NEWS FEED & ADDITIVE MAGAZINE September 2024 113 The animal feed business of Nutreco, Trouw Nutrition is raising awareness of polyphenols as cost-effective antioxidant alternatives that can partially replace vitamin E in livestock diets. The company states that supplementing animal feed with antioxidants is an important practice on the farm given that an oxidative imbalance can harm both animal health and productivity. Severe oxidative imbalances can lead to inflammation, reduced immune function and increased susceptibility to disease. Livestock producers typically include higher levels of vitamin E in the diet to increase animals’ antioxidant capacity and minimise performance losses. However, according to Trouw Nutiriton, a significant rise in the price of vitamin E and the potential for further increases is prompting nutritionists and farmers to seek cost-effective alternative antioxidants to partially replace vitamin E. According to the statement from the company, excessive levels of free radicals result in oxidative imbalance and stress which can damage DNA, proteins, and unsaturated fatty acids, leading to decreased animal performance. Factors that can contribute to free radical formation and an animal’s oxidative status include diet quality, health status, environmental conditions and growth rate, among others. To avoid the potential consequences of oxidative stress, most producers feed vitamin E levels well above the minimum requirements as indicated by the National Research Council (NRC) recommendations and the NASEM guidelines for dairy cattle. In times of high vitamin E prices and, more generally, to optimize protection against oxidative stress, alternative antioxidant solutions should be considered to help safeguard production efficiency.

The shipment builds upon its launch of FeedKind Aqua earlier this year. FeedKind Pet, a non-GMO protein with no animal or plant ingredients used in its production, is now available to pet food manufacturers across Europe, where it can be used in dry kibble, tinned food, or treats. Made by fermentation, the protein was shipped by Calysseo, Calysta’s joint venture with Adisseo to produce FeedKind at commercial scale. Earlier this year, Calysseo received MARA approval from China for use in aquaculture feeds. An export permit granted this spring enabled Calysseo to commence shipping internationally. Calysseo explains it hosts two of the largest fermenters in the world, each with a 10,000-tonne nameplate capacity. Herman Sloot, Vice President of Commercial Development at Calysta says: “For the first time, Europe’s pet food sector has the option to choose a fermented protein that is nutritious and kind to the environment. Starting today, FeedKind Pet will be available globally at commercial scale. FeedKind Pet is already approved for use in both the EU, the UK, Canada, and many other countries.
