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
Storage stability in feed and premix
Three different batches of the product were supplemented to a vitamin/mineral premix. 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 seconds 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%.
Physical properties
The fraction of particles below 100 μm was about 2 %. The mean 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 hydrochloride, diclazuril, decoquinate, semduramycin sodium or nicarbazin.
Handling
Inhalation of dust should be avoided. Gloves and goggles should be worn to reduce contact with dust.
