  1. Milk Quality Management Services from AgSource Jill A. Makovec, MS AgSource Cooperative Services

  2. Variety of Services Available • Udder Health Management Summaries • Culturing • Bulk Tank Cultures • Individual Cow Cultures • Collaboration with Milk Money Program • WisGraph

  3. Mastitis Treatment v. Control • Current mastitis mentality is treat or cull • Less focus placed on managing the problem(s) • Bacteria known to cause mastitis infections found in 3 main areas • Udder • Teat Skin • Incubating in milking system

  4. Milk Quality Troubles • Bulk tank or weighted average SCC over 200,000 • Dumping over 0.5% of milk in a year • More than 1-2 clinical mastitis cases per month per 100 cows • Research shows low SCC herds have as much clinical mastitis as high SCC herds

  5. Managing Udder Health • Identify problem cows in the herd • Individual cow SCC information • Udder Health Management Cow List • Identify problem pathogens • Bulk Tank Cultures • Individual Cow Cultures • Monitor progress • Udder Health Management Summary • Udder Health Management Cow List

  6. How Does AgSource Increase Member Profits? • In WI, AgSource cows average 21,470 pounds of milk • In WI, all cows average 17,367 pounds of milk, 24% difference • In WI, all non-DHI cows average 13,627 pounds of milk, 58% difference • At $13.00 milk, equals over $1,000 extra income

  7. About SCC… • All cows in upper Midwest average 338,000 SCC in 2002 • AgSource cows average 318,000 SCC in 2002, 6% difference • Most of our members use our services for SCC • Bottom line, we haven’t done nearly the job for members on SCC we have on production

  8. Mastitis and Somatic Cell Counts Example herd: 225 cows milking 20,000 pounds each @ $11.00/cwt milk • Actions: AgSource SCC information, mastitis records, milker training, bulk tank and individual cow cultures for all cows • Results: $1.08/cwt. In extra SCC premiums & +8 pounds of milk/cow/day • $120,870 additional revenue, $537/cow • AgSource costs = $26/cow, 20:1 ROI

  9. Variety of Services Available • Udder Health Management Summaries • Culturing • Bulk Tank Cultures • Individual Cow Cultures • Collaboration with Milk Money Program • WisGraph

  10. Udder Health Management Summary • Block A – Herd information • Block B – Linear Score v. SCC • Block C – Comments • Block D – High Somatic Cell Count Cows • Block E – Linear Score Distribution • Block F – Current profile by lactation group • Block G – Previous 3 tests profile by lactation group

  11. Block B: Linear Score Conversion • SCC is converted to LnSc • Useful to show trends and milk loss • Less than 4 = Uninfected • Greater than 4 = Infected • First lactation cows lose 200 lbs/unit increase • Later lactation cows lose 400 lbs/unit increase

  12. Block B

  13. Block D: High Somatic Cell Cows • Signifies cows with new or current infections • Lactation and DIM • Lactation average LnSc • Current SCC • % of Total Bulk Tank SCC • Lists cows over 200,000 SCC • Contagious infected cows will stay on list • Environmental infections will change position

  14. Block D

  15. Block E: Linear Score Distribution • Distribution of LnSc for past several tests • Allows monitoring of progress • Estimated Infection Rate • % new identifies percent of the herd newly infected • % high identifies chronic cows • Estimated milk loss

  16. Block E

  17. Block F & G: Profiles • Identify milk quality problems by lactation group and stage of lactation • First lactation v. later lactation cows • Infections occurring during the dry period or later in lactation • Shows how past udder health practices have affected infection status

  18. Block F&G

  19. Block H: Av LnSc by Lact Group • 13-month snapshot of where the herd has been • Assess the extent of mastitis infection in your herd by lactation group

  20. Block H

  21. Block I: % LnSc greater than 4 • Measures the infection status of the herd • Prevalence of mastitis infection • An achievable goal for % Somatic Cell Linear Score greater than 4.0 is less than 15 % of your herd

