How can you help the bacteria in the cows stomach?

Give the cow something that she would eat, like grass or hay. If you are wanting to switch diets, GO SLOW. Don't switch her to a totally different diet in one day, drag it out, by increments, over several weeks so the bacteria in her stomach have time to adjust.

It's also very important to feed a cow for optimum rumination and digestion, not maximum digestion like you would with monogastrics like hogs and poultry.
