Progut® Extra

Progut® Extra is produced via controlled acid hydrolysis of Saccharomyces cerevisiae, releasing high levels of soluble bioactive structures (mannoproteins, β-glucans, oligo-/polysaccharides, nucleotides, peptides). In over 25 rumen simulation studies and multiple field trials, it increased microbial biomass and VFA (↑propionate), delivering more milk with 5–9% better feed efficiency. In calves, Progut® Extra improves fecal and composite health scores and enhances antigen-specific IgA after vaccination, demonstrating immune “training.” Stable through pelleting and storage.

Key Benefits (Ruminants)

• Dairy cows: +2.1 kg milk/cow/day on average across trials (effective at 5–15 g/cow/day)

• Improved feed efficiency: +5–9% (kg milk/kg DMI)

• Calves: better fecal score, improved vaccine response (↑IgA)

• Enhances microbial biomass and rumen VFA (propionate)

• Stable under pelleting and storage conditions

Application Recommendations

• Dairy cows: 5–15 g/cow/day (adjust by lactation stage and target response)

• Beef cattle: 5–7 g/head/day

• Calves: 0.5–1.5 kg/ton of starter feed (or per label program)

• Sheep & goats: 0.5–1.5 g/head/day
