Crude glycerine is a potential food supply for cattle raised on pasture.

Studies that use glycerine supplementation in grass-feed beef are still incipient.

Glycerine can used as ingredient for supplemented grass-fed ruminants.

Glycerine can affect rumen fermentation and fibre degradation, but did not affect intake and digestibility.

Rumen gran-negative bacteria and protozoa population can be affected bay glycerine.
