Each capsule delivers a concentrated dose of live Saccharomyces cerevisiae yeast cells along with niacin (vitamin B-3) to help support normal rumen fermentation and digestive balance. The formula is intended for beef and dairy cattle experiencing reduced feed intake, such as following calving, freshening, arrival in a feedlot, or after a course of antibiotics. Capsules are packaged in a jar and are given orally, with no mixing into feed required. The product supplies direct-fed microbials intended to help repopulate beneficial rumen bacteria and encourage dry matter intake. Dosing is typically once daily for a short succession of days rather than a single treatment. It is offered in multiple pack sizes so operations can match supply to herd size and frequency of use.
