Products Description
Threonine exists as a white crystalline powder, odorless, with a slightly sweet taste, and it is highly soluble in water. Feed - grade threonine has a purity of not less than 98.5%, featuring excellent stability, which makes it less prone to loss due to high temperatures during feed processing.

Applacation
Balancing Amino Acids and Enhancing Protein Utilization
Threonine is an essential amino acid for pigs, poultry, and other animals, often serving as the second or third limiting amino acid (after lysine and methionine) in corn-soybean meal-based diets. Supplementation optimizes amino acid ratios in feed, especially in conjunction with lysine and methionine, reducing protein decomposition and promoting efficient protein utilization. For example, adding threonine to low-protein pig feed maintains amino acid balance and avoids growth inhibition caused by protein deficiency.
Intestinal Development and Immune Enhancement
As a precursor for intestinal mucosal cells and immunoglobulins (e.g., IgA), threonine strengthens intestinal barriers to reduce pathogen invasion. In young animals like weaned piglets, threonine supplementation alleviates intestinal inflammation, improves villus structure, and lowers diarrhea rates. It also participates in antibody synthesis, enhancing immunity under stress (e.g., transportation, disease).
Regulating Fat Metabolism and Meat Quality
Threonine inhibits liver fat synthesis and promotes fatty acid oxidation, reducing body fat deposition. In pig farming, it increases carcass lean meat rate; in broilers, it decreases abdominal fat accumulation to improve slaughter quality.
Application in Special Physiological Stages
Lactating Sows: Threonine supplementation during lactation increases milk secretion and milk protein content, improving piglet survival rate and weaning weight.
High-Yield Laying Hens: Adding threonine during peak laying maintains eggshell membrane protein synthesis, reducing broken egg rates and enhancing egg weight.
