What is L-Threonine?

L-Threonine is an essential amino acid that cannot be synthesized by animals and humans. It is the third limiting amino acid for livestock breeding, only after Lysine and Methionine.

With the global popularization of low-protein precision breeding solutions, L-Threonine has become an indispensable raw material for feed formula optimization, widely purchased by overseas feed mills, premix enterprises and aquaculture groups.
Insufficient threonine in daily rations will lead to reduced feed intake, slow growth, poor feed conversion rate and weakened immunity of animals.

Core Functions of Feed Grade L-Threonine

1. Optimize Feed Formula & Cut Raw Material Costs

Precisely balance the amino acid ratio of daily feed to match the ideal protein demand of animals. It can lower the crude protein proportion in formulas and reduce consumption of high-cost protein raw materials such as soybean meal. It is a mainstream cost-saving solution adopted by feed enterprises worldwide.

2. Boost Growth Performance & Improve Feed Conversion

Promote protein synthesis in livestock, poultry and aquatic animals, increase daily weight gain and lean meat rate, reduce feed conversion ratio, shorten breeding cycles and raise overall breeding profits.

3. Strengthen Anti-stress Capacity & Lower Mortality Rate

Participate in antibody production, repair digestive tract mucosa and reinforce the immune system of animals. It relieves environmental stress caused by high temperature, group transfer and reduces disease losses in large-scale breeding.

4. Reduce Ammonia Emission to Meet Global Environmental Standards

Improve nitrogen absorption and utilization of animals, cut nitrogen content in manure and urine, lower ammonia concentration in farms, and comply with green breeding regulations in Southeast Asia, Europe and America.

5. Excellent Compatibility Suitable for All Kinds of Feed

The powder features good fluidity, anti-caking property and high thermal stability. It can be directly added to complete feed, concentrated feed, premix and aquatic compound feed.
