FAQ
What is Nystatin Feed Grade and how does it work?
Nystatin Feed Grade is an
antifungal agent specifically formulated for use in animal feed. It is highly effective in
targeting and eliminating a broad spectrum of fungal organisms, including yeast and molds
that can proliferate in feed materials. The presence of these fungi in feed can compromise
the health and growth performance of livestock, leading to significant economic losses. By
incorporating Nystatin Feed Grade into animal diets, producers can ensure healthier and more
productive livestock.
The mode of action of Nystatin revolves around its ability to
bind to ergosterol, a key component of fungal cell membranes. When Nystatin attaches to
ergosterol, it creates pores or holes in the fungal cell membrane, which leads to the
leakage of essential intracellular contents. This disruption of the cell membrane structure
and function ultimately results in the fungal cell's death. Importantly, Nystatin is not
absorbed systematically and acts locally within the gastrointestinal tract, ensuring that it
specifically targets harmful fungi without adversely affecting beneficial gut flora or the
animal itself.
What types of animals can benefit from Nystatin Feed
Grade?
Nystatin Feed Grade is highly versatile and can be utilized across a wide
variety of animal species, including poultry, swine, cattle, and aquaculture species. Each
