Offering Milk Quality Programs for Producers

Why focus on milk quality and do cultures in-house?
• New service you can provide – Generates on-farm consulting
opportunities• Win/win for you & client
– Improving milk quality improves profits
• Allows you to make informed treatment recommendations– Pathogen-specific protocols
Milk Quality & Udder Health
Individual cow level– What’s causing
the infection?– Does it need to be
treated?• If so, what drug
and for how long?– Does she need to
be handled differently?• Ex – contagious
pen
Herd level– What bugs are the
major players?– What risk factors
are present? • Environmental?• Equipment?• Milking
procedures?– How are the cows’
natural defenses?• Teat ends?
Bacteriology
Data Retrieval & Analysis
Field Observations
& Data Collection
Milk Quality Programs
Services our lab provides• Individual cultures with specific
treatment recommendations• Bulk tank cultures, bedding &
towel cultures, bacterial counts (ex. Colostrum, pasteurized waste milk)
• Mycoplasma referred out at this time
enhanced mycoplasma surveillance by pooling clinical samples (max. 10/pool)
On-farm Services Part I “People & Cows”
• Parlor Analysis– Milking routine
• Order, timing, consistency– Milk flow (Lactocorder)– Teat-dip coverage– Hygiene (cows, teat ends, towels,
units)– Unit alignment
• Record any changes made since last visit (teat dip, type of liner, personnel, etc)
Equipment Needed:–Stopwatch–Headlamp (if scoring teats)–Pens, forms &/or hand-held units–Lactocorder if doing flow-analysis–Camera
Your very best “big picture” observation skills
Herd scoring• Teat end scoring• Hygiene scoring
• *Record current pen-definitions each time you score cows! – (i.e. first calf heifers, late lactation cows,
Staph / mastitis pen, etc)
On-farm services Part II“Machinery”
• Milking equipment analysis– NMC protocol– Stopwatch, flowmeter, Vacuum
Recorder• Milk system cleaning analysis
– NMC protocol– Important if troubleshooting high
bacteria count problem
On-farm Services Part III“Training”
• Sterile sample collection• CMT use• Milking procedures
Data Analysis• Summarize findings from Parlor
Analysis– Compare current scores with previous
scores• Download regular monitoring
reports for vet’s herd health visit• Summarize culture data for vet • Download BTSCC & bacteria data

Using the data to look for pathogen trends in DC305
• EGRAPH feature in DCOMP– Select CULTURE event– Check box for “Use Scatter” – Choose “Event Date” for X-axis– Choose “Result/Remark” for legend
Using the data to look for trends
1st calf heifers – who were not yet receiving J5 prior to calving
Using trends to identify opportunities
Putting it all together: annual herd reviews
Successful programs are herd-specific
• Need to find out what the dairy’s goals &/or concerns are– Problem-oriented (Ex. Eliminate
contagious mastitis)– Quality-oriented (Ex. Reduce BTSCC
to achieve the next tier in quality payments)
– Efficiency-oriented (Ex. Increase parlor throughput)
Progress made – contagious mastitis

Staph Aureus Cultured from 2004 - 2007
St Aureus
Example from herd review
The Economics of Culturing
• 522 cases cultured last year– Based on your results:
• 18% Treat• 36% Maybe treat (case by case)• 45% No treat
• If 50% of the “Maybe”s treated:– 190 Treated– 332 Not treated
Cost of culturing = $5350.50
Example from herd review
The Economics (cont’d)…..• Drug cost for treating 1 cow for 3
days with Spectramast LC = $9.21• Milk discard for each treated cow =
6 days (3d tx + 3d withdrawl)• Assuming avg 70 lbs production for
mastitis cow & milk price $18.78/cwt: cost of milk discard for tx’d cow = $78.88
Example from herd review
“Am I getting a return on my investment in
culturing?”“No culturing - treat all mastitis”
– Cultures = $0– Drugs = $4808– Milk discard = $41,173– Total cost = $45,981
“Culture & treat based on results”– Cultures = $5351 – Drugs = $1731– Milk discard = $14,822– Total cost = $21,904
Money saved from culturing in 2007 = $24,077
