Zearalenone, Deoxynivalenol, Fumonisin, Ochratoxin and T-2/ HT2. When the mycotoxins are measured, the NutriOpt Mycotoxin Adviser provides real-time and customised advice on how to respond to mycotoxin levels in raw materials and in complete feeds. “These analysis tools support informed decisions on accepting or rejecting raw materials and are part of an integrated mycotoxin risk management, including the TOXO product range and inclusion rates”, Haladi explains.
Mitigating pathogen risk It is also very important to prevent contamination of feed ingredients or finished feed with pathogens. Salmonella for example can be easily introduced into the feed by contaminated ingredients, sub-optimal processing, and sub- hygienic transport, storage, distribution, and administration. It is thus of utmost importance that products are tested for presence, type, and number of bacteria. Mitigating pathogen risk should be done as early as harvest time, during transportation or later in the value chain, upon receipt and storage. Applying specific potent blends of buffered and non- buffered organic acids can help prevent harmful microorganisms (such as Salmonella and E. coli) from metabolising valuable nutrients. “Managing microbes is also key when feeding silage, liquid feed or by-products from the food and beverage industry. Liquid feeding practices are common at some pig farms and by-products are increasingly used in all kinds of animal diets because of their nutritional value, price, and increased availability. Using synergistic blends of organic acids and surfactants helps to reduce yeasts,
moulds and Enterobacteria, while preserving nutritional value”, explains Evelien van Donselaar, Global Programme Manager Feed Safety at Trouw Nutrition. Salmonella can be introduced and spread not only through feed but also through drinking water. Acidification with organic acids reduces the pH of the drinking water and supports water hygiene in the presence or absence of chlorine.
Integrated feed safety approach Ensuring high-quality feed materials and maintaining the nutritional value of feedstuffs requires more than a single solution. Applying a product to the silage or finished feed may positively impact feed quality in the short term but does not offer a long-term solution to maintain quality throughout the entire feed-to-food chain. Trouw Nutrition focuses on an integrated approach and uses its MasterLab expertise and services, dedicated programmes on feed safety and mycotoxin risk management to ensure safe and high-quality feed along the whole production chain. Implementing an integrated approach ensures early warnings are detected and corrective measures can be introduced in a timely manner. Furthermore, it allows for evaluation of the actions taken to prevent re-occurrence of the negative impacts. Offering this total package of services and using a comprehensive and effective combination of detection methods, customised advice and recommendations, products to prohibit micro- organisms’ growth, as well as applying high-quality mycotoxin binders, has proven to be a valuable solution for many feed producers and farms around the globe.

Crops in the field, feed pro- cessing at the mill, biosecurity measures during feed transport, and safe storage on the farm all contribute to feed safety.
