Application of Sodium Sulphate Anhydrous feed grade
August 11, 2026
Sodium Sulphate Anhydrous (Feed Grade) refers to the anhydrous form of sodium sulfate (Na₂SO₄) that meets the quality and safety standards for use in animal feed. Below is a clear, professional overview of its applications in the feed industry.
Main Applications in Animal Feed:
Sulfur Source for Amino Acid Synthesis
Provides inorganic sulfur, which is utilized by rumen microbes (in cattle, sheep, goats) to synthesize sulfur-containing amino acids such as methionine and cysteine.
Supports protein synthesis and milk production in dairy cows, and wool growth in sheep.
Electrolyte and Osmotic Balance
Supplies sodium (Na⁺) and sulfate (SO₄²⁻) ions.
Helps maintain:
Osmotic pressure
Acid–base balance
Proper hydration status
Especially useful in diets for:
Young animals (piglets, calves) under stress
Poultry during heat stress to support electrolyte balance
Laxative Effect (Mild)
At higher dietary levels, sodium sulfate has a mild laxative effect in monogastric animals (pigs, poultry).
Helps prevent constipation and supports gut motility, particularly:
After weaning in piglets
During dietary transitions
Detoxification Support in Ruminants
Sulfate can be reduced by rumen microbes to sulfide, which binds certain toxic elements (e.g., excess molybdenum, dietary copper imbalances).
Used in areas with high molybdenum in forages (“teart” pastures) to prevent molybdenosis and secondary copper deficiency.
Carrier or Diluent in Premixes
Due to its free-flowing, non-hygroscopic nature (anhydrous form), it is sometimes used as:
A carrier for trace minerals
A flow agent in vitamin–mineral premixes
