Probiotic Ultra for Ruminants

+4.6% higher Average Daily Gain
+12.8% greater Feed Conversion Efficiency
+$57 more per head Return on Investment

Our Probiotic Ultra packs 130 billion bacteria in every gram. The three Lactobacillus strains found in Probiotic Ultra optimise feed digestion, increasing nutrient availability to the animal, whilst amplifying other beneficial bacteria.

"The novel Terragen dried bioactive supplement, Probiotic Ultra for Ruminants, at the higher concentration, produced a lift in both production and carcass performance in steers fed on a traditional 110-day grain-fed program. These results show significant promise for the Terragen Probiotic Ultra for Ruminants supplement to increase feedlot cattle performance on short or mid feeding programs."
