Bedding Frequency
Critical to decreasing
bacteria numbers in stalls
Goal
Conclusion
Controlling exposure to environmental
pathogens between milkings is
important for udder hygiene.
Bedding material must be properly
maintained to reduce exposure,
prevent udder infections and reduce
SCC.
Bedding materials must be carefully
selected.
Clean!Clean!Clean!
Milkers must wear gloves!
And Keep them Clean!
Keep Milking Units Clean
Keep cow platforms
Clean
GLOVES

Teat Dipping
Primary Reason to Teat
Dip is to Remove the
Milk Film Left on the Teat
After Milking With a
Layer of Germicide
Culturing Programs
Need appropriate sample collection
and storage
Must have a plan to utilize information
