NEWS 98 FEED & ADDITIVE MAGAZINE June 2025 The results of a study by the Federal University of Paraiba in Brazil show that the inclusion of ProteinX, Protix’s black soldier fly protein, can improve the skin barrier of dogs and strengthen their antioxidant defences. The findings, published in Archives of Animal Nutrition, are particularly good news for dogs that suffer from skin diseases or allergies, Protix points out. Versatile ProteinX can be incorporated into a variety of end products, from wet food to kibble and (nutritional) treats, so the study opens up various opportunities for manufacturers to develop healthy pet products. The skin barrier acts as an important defence mechanism in dogs. An effective skin barrier is essential for maintaining hydration. It protects against allergens, viruses, bacteria and environmental toxins, and ultimately helps to keep the overall skin healthy. According to the announcement, there was a noted improvement in skin barrier function when the canines consumed the ProteinX-based diet. Transepidermal water loss decreased at both the pinna and belly, indicating improved water retention. There was also a significant increase in stratum corneum hydration at the belly (the outermost layer of the skin serving as the primary barrier between the body and the environment), suggesting enhanced skin hydration. Protix explains that ProteinX contains relatively high concentrations of lauric acid and linoleic acid which may account for the improvements in skin barrier function and water retention.

The certification was formally awarded during a ceremony at Seafood Expo Global in Barcelona, Spain, held on 6-8 May, 2025. The new ASC Feed Standard provides a comprehensive framework for responsible aquafeed production, setting stringent requirements across key areas including social and labour rights, health and safety, environmental stewardship, and responsible sourcing of raw materials. "Skretting’s commitment to sustainability across its entire value chain is evident, and I congratulate them on achieving ASC Feed certification. The new ASC Feed Standard ensures that aquafeed production is carried out responsibly, addressing both environmental and social impacts across the entire supply chain. It promotes transparency, traceability, and continuous improvement in the aquaculture industry, ultimately contributing to more sustainable and ethical seafood production," said Stefano Crea, Global Market and Industries Director at DNV. "At Skretting, our commitment to delivering sustainable feed begins with responsible sourcing. The ASC Feed Standard provides a robust methodology to better identify and mitigate legal, environmental, and social risks associated with the raw materials we use. Importantly, the standard addresses both environmental and social impacts and offers a strong framework for upholding human rights," expressed Sergio Alanis, Managing Director Business Unit Southern Europe at Skretting.
