Product Highlights

Higher-performing dairy cows

The cow’s immune system is the first line of defense against udder infections. ROVIMIX® E50 builds a stronger immune system, reducing a cow’s vulnerability to infections.

Feeding ROVIMIX® E50 in the crucial transition period can:

  • Reduce the intramammary infection rate at calving by up to 80%
  • Cut the duration of mastitis cases in infected cows by up to 50%, meaning a faster return to production
  • Lower herd somatic cell counts

The overall effect is higher-producing, more profitable cows.

Better fertility means higher production and fewer early culls. After ROVIMIX® E50 was added to their diets, cows were shown to have fewer days to first oestrus and shorter calving to conception intervals. All of which is good news for farmers aiming to improve fertility.

More robust poultry and swine

A strong immune system is also vital in modern poultry and swine production. By acting as an antioxidant, ROVIMIX® E50 has shown to boost immune function, which supports optimal growth rates and reduces mortality. The result is increased returns from all systems.

Applications & Uses


For animal nutrition in milk replacers and liquid diets, and where stability may be critical, i.e.
aggressive premixes (pH > 10) and canned pet food.
