1 st WorkshopXIII International Feed Technology SymposiumCONCLUSIONComparision of different tracers led to conclusion that choosing of appropriate tracer isvery important and that tracer must have distribution of particle size that is similar to thedistribution of particle size of mixture. FS and F tracers gave opposite trend of valuechanging, compared with RF tracer, which caused incorrect conclusions abouthomogeneity of mixture. This is result of difference between particle size distribution ofFS and F tracers and carrier which, leads to decomposition during mixing process.ACKNOWLEDGEMENTSResearch work in this paper is result of the project no. 20106: “Development ofTechnologies for Sustainable Feed Production” which is founded by the Ministry ofScience and Technological Development of Serbia.LITERATURE1.
