Features & Benefits

Product Highlights

This is where CYLACTIN® can help. Containing live Enterococcus faecium, CYLACTIN® is a probiotic feed additive. It stabilizes gut microflora and builds a better intestinal environment by:

  • Limiting the growth of harmful bacteria including E.coli, Salmonella and Clostridia
  • Increasing numbers of lactic-acid-producing bacteria
  • Reducing toxin levels in the intestine
  • Synthesizing protective short-chain fatty acids
  • Stimulating the protection of the intestinal wall

Feeding CYLACTIN® has been shown to reduce incidences of digestive upsets, including diarrhea and MMA (mastitis-metritis-agalactia) syndrome. It thus helps optimize performance, feed conversion and animal welfare.

  • Faster growing, more efficient broilers – improvements in average weight gain and feed conversion.
  • Healthier calves - CYLACTIN® showed to reduce digestive upsets and to increase daily weight gain in pre-weaning calves.
  • Fitter swine - Piglets fed CYLACTIN® are less prone to diarrhea. In finishing pigs, the supplement has shown to improve weight gain and feed conversion, and to reduce mortality.
