1. Introduction

Anhydrous magnesium sulfate (MgSO₄) serves as an essential mineral supplement in animal nutrition, providing bioavailable magnesium and sulfur. This document outlines its applications, dosage guidelines, and safety protocols for feed manufacturers.

2. Key Nutritional Functions

2.1 Magnesium Benefits

Bone development & neuromuscular function

Cofactor for 300+ enzymatic reactions

Prevention of hypomagnesemia (grass tetany in ruminants)

2.2 Sulfur Benefits

✓ Methionine/cysteine synthesis

✓ Keratin production (hooves, feathers, wool)

3. Species-Specific Applications

Animal Category Purpose Optimal Inclusion Rate

Dairy Cattle Prevent lactation tetany 0.5-1.5% of DM
