Feed Grade Alpha-Galactosidase
Alpha-Galactosidase (α-Galactosidase) is a feed-grade, solid enzyme preparation designed for the animal feed sector. It is primarily used in livestock and poultry feed to help improve nutrient availability from plant-based raw materials—especially formulas containing soybean meal and other legume-derived ingredients.
Alpha-galactosides are long/short molecular structures formed by linking one sucrose unit with multiple galactose units via α-1,6 glycosidic bonds, mainly including raffinose and stachyose. In animal feed, the main protein raw material is soybean meal, which contains alpha-galactosides and is the most important anti-nutritional factor in corn–soybean meal diets. Studies show that alpha-galactosides in soybeans have relatively good stability and still exist after high-temperature, high-pressure, and high-humidity processing. Alpha-galactosidase can hydrolyze alpha-galactosides in feed, reduce chyme viscosity, improve the digestion of nutrients, and reduce gas and diarrhea caused by alpha-galactosides.
By hydrolyzing these oligosaccharides, Alpha-Galactosidase supports:
- Improved digestibility of plant-based feed ingredients
- Reduced intestinal fermentation linked to indigestible oligosaccharides
- Lower risk of gas and digestive discomfort associated with α-galactosides
- Better nutrient utilization, supporting stronger performance and feed efficiency
Primary application: Used mainly in the animal feed industry (livestock and poultry). Typical use scenarios include formulas for:
- Cattle (including dairy and beef)
- Swine (piglets, growers, finishers, sows)
- Poultry (broilers, layers)
Key translated info included from the product materials:

How It Helps in Feed
In soybean-meal-based diets, raffinose and stachyose can contribute to inefficient nutrient use because animals lack sufficient endogenous enzymes to fully break them down. Alpha-Galactosidase helps degrade these substrates into simpler, more usable components. As a result, animals may experience improved utilization of dietary energy and nutrients, which can contribute to steadier growth and improved feed conversion depending on formulation, management, and species.
This enzyme is typically incorporated during feed mixing or premix preparation. For best results, follow standard feed enzyme handling practices: store sealed in a cool, dry place; avoid prolonged exposure to moisture; and apply according to your feed process and formulation goals.
