rumen fluid analysis tests (7)

• color

• consistency

• odor

• plt

• anaerobic bacteria reduction test

• protozoa

• gram stain

indirect milk sample techniques (2)

• black plate

• California mastitis

black plate technique look for

homogenisity

california mastitis technique detects (2)

• inflammation

• increase in wbc

direct milk sample techniques (4)

• BAP culture

• mycoplasma culture

• standard plate count

• coliform plate count

rumen fluid normal color

range from grey to green brown

abnormal rumen fluid colors and causes (2)

• milky grey - acidosis

• black green- stasis

normal rumen consistency

• slightly viscous

very viscous rumen consistency means?

• the sample may have been contaminated with large amounts of saliva

rumen consistency notes on lab form

• descirbe viscosity (watery, slighly viscous, moderately, marked)

• presence of bubbles that don’t dissolve

rumen consistency bubbles indicate what

frothy bloat

abnormal rumen odor

range from acidic/sour smell to rotten smell

normal rumen ph

• 5.5- 7.0

rumen ph <5.5 indicates

acidosis

rumen ph 7-8 indicates

recent rumen stasis

rumen ph >8 indicates (3)

• prolonged rumen stasis

• urea toxic effects

• saliva contamination

anaerobic bacteria reduction normal clear time in cattle

blue color disappears in 2-6 minutes

anaerobic bacteria reduction test clear test time > 10 min in cattle indicates

inadequate functioning bacteria

normal amount of protozoa in cattle seen on lpf

40

highest percent of organisms in cattle seen in gram stain

gram negative organisms

permanent id of all treated animals (3)

• ear tag

• tattoo

• freeze brand
