2017 FORAGE QUALITY

Despite a cooler spring, first cutting of forage began in late May, and extended into June. Protein and relative feed value (RFV) are down slightly in 2017 vs 2016, with ADF, NDF, and lignin averaging slightly higher. However, given the challenging weather condition this season, the quality of first cut forages is quite good, but somewhat variable.

Analyzing forages for nutrient content is useful in determining whether quality is adequate, and as a tool for proper ration supplementation. SGS provides many analytical packages to assess forage quality.

TESTING DDG'S

SGS routinely tests Dried Distiller’s Grains (DDGs) for LC’s and export. Common tests include, but are not limited to:

  • Crude Protein
  • Moisture
  • Ash
  • Crude Fat
  • Crude Fiber
  • Hunter L* Color
  • ProFat %
  • "Free from" live insects and molds

Contact the lab for more information on this testing.

PLANT TISSUE SAMPLING

When submitting plant tissue samples, please package in paper and submit a minimum of 200 grams of fresh material. This amount generally half fills a paper lunch bag, and is required to test all of the nutrients and also provides a more representative sample.

For early season testing, the whole plant can be sampled, cutting off just above the ground and exercising care so as not to contaminate the tissue with soil. A rule of thumb for mid-season is to sample the most recently fully-matured leaf:

  • Usually the 5th trifoliate from the top of a soybean plant
  • Corn testing should have the ear leaf sampled
  • For fruit crops, the last two weeks in July is the optimal period for testing leaf samples 

SAMPLING SUPPLIES

SGS gladly provides sample supply packaging, and suggests a 3 month supply as a reasonable amount to keep on hand. We can provide soil sample boxes or bags, plant tissue bags, water bottles for nutrient testing (greenhouse, livestock, and irrigation) and microbiological testing, manure jars, and feed/forage bags. Please contact the lab for more details, or submit this form to have supplies sent to your location.
