free gas bloat prevention & control?
If it’s chronic, a temporary rumenotomy…
Need to identify underlying cause…
Rumen fluid evaluation, oesophageal
endoscopy, reticular U/S, exploratory
laparatomy/rumenotomy
How do we provide frothy bloat prevention/control?
Grazing management/adaption diets
Poloxalene
(top dressing, mineral block, liquid supplement)
Ionophores
(monensin & lasalocid)
How do we incise the external abdominal oblique muscle in rumen fistulas?
horizontally
How do we incise the internal abdominal oblique & transverse abdominal mm. in rumen fistulas?
vertically
