Stafac ® (virginiamycin)


Stafac is an anti-infective for use in poultry feeds to control enteric diseases.  By maintaining a healthy balance of bacteria in the intestinal environment, Stafac improves feed efficiency and rate of weight gain in chickens and turkeys.

Stafac selectively controls the intestinal microflora in the upper small intestine, preventing the bacterial breakdown and use of essential amino acids, as well as energy-containing monosaccharides such as glucose. This can result in a significant nutrient-sparing effect, as well as an energy-sparing effect. Ultimately, fewer units of critical nutrients per unit of feed are required, leading to significant savings in feed formulation costs.

Stafac has no withdrawal requirement.
