BIOGROW
The Natural Feed Additive
Calves
Biogrow for Calves
Biogrow is a microbial feed additive developed for use in calf milk replacers and
also for inclusion in coarse and pelleted feed.
The active ingredients in Biogrow are the bacterial strains Bacillus subtilis and
Bacillus licheniformis which produce digestive enzymes as they progress along the
intestinal tract. These enzymes assist in the breakdown of feed, resulting in
efficient feed conversion rates and improved live weight gains. This is shown in the
following trial data.
