Product storage stability Three batches of the product were stored in sealed bags for 24 months at either 22°C or 37°C. After 24 months of storage, the loss of Bacilli was less than 0.5 log values.
Storage stability in feed and premix A vitamin/mineral premix was supplemented with three different batches of the product. Samples of the premix were stored for six months at either 22°C or 37°C in sealed foil bags. The loss of bacterial count was less than 0.5 log values after six months. 
Storage of pelleted feed supplemented with the product for three months did not affect the number of viable counts. Similar studies with mash feed confirmed no losses of viable counts after three months of storage.
Heat stability Mash feed supplemented with the product was pelleted for 30 s at 95°C. No loss of viable counts was detected. 
Homogeneity The sub-samples of a mash poultry feed were used to study the capacity of the product to distribute homogeneously in the feed. The coefficient of variance found in the sub-samples was 3%.
Particle size The fraction of particles below 100 μm was c. 2 %.  The mean value of the dusting potential is 0.48 g/m3. 
Compatibility claims The product is compatible with: narasin/nicarbazin, maduramicin ammonium, lasalocid A sodium, salinomycin sodium, monensin sodium, robenidine hydrocholride, diclazuril, decoquinate, semduramycin sodium or nicarbazin.
