L-Threonine Overview
L-Threonine is an essential amino acid widely used in the feed industry to balance amino acid profiles and improve growth performance.
It supports protein synthesis, enhances nutrient absorption, and contributes to gut health in livestock and poultry.
As animals cannot synthesize threonine on their own, supplementation is essential for modern intensive farming, especially for pigs, poultry, and aquaculture species.
Product Information
This L-Threonine feed-grade material provides consistent amino acid quality for modern animal nutrition.
Active Ingredient: L-Threonine (Feed Grade)
Standard: GB 7300.101-2019
Grade: Feed Additive
Form: White to light brown crystalline powder
Function: Essential amino acid for livestock nutrition
L-Threonine plays a key role in:
– Protein synthesis
– Gut mucin production
– Immune system support
– Nutrient digestion and absorption
It is routinely added to premixes, complete feeds, and concentrate feeds to improve feed efficiency and reduce feed cost.

Product FAQ
1. What is L-Threonine used for in animal feed?
L-Threonine is used to balance essential amino acids in livestock diets, improving growth performance, protein utilization, gut health, and feed efficiency.
2. How does L-Threonine work in livestock nutrition?
L-Threonine supports protein synthesis, gut mucin production, immune function, and nutrient absorption, helping animals achieve optimal performance with lower crude protein levels.
3. Does L-Threonine cause drowsiness or affect animal behavior?
No. Feed-grade L-Threonine does not cause drowsiness or behavioral changes; it functions strictly as an essential amino acid for normal metabolism.
4. Are there any side effects of L-Threonine in animal feed?
L-Threonine is safe when used according to formulation standards. Side effects are not reported in livestock, as excess threonine is metabolized naturally.
5. Is your L-Threonine suitable for all species?
Yes. It is widely used in swine, poultry, aquaculture, and ruminant nutrition to support balanced amino acid levels.
