Lower your SCC - Advice from Dr. Jeff Reneau:

Cow hygiene score card.  A University of Minnesota study showed that in herds where environmental mastitis predominate, hygiene of the lower rear legs and udder correlated to SCC.  Cows with higher cow hygiene score also had a higher SCC.  The average hygiene score for rear legs and udders for cows in this study was 2.95 (on a hygiene score scale of 1-5 with 1 being spotlessly clean and 5 being very dirty) and the average SCC for the 1191 cows studied was 405,000.  For the cows in this study, every 1 unit score improvement in hygiene resulted in a 50,000 reduction in SCC.  Using the cow hygiene score card, also found on the above mentioned website, you can determine the potential SCC impact of keeping your cows cleaner.

 

 

Cows are dirtier in early lactation.  Unfortunately this is also the time when they are most vulnerable to getting new mastitis infections because their immune system may be somewhat depressed.  Therefore, more intense bedding and stall management should be given to maintain clean and dry stalls for close-up dry cows, fresh and early lactation cows.

 

University of Minnesota Diagnostic Lab culture records indicate that most of the mastitis in Minnesota dairies is coming from environmental pathogens.  That is why the bottom line for reducing Minnesota BTSCCs boils down to hygiene.  More effort in keeping cows cleaner and more effort in cleaning teat surfaces prior to milking will always pay off in lowering BTSCC.  How about it?  Let’s all initiate a “spring cleaning” in a concerted effort to get Minnesota’s SCC back on track.

 

 

Mastitis Culturing

 

With warmer weather coming there is often an increase in the incidence in mastitis and subsequent Bulk tank Somatic Cell Counts. Many Minnesota DHIA Field Representatives have had training in proper sampling techniques for taking Bulk Tank and individual cow samples for mastitis culturing. They will be happy to assist you if you are interested in having some cultures tested to determine what organisms are causing your herd problems.

 

Here are some things to keep in mind regarding mastitis cultures:

·                    Avoid contamination! The best time to take individual cow samples is after prepping the cow, but before putting the unit on. Clean teat ends thoroughly while prepping and then use an alcohol pad to scrub the teat end before taking the sample. Samples must be taken directly from the teat—milk going through the claw or hoses will be contaminated.

·                    Vials must be sterile! Vials can often be obtained from your milk hauler for a few samples, or get them from the lab that will do the culturing. DHIA testing vials will not work because of the preservative in them. Avoid touching the inside of the cap and keep dust and other contaminates out of the sample.

·                    Samples must be cooled immediately, and frozen as soon as possible. They must be packed to remain frozen while shipped to the lab.

·                    Five days worth of samples can be taken and combined for Bulk Tank cultures to give a more representative result than just one day.

·                    Your Field Representative has more detailed information that they can print out for you, including the cost of cultures done at the Stearns DHIA lab or the University of Minnesota.

 

RFID Tags available from DHIA

The bovine industry has settled on Radio Frequency chipped eartags as the best management practice for the National Animal Identification System (NAIS).   Minnesota DHIA offers the tags.  You can choose RFID tags from Fearing (Digital Angel), and All Flex.  All Flex RFID tags are $2.60 each, plus shipping and sales tax.  Digital Angel RFID tags are $2.15 each ++.  Please have your Premise ID ready when you call to order tags.

 

 

You can order RFID tags in tandem with management tags.

 

 

Tag should be inserted in the left ear, no closer than 1/3 of the ear from the head, between the middle two cartilage ribs, with numbers on the inside

Cows for sale is a service of MN DHIA.  Members can advertise for just $2.50 per animal with a maximum of $50 per herd (good for 60 days). Cows are listed on our website, on the Field Rep updates, and in this newsletter.  Please contact Nancy Zander at 800.827.3442 to list "Cows for Sale".
