Research has shown that ketosis (clinical and subclinical) affects 40 to 60% of dairy cows, at an average cost of $289 per case. Cows with ketosis not only produce less milk, but are more likely to develop other health related issues such as a displaced abomasum, fatty liver, and an increased chance of herd removal in the first 30 days. Traditionally, monitoring clinical and sub-clinical ketosis has been difficult and time consuming because most detection methods involve testing individual fresh cows on a weekly basis. However, thanks to new research done by the University of Wisconsin Dairy Science Department and School of Veterinary Medicine, under the leadership of Dr. Heather White, Tawny Chandler and Dr. Gary Oetzel, in cooperation with AgSource, your DHI milk sample can now be used to evaluate monthly ketosis prevalence in your herd.

AgSource's KetoMonitorTM, introduced on January 28, 2015 is a new, comprehensive tool that combines laboratory analysis and individual cow data collected on test day to provide producers with a report that will estimate a herd's ketosis prevalence. This report evaluates Early Fresh (5-11 DIM) and Overall (5-20 DIM) prevalence levels for 1st and 2nd+ Lactation groups. The KetoMonitorTM is designed to alert you to any changes that may have an impact on transition cow health, guide management and nutrition decisions and customize on farm blood testing protocols. Although it is not designed to be an individual cow test, it will also flag early fresh cows that are likely to have ketosis.

Block A: This report represents 2 tools. The overall herd (5 to 20 DIM) predicted ketosis prevalence (top of panel) should be used to monitor monthly prevalence to aid in guiding management and nutritional decisions. The number of fresh cows tested and the number of cows that freshened since the last DHI test is provided. Because milk testing is only once per month, not every fresh cow is tested for ketosis. Cows that are tested between 5 -20 DIM and predicted to have ketosis are listed on the back of the report.

Keto-BLOCK-B-web.jpg

Block B:
 Ketosis is expected to be more prevalent in cows in their 2nd or greater lactation. The overall prevalence of ketosis by lactation group (1st Lact and 2nd+ Lact) are provided for the current and 12 previous months.
 

Keto-BLOCK-C-web.jpg

Block C:
Monthly prevalence is provided for the current and 12 previous months for overall herd ketosis (5 to 20 DIM) and early fresh cow ketosis (5 to 11 DIM range). The total number of cows tested for each prevalence is noted in the table above the graph.

Block D: The ketosis prediction model is able to identify cows that are likely to have ketosis on the day of milk test. These cows may benefit from treatment for ketosis. Remember that this is not an exhaustive list of ketotic cows and some ketotic cows may not be flagged on this list due to the single time point testing. This list can help identify patterns in early ketosis onset; however this list does not indicate the day of ketosis onset. Because this is a single time point prevalence test, cows in the 12 to 20 DIM list may have actually become ketotic prior.

Block E: A listing of cows that are due to calve within 90 days from test day that were flagged as positive for Ketosis in one or more lactation prior. These cows are considered at higher risk for ketosis at calving and should be more closely watched.
