Alternative Proteins Magazine NEWS 16 October 2025 Calysta, a company focused on large-scale cultured protein, published a new peer-reviewed research confirming that FeedKind Pet protein is a safe, highly digestible ingredient for adult dogs with promising early signs of supporting gut health. Published in the journal Animals, the eight-month target animal safety study was designed under FDA Center for Veterinary Medicine guidelines and supports Calysta’s planned GRAS notification for the US market. Thirty-two healthy adult beagles were fed diets containing up to 8% FeedKind Pet protein for six months, followed by a twomonth period on a control diet. The results reportedly reaffirm that FeedKind Pet protein can be safely included in dog food, maintaining healthy weight and body condition scores throughout, with no impact on feed intake and high digestibility. Protein and energy digestibility exceeded 80%, and fat digestibility exceeded 90%. The study also revealed positive shifts in the dogs’ fecal microbiome, increasing alpha diversity, an early sign of potential gut health benefits. Key findings from the study have been highlighted as: • Long-term safety confirmed: All dogs maintained normal health, weight, and body condition. • High digestibility: Protein and energy digestibility consistently above 80%, fat above 90%. • No feed intake impact: Dogs readily accepted FeedKind Pet at all inclusion levels. • Positive microbiome effect: Inclusion increased alpha diversity and promoted healthy bacteria, signs of gut health support.

Under the joint venture, Beta Bugs will become MYGroup’s exclusive supplier of BSF eggs, with a new breeding and hatching facility to be established at the waste management company’s the Maltings site at South Milford, near Leeds, England. The new in-house breeding and hatching facility will complete MYGroup’s Insectology process endto-end, ensuring a reliable and consistent supply of eggs and neonates. MYGroup will draw on Beta Bugs’ specialist expertise in establishing and up-scaling BSF hatchery operations and their superior genetics to optimise the Insectology process. Beta Bugs will leverage an oversized breeding site to enhance their supply of high-quality breeding stock to the UK market. Steve Carrie, Group Director, MYGroup, said, “With the vertical integration of egg supply directly into our Insectology process, together with enhanced breeding and hatching capabilities, we’re able to ensure optimal quality, reliability and transparency at every stage. Beta Bugs are the perfect partner – innovative, highly specialised and equally committed to scaling BSF bioconversion as a mainstream solution for food waste and the sustainable protein market.” Read more>> UK insect farming venture targets food waste reduction Photo: Courtesy of Beta Bugs Photo: Freepik
