Partner with us to enhance animal welfare and drive production efficiency.

Key Features & Benefits

• Stress Reduction & Improved Behavior: As a direct precursor to serotonin, L-Tryptophan helps calm animals during stressful periods like weaning, transport, and regrouping. This significantly reduces harmful behaviors such as tail-biting in pigs.
• Enhanced Feed Intake: By modulating appetite and mood, L-Tryptophan encourages consistent feed consumption, especially during periods of stress or environmental challenge, leading to better growth rates.
• Enables Low-Protein Diets: Allows nutritionists to lower the crude protein content in feed while meeting the animal’s exact amino acid requirements. This reduces feed costs and lowers nitrogen excretion, benefiting both your budget and the environment.
• Guaranteed Purity & Bioavailability: With a minimum purity of 98.5%, our product ensures precise formulation and maximum bioavailability, delivering reliable and consistent results in every batch of feed.

Primary Applications for L-Tryptophan 98.5%

L-Tryptophan 98.5% is the fifth limiting amino acid in swine and plays a vital role in poultry diets, making it a strategic tool for animal nutritionists.

For Swine:

• Weaning Piglets: Added to starter diets to ease the transition, improve feed intake, and reduce stress-related behaviors.
• Grower-Finisher Pigs: Used to balance low-protein diets and minimize aggression in group housing systems.
• Sows: Helps improve feed intake during lactation, which is critical for milk production and subsequent reproductive performance.

Poultry:

• Broilers & Turkeys: Included to manage stress from high stocking densities and heat, improving overall flock performance and welfare.
• Layers: Can help reduce feather-pecking and other stress-induced behaviors.
