Even if you can't see it, the mycotoxins in your silage and raw materials may be silently eroding your herd's performance. Vistabuf-T is a triple-action formula that combines the proven rumen buffering of Acid Buf — sustaining pH control for more than eight hours — with the live yeast support of Vistacell and the five-mechanism mycotoxin protection of Nutrisorb, all in a single bag.
Three Problems in Your Ration. One You Can't See.
Rumen acidosis makes itself known: milk yield drops, feed intake falls. Microbial imbalance is felt through inconsistent milk protein. But mycotoxin exposure is silent: it slowly erodes immunity, reduces fertility, burdens the liver, and most often receives a different diagnosis entirely.
Rumen pH Control — Acid Buf
The microscopic honeycomb structure of Lithothamnium calcareum maximises surface contact with rumen fluid while slowing the rate of dissolution in a controlled manner. Different CaCO₃ polymorphic forms — calcite, aragonite, and vaterite — dissolve gradually, sustaining buffering capacity for more than eight hours; standard buffers such as sodium bicarbonate fall well short of this duration. During dissolution, 30% calcium and 5.5% magnesium are released, providing a highly bioavailable mineral source alongside the buffering effect.
Microbial Balance — Vistacell
Vistacell's live Saccharomyces cerevisiae consumes harmful oxygen in the rumen ecosystem, maintaining the anaerobic environment. By competing for sugars, it suppresses the activity of lactic acid-producing bacteria such as Streptococcus bovis and supports the growth of cellulolytic bacteria. The result: more stable rumen pH, improved fibre digestion, and more consistent milk composition.
Mycotoxin Defence — Nutrisorb
Nutrisorb responds not with a single adsorption mechanism, but with five complementary systems working in synergy.
Clay-based binders trap aflatoxins in the gastrointestinal tract through their microscopic crystal structure, preventing passage into the bloodstream. Activated carbon, with its exceptionally high surface area, effectively adsorbs OTA, DON, T₂, ZEA, and FB₁ — providing critical coverage for Fusarium-derived toxins where clay minerals alone are insufficient. Yeast cell wall components selectively bind toxins produced particularly by Fusarium species. Bacterial fermentation products transform the molecular structure of mycotoxins through biotransformation, converting them into non-toxic metabolites that are eliminated via faeces. Silymarin forms a second line of defence against mycotoxin-induced hepatic damage through its antioxidant and anti-inflammatory properties.
Together, these five mechanisms address six mycotoxin families — Aflatoxins, OTA, Fumonisins, ZEA, Trichothecenes, and Penicillium toxins — from a single formulation.
Three Actions. One Application.
A separate mycotoxin protection product means a second dose point and a second cost line. Vistabuf-T delivers rumen management and mycotoxin control from the same bag, at the standard Vistabuf dose — no additional calculation required.
When mycotoxin exposure is reduced in high-silage rations, immune suppression eases, fertility parameters improve, and the root cause of subclinical losses is addressed. Rumen pH control and live yeast support meanwhile maintain the herd's core performance at its baseline.
To protect your herd against rumen acidosis, microbial imbalance, and silage-borne mycotoxin risk all at once, use Vistabuf-T!
Dosage is determined by the nutritionist based on ration assessment and silage mycotoxin risk level. The standard Vistabuf dosage table serves as the baseline; no separate calculation is required for Nutrisorb. Applied via TMR or concentrate feed.
