Hydrolyzed Protein Powder — Cattle Bone, ≥ 90% Crude Protein
A collagen-derived protein input at ≥ 90% crude protein and ≥ 80% total amino acids, glycine and proline rich, dissolving at 99% for animal feed, pet food, aquaculture and agricultural use.

What This Product Is
Protein Powder is the one product in the range that does not start as feather keratin. It is hydrolysed cattle bone, which gives it a collagen amino acid distribution rather than the keratin distribution of the amino acid grades.
Crude protein is specified at ≥ 90% and total amino acids at ≥ 80%, with crude ash ≥ 9%, crude fat ≥ 0.5%, moisture ≤ 6% and pH 5 to 7.5 in a 1% solution. Water solubility is 99%, so it mixes into liquid feeds, premixes and process lines without leaving sediment in dosing equipment.
The profile is dominated by glycine at 23.98% and proline at 12.61%, with valine 11.19% and glutamic acid 9.35% — the signature of bone collagen and the reason the powder is used as a palatant base as well as a protein source.
What You Get
- ≥ 90% crude protein with ash, fat, moisture and pH all declared on the specification
- Glycine 23.98% and proline 12.61%, the collagen distribution valued in feed and palatant applications
- Hydrolysis breaks the protein into short peptides and free amino acids for efficient absorption
- 99% water solubility for clean mixing into liquid feeds and premixes
- Traceable cattle bone raw material processed under controlled hydrolysis
Who Buys It
- Animal feed and premix manufacturers
- Pet food producers formulating palatants
- Aquaculture feed formulators
- Fermentation plants needing a protein substrate
- Agricultural formulators wanting a protein supplement rather than an amino acid concentrate
What It Fixes
- Protein inputs sold without a stated amino acid distribution
- Powders that only partly dissolve and leave sediment in dosing lines
- Undeclared ash and fat ranges that make least-cost formulation guesswork
- Palatant sourcing that changes character from batch to batch
How It Is Made And Supplied
- Source: hydrolysed cattle bone
- Controlled hydrolysis under the same process discipline as the amino acid grades
- pH 5 to 7.5 in 1% solution — closer to neutral than the amino acid grades at pH 4 to 6
- Crude ash ≥ 9% and crude fat ≥ 0.5% declared on the specification
- Moisture ≤ 6%
- Batch-specific COA with every shipment; TDS and SDS available
Technical Data

Typical Use Rates
Rates vary by crop, growth stage and formulation target. Our team provides crop-specific recommendations on request.
- Animal feed premix, dosed per formulation target
- Pet food palatant or protein base, dosed per formulation target
- Aquaculture feed, dosed per formulation target
- Agricultural protein supplement at 3 – 5 kg per hectare
- Fermentation substrate, dosed per process requirement
How It Compares With The Alternatives
| Against the amino acid grades | These are feather keratin hydrolysates sold on free amino acid content for crops. This is a cattle bone collagen hydrolysate sold on crude protein for feed and agriculture. |
|---|---|
| Against a plant protein meal | Solubility here is 99% and the protein is already hydrolysed into short peptides and free amino acids. |
| Against an undeclared bone meal | Ash, fat, moisture, pH, crude protein and total amino acids are all specified, and the batch COA reports against them. |
| Against a synthetic palatant | The palatability comes from the collagen amino acid profile itself rather than from an added flavour system. |
From Sample To Production Batch
Step 1
Set the inclusion from the crude protein and amino acid target of the finished feed.
Step 2
Dissolve into liquid feeds with agitation; solubility is 99%, so a short mixing time is enough.
Step 3
Account for the ≥ 9% crude ash in the mineral balance of the finished formulation.
Step 4
Check the pH 5 to 7.5 window against the rest of the process line.
Step 5
Store sealed and dry; moisture is specified at ≤ 6%.
Step 6
Keep the batch COA for traceability in the feed production record.
Product, Packaging And Application
Questions About Protein Powder
What is the raw material?
Hydrolysed cattle bone. It is the only product in the Everwell range not made from duck feather protein.
Why is the glycine content so high?
Glycine at 23.98% and proline at 12.61% are characteristic of bone collagen, which is what this powder is hydrolysed from.
Can it be used on crops as well as in feed?
Yes. It is listed for agricultural protein supplementation at 3 to 5 kg per hectare, alongside its feed, pet food and aquaculture uses.
How soluble is it?
99%, against 100% for the amino acid grades. That is enough to mix cleanly into liquid feeds, premixes and process lines.
Is a Eurofins report available for this product?
The April 2026 Eurofins reports cover Amino Acids 45, 50 and 80. For Protein Powder the figures come from the batch COA.
What documentation ships with it?
A batch-specific COA with every shipment, with TDS and SDS available on request.
