products. These regulations also dictate the types of feeds (e.g., poultry, swine, cattle)
where Sodium Metabisulfite can be applied, ensuring that the specific needs and tolerances
of different animal species are addressed.
Understanding the interaction of Sodium
Metabisulfite with other feed additives is also crucial. Some substances may either enhance
or inhibit its effectiveness. For example, the presence of certain minerals or organic
materials may affect its stability and, consequently, its preservative properties.
Therefore, consulting compatibility charts and conducting preliminary tests can be
beneficial before large-scale application.
