Forage testing is laboratory analysis of hay, silage, and other forages that measures nutrient content—including protein, fiber, energy, and...
Forage testing is fundamental to precision dairy nutrition. Because forages comprise 50-70% of dairy rations, their nutrient content determines supplementation needs. Small differences in forage quality translate to large differences in production costs and cow performance.
Standard forage analyses include dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and calculated energy values (TDN, NEL). These basic measures enable ration balancing for protein, fiber, and energy. Many operations also test for lignin, starch, ash, and fat.
Advanced analyses add value for intensive management. NDFD (NDF digestibility) predicts fiber utilization better than NDF alone. In vitro or in situ digestibility measures actual degradation. Fermentation analyses for silages (pH, organic acids, ammonia) indicate preservation quality. NIR-based amino acid predictions enable metabolizable protein balancing.
Sampling technique determines result accuracy. Proper sampling represents the entire lot—multiple core samples from bunker faces, bales from throughout the lot, or grab samples composited over multiple deliveries. Poor sampling makes even precise laboratory analysis meaningless.
Testing frequency depends on forage uniformity and management intensity. Corn silage from a single bunker may need testing once; variable hay lots need testing with each new delivery. High-producing herds often test forages monthly or more frequently to track quality changes.

Buying Considerations
Important factors to consider when evaluating What Is Forage Testing for Dairy Farms?:
- Laboratory Accreditation: Choose labs certified by NFTA (National Forage Testing Association) or participating in proficiency testing programs to ensure accurate, consistent results across time and different facilities.
- Turnaround Time: Standard turnaround is 3-5 business days, but premium services offer 24-48 hour results. Consider faster service during harvest when timely decisions impact silage management.
- Testing Parameters: Basic panels ($25-35) include DM, CP, ADF, NDF. Comprehensive panels ($45-65) add sugars, starch, minerals, and digestibility. Mycotoxin screening adds $30-50 per sample.
- Sample Handling Requirements: Proper sampling technique and shipping procedures are critical. Some labs provide sampling tools and prepaid shipping boxes, while others require specific sample preparation protocols.
- Reporting and Integration: Modern labs offer online portals, mobile apps, and direct integration with nutrition software like AMTS, CPM-Dairy, or NDS Professional for seamless ration formulation.
Evaluation Questions
Key questions to consider when evaluating What Is Forage Testing for Dairy Farms?:
- What analyses does our nutritionist need for ration formulation?
- How often should we test each forage type?
- What is proper sampling technique for our forage storage?
- Do we need standard turnaround or rush results?
