Effect of premixer or premix usage on feedstuff homogeneity

The animal feed industry makes widespread use of micro-ingredient premixers and premixes. Several authors have described the advantages of these techniques. Coelho (1994) considers that the main reason for using premixes is to optimise the dispersion of ingredients. Raghavan (1997) also considers that this rationale is one of the 4 main advantages of using premixes:

• dilution of active products

• facilitation of in-mix dispersion

• lower carry-over risk

• Improved storage stability.
