The Effect on Mycotoxin Development of Combined Organic Acid Additive at Different Levels in Dairy Feed

Organic acid treatment to prevent deterioration of feeds by exposure to mycotoxins and to extend their storage life is the most important requisite of natural, safe and wholesome feed production. (1) Background: The aim of this study was to determine the effects of an organic acid (OA) combination added in incremental levels to commercial dairy feed, on mycotoxin development in feeds stored for varying lengths of time; (2) Methods: For the trial, a total of 5 treatment groups were formed as control, 10 lt water only (without OA), and 10 lt water with respectively 0.2, 0.3 and 0.4 kg/ton OA addition. The trial conducted in a commercial feed mill for a span of 3 months from March through May, was set-up in a 3x5 factorial plan, taking into account the effect of groups and storage duration in months. Deoxynivalenol, zearalenone, aflatoxin, fumonisin B1, T-2 toxin, ochratoxin, fumonisin B2 and HT-2 levels were measured in the feed samples taken at certain control points of the feed manufacturing process, that is to say after the mixer, conditioner and cooler, and stored for three months; (3) Results: It was determined on the basis of the results that, deoxynivalenol and aflatoxin levels significantly decreased (P
