Improved stability with Vistacell Vistacell is a live yeast product of the Saccharomyces cerevisiae variety Dried in granular form, Vistacell has an outer shell that serves to protect an inner core of live yeast cells This process serves to improve stability, making Vistacell one of the most active live yeast products commercially available, with an activity of 2 x 10e10 cfu/g Vistacell in ruminant nutrition Adding Vistacell to the ration can help increase rumen pH This reduces the number of lactic-acid producing microbes, whilst increasing the number and activity of fibre-digesting microbes Improved fibre digestion and dry matter intake result in greater productivity
