6.21.17 - Forage crop quality trends vary across the US

The latest nutritive quality trends report composed from our analysis data and expert team review suggest varied results.  Here is a quick overview of our insights. Download the report here.

Eastern US

    • Corn silage: quality is relatively stable now that producers are well into feeding '16 corn silage
      • The crop's TTNDFD looks to be up slightly over '15, likely due to drought in much of the region
    • Hay & Haylage:
      • Protein is down but fiber content remains steady
      • NDFD30 and TTNDFD have modestly increased month over month and relative to '16. Expect more milk based on these trends.

Midwestern US

    • Corn silage: As we’ve witnessed in the past, there is more grain in '16 relative to '15 silage
    • Hay & Haylage: first cutting is rolling in
      • Slightly more fiber in early '17 hay and haylage, relative to '16
      • NDFD appears to be up from ‘16

Western US

    • Silage: Small grain silages look to be up in starch and grain, diluting out the fiber
    • Hay (mostly):
      • Hay TDNs trending down, possibly due to substantial rain, delayed harvest or rained on hay, or disease pressure and leaf losses

12.13.16 - Feed analysis trends and depleted animal health are highlighting detrimental feed quality; TMR Hygiene Rock River Laboratory is here to help

The Rock River Laboratory technical nutrition team is observing concerning levels of anti-nutritional factors within Total Mixed Rations (TMRs). These observations from sample analyses, combined with ongoing calls regarding reduced cattle performance, sick animals and even some fatalities have driven the creation of the TMR Hygiene Diagnostic package. This new analysis package has been created to help both Rock River Laboratory’s nutritionist partners and their customers quickly and efficiently identify and combat the detrimental effects of the broad spectrum of anti-nutritional (mycotoxins, nutrition, bacteria and stress – Figure 1) prevalence across the US. The Midwest corn crop and harvest was challenged by the likes of stalk and ear rots (molds), yeast, and mycotoxins (Vomitoxin (DON) and other toxins). Rock River Laboratory is recognizing heavy anti-nutrition factor concentrations within many corn based feeds and TMRs.  These factors combined with other negative nutrition (i.e. lesser than ideal rumen starch digestion) and/or stress factors may compromise cattle health and performance.

Nutritionists and producers suspecting any opportunities in this realm should consider the TMR Hygiene Diagnostic package, which combines several items from the Rock River Laboratory portfolio to assist in narrowing down the culprits and to help lead users to the root of these problems – hopefully in time to proactively avoid animal health challenges. The new TMR Hygiene Diagnosis package includes: 

  • Mold, yeast, and Vomitoxin (DON) count
    • Mold identification
  • Clostridium perfringens (C. perfringens) and other enterobacteria count
  • TMR Nutrient Analysis
  • Wet chemistry Rumen Starch Digestion 

Package cost: $140 ($50 off the list price)

Those interested in running this analysis on samples should write “TMR Hygiene Diagnostic” on their Feed Analysis Request Form. FeedScan users can select ‘TMR Hygiene Diagnostic’ under the Mold/ Toxin heading within the app. 

Results will be reported within 10 business days following the samples receipt. Upon receipt, nutrition consultants and producers who would like further support are welcome call Rock River Laboratory’s technical nutrition team.
