L-Valine Overview
L-Valine is one of the three branched-chain amino acids (BCAAs) essential for animal growth,
muscle development, and nitrogen balance. As animals cannot synthesize valine, it must be
supplied through feed formulations.
Our L-Valine is produced according to Q/BHH001 feed-grade standards and shows excellent purity,
flow characteristics, and stability. It supports reduced crude protein diets, optimized amino
acid ratios, and improved feed efficiency across poultry, swine, ruminants, and aquaculture.
Other essential amino acids such as L-Lysine and DL-Methionine can be used together with L-Valine to optimize feed formulations.

Quality Assurance
Our L-Valine is manufactured following Q/BHH001 feed-grade specifications and undergoes
strict quality control for each batch.
Quality tests include:
• Purity and identification confirmation
• pH and specific optical rotation
• Loss on drying and residue on ignition
• Heavy metals and microbial safety (Salmonella)
• Batch consistency and full traceability
Each shipment is accompanied by an official Certificate of Analysis to ensure transparency,
reliability, and compliance with feed additive requirements.
Applications & Dosage
L-Valine is applied across a wide range of feed formulations to balance essential amino acids
and enhance protein utilization efficiency.
Typical inclusion (for reference; final dosage should follow nutritionist formulation):
• Poultry: 0.05–0.20% of complete feed
• Swine (weaners & growers): 0.05–0.25% depending on diet composition
• Aquaculture: 0.10–0.30% depending on species
• Ruminants: According to bypass-protected formulations
Using this amino acid allows reduction of crude protein levels while maintaining performance and reducing nitrogen emissions.
Product FAQ
1. What is L-Valine used for in animal feed?
L-Valine is used to balance essential amino acid profiles in feed formulations and support muscle growth, protein utilization, and performance in poultry, swine, ruminants, and aquaculture.
2. Why is L-Valine important in low-protein diets?
L-Valine helps maintain growth and feed efficiency when crude protein levels are reduced, allowing nutritionists to lower nitrogen emissions and optimize formulation costs.
3. Is feed-grade L-Valine suitable for all species?
Yes. Feed-grade L-Valine is commonly used for poultry, swine, ruminants, and major aquaculture species to improve amino acid balance and growth performance.
4. What quality standard does your L-Valine meet?
Our L-Valine meets Q/BHH001 feed-grade specifications and undergoes full COA testing for purity, pH, optical rotation, heavy metals, and microbiological safety.
5. What is the typical assay of feed-grade L-Valine?
Feed-grade L-Valine generally shows an assay between 98.0% and 101.5%, with most commercial batches—including ours—testing around 99% purity.
6. How is L-Valine used in feed formulations?
L-Valine is included at 0.05–0.30% depending on species and diet structure. It is normally added in premixes or direct inclusion to correct amino acid imbalances.
7. Can L-Valine be used together with Lysine and Methionine?
Yes. L-Valine is commonly used alongside L-Lysine and DL-Methionine to achieve ideal amino acid ratios and support efficient lean growth.
8. How should L-Valine be stored to maintain quality?
L-Valine should be stored in a cool, dry, well-ventilated place, away from heat and direct sunlight, to preserve stability and prevent moisture absorption.
9. What packaging options are available for L-Valine?
Feed-grade L-Valine is typically supplied in 20–25 kg kraft bags or woven compound bags with inner liners, ensuring moisture protection and safe transportation.
10. Does L-Valine improve feed cost efficiency?
Yes. By allowing reduced-protein diets and correcting amino acid deficiencies, L-Valine helps improve feed conversion and reduce formulation costs without compromising performance.
