Rovabio® PhyPlus, a new generation phytase

Rovabio PhyPlus is the last product from Rovabio range launched by Adisseo.

The careful selection of the proper phytase gene allowed to reach a fast, powerful and highly thermostable product.

Thanks to its efficiency, almost all the IP6 can be broken within the first 30 minutes leading to a high release potential of phosphorus from phytates allowing to reach in classicals diet until 87% of phosphorus availability with high dose of 2000 FTU/kg of feed.

Using phytase

Phytases are used in more that 90% of poultry and swine operations. Initially used to fulfil regulatory requirements of Phosphorus excretion limitations, phytases proved over the years to be more than simple phosphorus extractors.

Rovabio PhyPlus mode of action

Rovabio PhyPlus as a 6-phytase starts degrading phytate from Phosphorus in 6th position, then continues until reaching the inositol level.
The enzymatic reaction starts as soon as the feed is being rehydrated with a pH below 6,5 in the crop of poultry. It continues through the digestive system, and gradually loose activity when the pH in the gut get too high for the phytase to work. This is where a full activity at low pH is important to start the phytate degradation soon enough.

What to expect from Rovabio PhyPlus usage?

  • A quick degradation of phytates, limiting their anti-nutritional impacts
  • Release of phosphorus from vegetal raw materials
  • Decrease of mineral phosphorus in formulation need
  • Confidence in getting the dose wanted due to its intrinsic thermostability

Where to find it?

Rovabio Phyplus is currently available in different countries. Following each regional regulatory process, Adisseo will extend the Rovabio Phyplus coverage.
It exists in two different forms: liquid and granulated powder. For other information, please refer to the MSDS.

FAST: 100 % phytate degraded in 30 minutes to counter antinutritional effect

POWERFUL: Ability to extract 80% of phytic phosphorus

THERMOSTABLE: Liquid in the mixer

FEEDASE PROGRAM: Holistic approach on enzyme usage



Rovabio PhyPlus launch happened during a webinar on November 30th 2021. Pierre-André Geraert, Marcio Ceccantini and Baris Yavus introduced the main benefits for our customers to use that new phytase.

Eventually, Claire Xu presented the Feedase Program, the Adisseo approach introduced few years ago to tackle the indigestible part of the feed with enzyme solutions.

  • Pig Feedase approach Article
    At the occasion of Digestive Physiology for pigs congress in Rotterdam, we are sharing an full 12 page article on pig feed digestibility, with a specific focus on anti-nutritional factors and the way to mitigate their effect with enzymes to get the most of the feed.
    Plant by-products are valuable ingredients in the formulation of sustainable and cost-effective aquafeeds, particularly for species with herbivorous and omnivorous habits. However, the use of these ingredients implies nutritional limitations associated to the presence of antinutritional compounds such non-starch polysaccharides (NSPs) and phytate.
