Compositions and methods for growing the population of microorganisms in a gut of monogastric animals

A composition comprising at least one biologically pure culture of Saccharomyces cerevisiae strain in amount effective for enhancing an average daily gain of monogastric animals and/or growing a population of microorganisms in a gut of monogastric animals and/or a litter thereof, and a suitable carrier.

A feed or food additive comprising the composition comprising at least one biologically pure culture of Saccharomyces cerevisiae strain in amount effective for enhancing an average daily gain of monogastric animals and/or growing a population of microorganisms in a gut of monogastric animals and/or a litter thereof, and a suitable carrier.

A method:

• (A) of maintaining or growing the population of microorganisms in a gut of monogastric animals and/or a litter thereof, the method comprising feeding to the monogastric animals an effective amount of the composition comprising at least one biologically pure culture of Saccharomyces cerevisiae strain in amount effective for enhancing an average daily gain of monogastric animals and/or growing a population of microorganisms in a gut of monogastric animals and/or a litter thereof, and a suitable carrier;
• and/or
• (B) for enhancing an average daily gain of monogastric animals, the method comprising feeding to the monogastric animals an effective amount of the composition comprising at least one biologically pure culture of Saccharomyces cerevisiae strain in amount effective for enhancing an average daily gain of monogastric animals and/or growing a population of microorganisms in a gut of monogastric animals and/or a litter thereof, and a suitable carrier.
