Perstorp's ProPhorce™ SR celebrates its 10th anniversary


Press release



This quarter, global feed additives producer Perstorp, will celebrate 10 years of commercial application of pioneering its tributyrins solution ProPhorce™ SR in animal nutrition.

ProPhorce SR quickly became one of the company's star products to support gut health and performance. The innovative application of the esterification process ensured odourless butyric acid that is released where it is of most benefit to the animals. To mark the occasion, Perstorp is organising a series of activities to commemorate the product's accomplishments throughout the decade.

A proud pioneer

ProPhorce SR is the pioneering tributyrin solution that revolutionise the market; over the course of a decade, it has become one of the weapons of choice to support gut health and performance, with more than 20 billion broilers treated and used in more than 50 countries worldwide.


"I'm happy that we have been able to help so many customers around the world in improving their performance thanks to the application of ProPhorce SR," says Geert Wielsma, vice president Sales EMEA & Americas and former development team member for ProPhorce SR. "We are about to finalise a new production line in our Dutch feed additives production plant that will facilitate the next decade of growth for our tributyrin solutions."


Looking back and looking forward

This year marks a double celebration for the company as Perstorp is turning 140 years. That's 140 years of thinking about the future and developing smart solutions to advance everyday life in an ever-changing world. One molecule can change everything, and it is under that premise and following focused innovation as its core value, that ProPhorce SR was born.

"When the concept of ProPhorce SR was born and we did our first animal trials, we knew we had something very special in our hands. Feed producers in over 50 countries are using ProPhorce SR nowadays with more than 50 trials ran all over the world. Results can be summarised with two words, efficacy and reliability. We would like to thank our customers for the loyalty and the trust they have placed in the company and in ProPhorce SR during these 10 years; they motivate us to continue providing the market with innovative solutions for the decades to come," says José Maria Ros, global technical manager.
