Why Rumenox®
How Rumenox® works
There are many benefits to Rumenox® and it’s due to the way it works. Rumenox® helps a cow’s rumen function better, adjusting fermentation to a level that’s more beneficial to the overall health of the cow. Cows are more likely to stay in optimal condition which not only supports in-calf rates but also protects against ketosis and bloat.
Rumenox® helps cows get in calf
When cows are on Rumenox® there is a beneficial fermentation shift and better rumen function, year round.
This has a big impact on reducing the risk of ketosis, a disease that stops cows from getting enough energy from their feed. Instead, they take it from their body fat which not only increases the risk of endometritis but affects in-calf rates.
Rumenox® helps cows avoid ketosis so they’re better able to get in calf. Studies show that Rumenox® reduces the risk of ketosis by 40%.
Rumenox®, the better bloat protection
For peace of mind bloat protection, you can’t go past Rumenox®.
