Functional Benefits in Feed

As an exogenous protease, this ingredient complements endogenous enzymes to accelerate plant protein digestion and animal protein digestion. It is particularly effective as a soybean meal digestion enzyme and corn gluten digestion enzyme, unlocking bound amino acids and improving nitrogen utilization. Its targeted action helps reduce anti-nutritional factors that otherwise limit nutrient absorption, making it a strategic animal nutrition additive and growth performance feed additive in cost-optimized feed programs.

When included as protease for feed premix or in complete feeds, the product delivers consistent performance across raw material variations, supporting lower formulation costs and improving feed conversion ratios. These advantages make it an essential livestock nutrition enzyme for commercial operations seeking measurable improvements in productivity.

Applications by Species

Poultry Diet Optimization

Use as a poultry feed enzyme and protease for poultry to enhance amino acid availability in broiler, layer, and breeder diets. It helps mitigate variability in plant meals, stabilizes performance, and supports growth and egg production with consistent amino acid release.

Swine Nutrition Programs

In piglet, grower-finisher, and sow feed, this swine feed enzyme and protease for swine improves nutrient digestibility, alleviates protein fermentation in the hindgut, and contributes to better gut health and performance outcomes.

Aquaculture Formula Enhancement

Applied as an aquaculture feed enzyme and protease for aquaculture, it supports the breakdown of both marine and plant proteins in fish and shrimp diets, improving feed utilization and minimizing nutrient waste in aquatic environments.

Quality Assurance and Safety Parameters

The product is manufactured to strict specifications as a low heavy metals protease. Each batch adheres to the following testing standards to ensure safe and reliable use in animal nutrition:

These parameters ensure the enzyme remains active across typical feed processing and digestive conditions, maintaining efficacy from mill to gut.

Handling, Storage, and Packaging Options

Our animal feed protease is available as bulk protease powder or protease granules to suit different manufacturing needs. Standard supply is in 25kg protease bags with moisture-resistant liners. For specialized requirements, we offer customized packaging protease solutions, including small sachets or big bags to support diverse production scales. Store in a cool and dry location, protect from humidity, and rotate stock on a first-in, first-out basis to maintain labeled activity over the 12–24 month shelf life.

Usage Guidance and Compatibility

Incorporate this feed enzyme protease directly into complete feeds or use it as protease for feed premix for precise dosing. It can be combined with other enzymes and nutrients to maximize performance. Consider pairing with complementary solutions such as:

• Phytase for phytate breakdown
• Amylase for starch hydrolysis
• Beta-mannanase for NSP reduction
• Xylanase fiber-degrading enzyme
• Glucose oxidase stability aid
• L-Lysine HCl amino acid source
• DL-Methionine supplement
• Tributyrin gut health additive

Such combinations further enhance nutrient availability and support holistic feed programs targeted at performance and health.
