Feed Additives We Supply

Feed Grade Glycine:White crystalline powder, 98.5–101.5% assay. Suitable for poultry, swine, ruminant, aquaculture, compound feed, and premix formulations. Key parameters: pH, loss on drying, residue on ignition, sulfate, heavy metals, arsenic.

Choline Chloride:Available in 50% and 60% specifications, with corn cob or silica carriers. Key buying factors: choline chloride content, carrier type, moisture, trimethylamine, particle size, handling, packaging.

L-Valine:Essential amino acid for feed formulations. Focus on assay consistency, physical form, formulation compatibility, and reliable repeat supply.

L-Lysine:Important amino acid for animal nutrition and compound feed. Evaluate by product form, assay, moisture, physical characteristics, feed formulation needs, packaging, and supply volume.

L-Lysine Sulphate:Alternative lysine option for different nutritional and cost considerations. Selection based on actual feed formulation, nutrient contribution, and applicable product specification.

Selection Guide

Product	Role in Diet	Key Species	Typical Function
Feed-grade L-Lysine (HCl / free base)	First-limiting AA	Swine, poultry	Lean growth, FCR, lower crude protein
L-Lysine Sulphate	Lysine source (lower Lys %)	Swine, poultry	Cost-efficient lysine supply
L-Valine	Next-limiting branched-chain AA	Swine, poultry	Growth, immune resilience, low-protein diets
Feed-grade Glycine	Non-essential but rate-limiting AA	Aqua, young animals	Growth, stress resistance, feed intake
Choline Chloride (50/60%)	Lipotropic / methyl donor	Poultry, swine, aqua, ruminant	Liver health, growth & survival, nerve function

Species application guide

Species	Primary Products	What They Support
Poultry (broiler / layer)	L-Lysine, L-Valine, Choline	Growth rate, FCR, egg production, liver & nerve health
Swine	L-Lysine, L-Lysine sulphate, L-Valine, Choline	Lean gain, low-protein diets, gut & liver health
Aquaculture	Glycine, Choline, amino acids	Growth, stress/osmoregulation, survival
Ruminant	Choline (protected forms), amino acids	Milk performance, liver function [confirm protected formats]
Young / neonatal	Glycine, amino acids	Development where synthesis is limited

The Actual Mechanism Of Action Of Feed Additives

01/

Amino Acid Supplementation:Ingredients such as L-Lysine, L-Lysine Sulphate and L-Valine can be used to complement amino-acid profiles in formulated feeds.

02/

Nutritional Support:Glycine and Choline Chloride serve different nutritional roles and should be selected according to the animal species, feed formula and intended nutritional objective.

03/

Premix Compatibility:A feed additive must distribute consistently throughout the premix or finished feed. Particle size, carrier, moisture and physical form can therefore be as important as chemical specification.

04/

Formulation Economics:Compare products based on cost per unit of active nutrient, rather than simply price per metric ton. This provides a more meaningful basis when evaluating products with different concentrations.

Built for Feed Production

For feed mills and premix manufacturers, a good additive needs to work smoothly from the warehouse to the mixer.

Easy to Handle:Consistent physical form helps with weighing, conveying and automated dosing.

Easy to Blend:Appropriate particle size and physical characteristics can support more uniform distribution within premixes and compound feed.

Stable During Storage:Moisture control and suitable packaging help maintain product condition during transportation and storage.

Consistent from Batch to Batch:Stable specifications reduce the need for repeated formulation adjustments and incoming-quality troubleshooting.

Suitable for Large-Scale Production:For recurring feed production, supply continuity matters as much as the initial product qualification.

Customized Feed Additive Supply

Different feed manufacturers can have different formulation and production requirements.We can discuss:

Specification Matching

Evaluate products against your existing supplier specification.

Nutrient Content

Confirm available grades and active-content requirements.

Carrier Options

For carrier-based products, discuss suitable carrier types according to the application.

Particle Size

Evaluate available particle-size specifications according to your mixing process.

Packaging

Discuss packaging size and format according to purchasing volume and destination.

Why source feed additives from Longfeng

Scale & continuity

Monthly output of 5,000 t and annual capacity up to 60,000 t, serving 45+ countries — supports stable, repeat bulk supply.

Nutrition & formulation support

Species dosing ranges, product-form selection (HCl vs sulphate, carrier choice), and documentation for your QA and regulator.

Consistency program

Fixed spec windows, retained samples, CoA-matched labeling so your diet performance stays reproducible.

Packaging & Logistics

Feed additives need packaging that protects the product during storage, handling and transportation.

Available Packaging

Depending on the product and order requirements, packaging may include:

PP Bags
Kraft Paper Bags
Inner PE Bags
Carrier-based bags
Customized packaging

For Choline Chloride, carrier type and packaging should be confirmed together because the physical characteristics of the finished product depend on the selected carrier.
