Dual-tracer analysis of animal feed carry-over patterns during plant manufacture

Summary

This test was designed to study changes in carry-over patterns at four sampling stations at a given industrial site, both before and after pelleting, using two tracers: Chlortetracycline (CTC) and the micro-tracer RF-Blue Lake (MT). This site was the same one used to study trends in compliance and homo-geneity (i’Tec_H12).
