The effect of live yeast Saccharomyces cerevisiae as probiotic supply on growth performance, feed intake, ruminal pH and fermentation in fattening calves.

Background: Live yeast Saccharomyces cerevisiae has been used for a long time in ruminant feed as a probiotic supply on the intensifying system to avoid acidosis.

Objectives: This study investigated the effects of addition of live yeast S. cerevisiae in calf feed on growth, rumen pH and in vitro digestibility.

Effect of yeast culture feed supply on growth, ruminal pH, and digestibility of fattening calves.

This study was carried out to predict the effects of yeast culture on growth, intake, and digestibility in vitro of calves for fattening. The trial involved 16 fattening calves divided into two homogeneous groups ( = 8), based on the initial body weight (414 ± 25.1 kg and 416 ± 24.
