Enhanced Cow Page in Production

The new cow page has now been out for about a month. You will note the color production graphs for each lactation and Inbreeding Coefficients on the cow, sire, dam, maternal and paternal grand sire. The data collection rating is coming soon from USDA. Barn Name of the calf is also being printed in the calving section, as it was provided on our old cow page a few years ago. To enroll in the cow page option, please visit with your Field Rep on sample day. Cost is just one cent per cow.

What’s the Inbreeding Coefficient?

The inbreeding coefficient is a measure of relatedness between ancestors. Inbreeding coefficients greater than 6.25 tend to result in some loss of productivity as measured by greater death losses, losses early in life, reproductive problems, slower growth rate and smaller mature size.

Attention: Scout Users

If you are interested in a little help on farm with your Scout program, your Field Rep has recently learned some of the key features in changing the vet list and other reports. If you are interested in making minor changes or want to learn more about recording Johne’s and other Health Events, just ask your Field Rep!

Johne’s Update: National Animal Health Monitoring System 2007 Survey

It is estimated that 1 in 4 herds has over 10% of the cows infected with Johne’s.
Johne’s was isolated from at least one environmental sample on 68.1 percent of operations, and prevalence increased with herd size.

Minnesota Board of Animal Health estimates that a 100 cow herd with a 10% level of infection can lose over $20,000
each year because of Johne’s Disease

*Minnesota DHIA Stats on Johne’s Testing*	*Summarizing Johnes Test Negative Program herds*
3.6% Positive in 2006	*in Minnesota*
4.7% Positive in 2007	• 1663 herds enrolled in MN (#1 in U.S.)
5.4% Positive in 2008	• 10% of herds<50 participate
4.9% Positive in 2009	• 50% of herds>500 participate
	• 31% of MN dairies participate
	• 60% of herds sending in milk had at least one positive cow

Johnes Milk ELISA is 55% Sensitive (catching just over half of the positive cows) and 99% Specific (99% of truly non-diseased cows will test negative)

Ask the Experts SCC questions

How soon after I remove the milker from a cow do I need to dip her?

Of course as soon as possible is best, but for all practical purposes getting the teat dip on within a few minutes after the milking unit has come off and before the cows leaves the parlor or lies down in her stall is fine. Dr. Jeff Reneau, University of Minnesota
