The objective of this study was to evaluate the effect of Saccharomyces cerevisiae on nutrient intake and digestibility, the protozoan population and ruminal fermentation kinetics of cattle fed diets containing brewers grains. Four ruminally cannulated crossbreed steers were distributed in a 4 × 4 Latin square. The treatments were in a 2 × 2 factorial arrangement: with or without the inclusion of brewers grains x with or without the addition of S. cerevisiae. Dried brewers grains were included at 11.7% of the dry matter (DM) of the diet. Yeast (S. cerevisiae CNCM I-1077 containing 1.0 × 109 CFU/g) was supplied at 15 g/day. The use of brewers grains and the addition of yeast did not influence the ingestion of DM, crude protein, neutral detergent fiber or total digestible nutrients. Steers fed with brewers grains ingested lower concentrations of non-fibrous carbohydrates (NFC) (P

The objective of this study was to evaluate the effect of selenium-enriched Saccharomyces cerevisiae on the performance, composition and quality of milk from cows fed diets containing dried malt bagasse. Eight Holstein cows were distributed in a 4 × 4 double Latin square. The treatments were in a 2 × 2 factorial scheme: with or without the inclusion of malt bagasse x with or without the addition of selenium-enriched Saccharomyces cerevisiae. Dried malt bagasse was included at 24% in the dry matter (DM) of the diet; the amount of yeast supplied was 15 g/day and was composed of strain Saccharomyces cerevisiae CNCM I-1077 containing 1.0 × 109 CFU/g and 170 mg selenium/kg. Cows fed diets containing malt bagasse presented lower intakes of DM, crude protein and non-fibrous carbohydrates (NFC) and higher intakes of ethereal extract and neutral detergent fiber (P
