Hamlet Protein appoints global swine manager

Feed industry and livestock producers alike recognize the importance of young animal feed, as it determines the performance throughout the animal’s lifetime. Supplementation of high-quality specialty ingredients and precision feeding during starter diets can increase intestinal activity and development, improve digestion and absorption of nutrients, increase muscle development, and promote earlier development of immunity.

Jessika van Leeuwen, Dutch citizen, graduated from Wageningen University (NL). After a minor from the University of Florida (US) and a post-graduate from University de la Plata (ARG), she completed a PhD on Reproductive Physiology at Wageningen University. Jessika has held senior position at industry leading companies in animal feed and feed additives. “Hamlet Protein is recognized in the market for its flagship product HP300, that is known to consistently deliver value in piglet nutrition. I am looking forward to become part of the global team and continue to build on Hamlet Protein’s network and experience,” commented Mrs. Van Leeuwen.

Even though Hamlet Protein offers products across all species, it has become well known for the application of HP300 in piglet nutrition. Low in anti-nutritional factors, HP300 increases feed intake, results in improved weight gain and feed conversion ratios when compared to other protein sources.

Erik Visser, Hamlet Protein CEO, stated: “We strive to be a true customer centric company. In our case that means being able to deliver best in class support to our customers across the world. That is why we are investing in global species managers. I am confident that Jessika, with her academic and professional credentials, will contribute to further strengthening our position as market leader in soy specialty protein ingredients for piglets.”


Providing the right nutrition in the first life stage determines the overall lifetime performance of the animal. Our soy-based specialty ingredients improve health, welfare and performance of young animals. That is how we deliver a strong return on investment to producers around the world.