  22. Block I

  23. Block J: Weighted Ave SCC • Represents what the bulk tank somatic cell would be for all cows tested • Seldom agrees with bulk tank SCC • Rounding • Meter errors • Cows on test but withheld from bulk tank

  24. Block J

  25. Block K: Ln Sc Quadrants • Comparison of this month's and last month's linear score on a cow basis. • Zone A: Cures • Zone B: Chronic Cases • Zone C: Uninfected • Zone D: New Cases • Used to determine the herd udder infection dynamics • Avoid large proportion of cows in zones B and D

  26. Block K

  27. UHM Recap • Long term solutions is a 2 year process • UHM Summary identifies current udder health of the herd • Identifies past trends in milk quality • Helps determine sources of infections • Affordable way to manage milk quality, improve udder health, and increase profits

  28. Variety of Services Available • Udder Health Management Summaries • Culturing • Bulk Tank Cultures • Individual Cow Cultures • Collaboration with Milk Money Program • WisGraph

  29. Culturing – An aid to mastitis control • Based on limited scientific data • Does provide 2 types of information • Presence or absence of a bacterial group • Identification of predominant bacterial groups • Gives numbers for bacteria present relative to goal levels • Assesses teat end condition and equipment hygiene • Monitor progress of mastitis control

  30. Culturing Strategies • Bulk Tank Cultures • Surveillance • Individual Cow Cultures • Culture subclinical cases • Take a sample from clinical cases before treatment • Culture if necessary • Fresh Cow screening based on CMT results • Fresh Start Program

  31. Bulk Tank Cultures • BTM cultures are an indication of mastitis prevalence in the herd • Useful for surveillance, management and treatment decisions • Not a substitute for determining infection incidence based on quarter milk samples

  32. AgSource Bulk Tank Culture

  33. Culture Results

  34. Pathogen comparison

  35. Frequency of Culturing • More often BTM is sampled, more useful the information • Samples should be taken over consecutive days • Use caution on results from a single sample • Samples should be taken monthly to quarterly, depending on herd size and current events

  36. Initial Review • First question • Is the sample positive for contagious organisms? • Staph aureus • Strep agalactiae • Mycoplasma sp. • Presence of these organisms often indicates an infected quarter • Negative results do not necessary mean the herd is negative for these pathogens

  37. Additional Review • Second Question • What are the predominant bacterial groups? • Typically a mixture • Any isolate could be from an intramammary infection • However, this is dependant on the bacteria • Coliforms and Environmental Streps are commonly found in other sources • Milking wet udders • Organic soil in milk lines • Cracked inflations • Inadequately heated wash water • Inadequate cooling of milk

  38. Culturing Individual Cows • Benefits • Identify cows infected with contagious mastitis • Suggest appropriate management practices • Assess treatment protocols • Affect treatment decisions • Drawbacks • Lag time for results to affect treatment decisions • Labor and cost • Ability to manage the data

  39. Individual Culture

  40. Treatment Decisions • In the past, treatment was based on severity of infection • Not as effective as possible • More effective decisions based on culture results • More information from cultures • Culture based treatment decisions geared for subclinical infections

  41. Variety of Services Available • Udder Health Management Summaries • Culturing • Bulk Tank Cultures • Individual Cow Cultures • Collaboration with Milk Money Program • WisGraph

  42. Milk Money Program • Team approach to milk quality • Meets monthly for 4 months • Identifies critical factors and helps farm make action plans • Funded through WMMB and supported by UW-Extension

  43. Milk Money Program Update • Through Spring 2004 • 113 or 180 farms returned forms from 1st and last meetings • 62% achieved milk quality goals • 99% agreed teams were useful • 83% planned to continue team meetings

  44. Milk Money & AgSource • Program Benefits include 3 FREE Udder Health Management Summaries • Sponsored by AgSource • Regional Vet Meetings • Feature mastitis solutions and the Milk Money Program

  45. Variety of Services Available • Udder Health Management Summaries • Culturing • Bulk Tank Cultures • Individual Cow Cultures • Collaboration with Milk Money Program • WisGraph
