Silage is a high-moisture, fermented forage that plays a vital role in the diets of dairy cows, beef cattle, and feedlot animals. When harvested, stored, and fed properly, silage provides excellent energy, fiber, and digestibility. However, not all silage is created equal. Grading silage helps producers assess nutritional value, fermentation quality, and suitability for various livestock applications.
At Barr-Ag, we grow and supply premium barley and corn silage using sustainable practices and precision harvesting. All of our silage products are tested regularly through internationally recognized laboratories to ensure consistent nutritional quality and reliable performance for our customers across North America and abroad.
How Is Silage Evaluated?
Silage quality is evaluated based on both nutritional content and fermentation characteristics. It is determined through laboratory analysis that includes:
- Dry Matter (DM%) – Indicates how much of the silage is actual nutrient content compared to water. For reference, ideal DM for corn silage is typically around 32 to 35% and for barley silage around 35 to 40%. Our dehydrated silage product has a DM of greater than 88%, ensuring a concentrated nutrient source.
- Crude Protein (CP%) – Reflects protein levels. Barley silage typically ranges from 10–14%, while corn silage is lower (around 7–9%) but higher in energy.
- Neutral Detergent Fiber (NDF%) – Impacts intake. Lower NDF generally improves consumption.
- Starch (% of DM) – One of the most important measures in grain silage. Corn silage typically contains more than 30% starch (DM basis), while barley silage averages around 15–18% (DM basis).
- Total Digestible Nutrients (TDN%) – Measures energy. Corn silage has a high TDN (70–74%) due to starch content. Barley silage ranges from 64–68%.
- pH Level – Indicates fermentation quality. Ideal pH is 3.8–4.2. Higher pH may signal poor fermentation or spoilage.
- Lactic Acid and Volatile Fatty Acids (VFAs) – Healthy fermentation results in high lactic acid and minimal butyric acid.
Factors That Influence Silage Quality
Several key factors affect the final quality and grade of silage:
- Harvest Timing
- Corn silage should be harvested at ⅓–½ milk line for optimal starch and digestibility.
- Barley silage is best cut at soft dough stage for maximum nutritional value.
- Chop Length
A proper chop length (19mm to ¾ inches) ensures good compaction and minimizes sorting at the feed bunk. - Packing and Storage
Properly packed and sealed silage minimizes oxygen exposure and encourages strong fermentation. - Moisture Level
Moisture that’s too high leads to seepage and poor fermentation. Too dry, and it may not pack well. - Hybrid or Variety
Some corn and barley varieties are bred specifically for silage and offer improved fiber digestibility or starch content.
Why Silage Quality Matters
Feeding high-quality silage results in:
- Increased milk yield and butterfat in dairy cattle
- Higher weight gains and feed efficiency in beef cattle
- Improved animal health and fewer digestive problems
- Reduced need for supplemental grain and protein
On the other hand, poor-quality silage can lead to:
- Spoilage and feed refusal
- Acidosis or digestive disorders· Acidosis or digestive disorders
- Increased feed costs due to nutrient deficiencies
Matching the right quality of silage to your herd’s needs ensures your feed investment delivers the best return.
