11.12.24 - Enhanced Nutrition Report Features: KPS Indicators

As the industry continues to use Kernel Processing Score (KPS) at harvest and feedout to benchmark corn silage grain feeding value, we’ve added a Near Infrared Spectroscopy (NIRS) KPS Indicator on our nutrition analysis reports to better inform ration decisions.  

‘Likely above 70’ denotes a high probability for KPS at or above 70; alternatively ‘Likely below 70’ depicts the opposite. The 70% threshold has been a long-standing goal, and our current interpretive guidelines for standard KPS test results can be found and downloaded here. For samples likely below 70, producers should consider assessing KPS with traditional methods

This new indicator is available within our Comprehensive Nutrition Analysis (CNA) by NIR for corn silage. Read the Frequently Asked Questions here and try it out today!

10.22.24 - New Total Tract Fat Digestibility Tool

Fat supplements in dairy diets are expensive and there is likely a range in supplement digestibility. Thanks to collaborative research with the UW-Madison College of Agricultural & Life Sciences, we have a new tool to assess total tract fat digestibility (TTFD) in lactating dairy diets. TTFD cattle can be predicted with fecal fat, much like fecal starch has been used to project total tract starch digestibility. Read the details, guidelines, and benchmarks, here.

As the fall soil season begins, we're sharing a few reminders to ensure that your samples make it safely to the laboratory for analysis:

  • If placing loose samples into our dropboxes, please don't insert more than 20 soil samples. 
  • Please keep box weights within the 35 to 40 pounds at most so our drivers can safely pick them up
