Introduction

L-threonine is an essential amino acid that is not only necessary for protein synthesis, but also plays an important role in protecting intestinal barrier function. It is the second limiting amino acid in pig diets and the third limiting amino acid in poultry diets. . With the advancement and development of healthy livestock and poultry breeding technology, L-threonine is increasingly used in the breeding of poultry, shrimp and eels.

The specific technical indicators and implementation standards are as follows:

Functions and Applications

L-threonine powder is often added to the feed of juvenile piglets and poultry.  Adding L-threonine into formula feed has the following characteristics:
1. It can adjust the amino acid balance of feed and promote the growth of livestock;
2. It can improve meat quality;
3. It can improve the nutritional value of feed with low amino acid digestibility;
4. It can reduce the cost of feed raw materials; Therefore, it has been widely used in the feed industry in EU countries (mainly Germany, Belgium, Denmark, etc.) and American countries.

Usage
Directly added to the feed and mixed evenly. Suggested dosage is ≤0.8%.
Storage Condition
Stored in a ventilated, dry, shady and cool place. Do not store it together with items that are poisonous, harmful or with peculiar smell.
Expiration Date
36 months from the date of manufacturing.
Package Specification
25 kg/bag
