Course supplement to restore rumen microbiota, improve fermentation, and strengthen immunity after transition, deworming, or antibiotic treatment.

Ovi Transition

Quick summary

  • Transition course to stabilize microbiota, fermentation, and immune resilience.
  • Relevant during feed transitions and after deworming/antibiotic periods.
  • Combines microbial support, fermentable substrates, and trace elements.
  • Field protocol: lambs for 21 days, ewes for 7 days.

Frequently asked questions

When should Ovi Transition be used?

During feed transitions and after deworming or antibiotic treatments.

What is the recommended protocol?

Post-weaning lambs: 15 g/day for 21 days. Ewes: 20 g/day for 7 days.

What benefits are expected?

Support for rumen microbiota, fermentation efficiency, and immune resilience.

Are there incompatibilities?

Yes. Avoid combining with other fermentable sugar sources and oral macrolides.

Main objectives

  • Restore rumen microbiota.
  • Improve rumen fermentations.
  • Strengthen animal immunity.

Key components

  • Lactobacillus rhamnosus/farciminis: beneficial flora support.
  • Lactose + dextrose: fermentable substrates.
  • Inactive Saccharomyces cerevisiae yeasts: fermentation support.
  • Cobalt, selenium, zinc, iodine: metabolic and immune support.
  • Vitamins A, B1, B12, E + chamomile flowers: broad support in stress periods.

Usage periods

  • Feed transition.
  • Post-deworming and post-antibiotic treatment.
  • Course to boost immunity.

Usage conditions

  • Post-weaning lambs: 15 g/day for 21 days.
  • Ewes: 20 g/day for 7 days.

Precautions for use

  • Mix with feed before distribution.
  • Always provide clean water.
  • Do not combine with other fermentable sugar sources or oral macrolides.
