Mankind produces more than 1.1 billion tonnes of animal feed annually for the nutrition of livestock and pets. The feed industry is dependent on >75% of soy and >65% of the total fish harvested globally as protein to cater to this demand. With increasing population and growing demand for protein-rich food, sustainable and scalable solutions are needed to meet global needs.
String has enabled advanced biomanufacturing of high-quality fermented ingredients for the animal nutrition sector that directly address these gaps. These ingredients are manufactured using a sustainable manufacturing process that enables clean, traceable, safe and consistent output. Our products deliver significant benefits to the animal, feed manufacturer, farmer, and the end customer, ensuring all parts of the supply chain stand to gain by its use.
Our first product to market, PRODG® with >70% crude protein, is a high-quality protein ingredient that addresses the $70 billion protein feed ingredient market. Validation studies in specific aquatic and poultry species demonstrated excellent performance even at high levels of inclusion in feed. Use of PRODG has been validated in different aquatic animals such as the pacific white shrimp, Litopenaeus vannamei , rainbow trout, Oncorhynchus mykiss , yellowtail kingfish, Seriola lalandi and Barramundi, Lates calcarifer. Sustainable feeds formulated with PRO-DG result in healthy body weight gain of animals, good digestibility and optimal feed conversion ratio (FCR). In certain species, use of PRODG has demonstrated beneficial effects on the gut health of animals. A pilot study in canine diets demonstrated PRODG to be palatable with positive effect on the gut microbiome.
Our solutions also tackle the challenges of limited fishmeal availability and volatile pricing, fostering greater industry resilience. Its production protects aquatic ecosystems by reducing reliance on wild-caught fish, safeguarding biodiversity and promoting responsible resource management.
String’s protein ingredients have been validated in multiple geographies, varied farm management practices and by leading global feed manufacturers. Our vision is to enable the transition of the feed industry to sustainable, clean and, traceable value chains by leveraging the power of biology.
