Service Selection

Silage & Fermentation

Service Selection

Choose the path that matches the material you are testing and the decision you need to make. We organize our services the way producers and nutrition professionals actually work: by sample type, by feeding question, and by reporting need.

Forage Analysis

Silage & Fermentation

Service Selection

Hay, haylage, baleage, and fresh forage testing for nutrient quality, digestibility, and practical feeding value.

Silage & Fermentation

Silage & Fermentation

Silage & Fermentation

Corn silage and other ensiled forage testing with options that support preservation review and feedout decisions.

TMR Analysis

Commodity & Feed Ingredients

Silage & Fermentation

Delivered-ration testing to support consistency checks, troubleshooting, and feeding management.

Commodity & Feed Ingredients

Commodity & Feed Ingredients

Commodity & Feed Ingredients

Measured values for grains, byproducts, protein feeds, and mixed ingredients used in ruminant diets.

Mineral & Add-On Testing

Commodity & Feed Ingredients

Commodity & Feed Ingredients

Optional add-ons such as mineral panels, nitrate testing, and pH when your feeding question requires more detail.

Energetics, Efficiency & Reporting

Energetics, Efficiency & Reporting

Energetics, Efficiency & Reporting

Laboratory support for ration energetics interpretation, benchmarking, and reporting workflows.

Why Test With E3Ruminant Labs

Feed costs are too important to manage by appearance alone. Laboratory analysis helps you understand variation, compare lots, improve ration accuracy, support supplementation decisions, and document feed inputs for efficiency or sustainability-related workflows.

Practical Reporting Support

Better Feeding Decisions

 E3Ruminant Labs is built specifically for ruminant feed systems.  Our work is designed to help producers and advisors make better feeding decisions while keeping reports practical, clear, and useful.

Better Feeding Decisions

Practical Reporting Support

Better Feeding Decisions

Use measured values to compare forage lots, verify ingredients, and reduce guesswork in ration planning.

Clearer Benchmarking

Practical Reporting Support

Practical Reporting Support

Track feed quality and ration consistency over time so you can compare lots, seasons, and management changes.

Practical Reporting Support

Practical Reporting Support

Practical Reporting Support

Use laboratory outputs as a foundation for producer-facing summaries, internal benchmarking, and program-aligned reporting workflows.

How sample submission works

1. Choose your sample type

Select hay, silage, TMR, grain, or feed ingredient.

2. Choose your analysis package

Pick a package based on ration formulation, forage marketing, troubleshooting, or reporting needs.

3. Download the form and label your sample clearly

Include your contact information, sample ID, sample description, and requested analysis.

4. Package and ship promptly

Seal the sample securely and send it to the lab as soon as possible after collection.

5. Review your report

Use the results for ration decisions, benchmarking, troubleshooting, or reporting support.

Built for real-world forage and feed decisions

Our services are organized around the decisions producers and nutrition professionals make every day: what to feed, how to compare lots, when to supplement, how to troubleshoot performance, and how to document feed-related information for reporting purposes.

Service Categories

Forage Quality
Evaluate hay, haylage, baleage, and fresh forage for nutrient and feeding value.

Silage Review
Support feedout decisions and compare silage sources, storage units, and crop-year variation.

Ration Consistency
Use TMR analysis to verify what is being delivered and monitor dry matter shifts.

Ingredient Accuracy
Test grains and feed ingredients so ration inputs reflect measured values instead of assumptions.

From lab results to better interpretation

From lab results to better interpretation

Laboratory values are the starting point, not the end of the conversation. E3Ruminant Labs helps connect feed and forage analysis to ration energetics, feed-efficiency review, and producer-facing reporting support.


Important note

Some outputs used in efficiency or emissions-related workflows are modeled or inferred from measured laboratory values plus additional ration, intake, animal, or system assumptions. Reports should clearly distinguish measured values from calculated outputs.

Learn About Reporting Support

Helpful resources for better sampling and better decisions

Good reports start with good samples. Use our resource pages to improve sample collection, understand what your report means, and communicate results more confidently.

Sample Collection Guides


Practical guides for hay, silage, TMR, and ingredient sampling.

Report Interpretation Guide

Clear explanations of major feed values and how they are commonly used.

Producer Education

Short practical content on forage quality, ration consistency, and feed testing.
