Product storage stability
No loss of viability was observed after 12 months of storage at 20°C or storage for six months at 37°C
Storage stability in feed premix
No loss of viability was observed after six months of storage of premixes supplemented with the additive. The premixes were stored at 20°C. Likewise, complete mash and complete pelleted feed were supplemented with the additive and stored for three months at 20°C. No loss of viability was observed in the complete feed.
Heat stability
Heat stability was tested at three different temperatures: 60, 70 and 80°C. After pelleting, the feed was analysed, and the subsequent viability was close to 90% or higher
Homogeneity
The distribution of the additive, when added to a final feed, was tested. Analyses of ten sub-samples showed a coefficient of variation of 11%
Compatibility claims
Compatible with diclazuril, nicarbazin, decoquinate, Lasalocid A sodium, monensin sodium, robenidine hydrochloride, maduramicin ammonium and halofuginone hydrobromide
Carrier
Calcium carbonate, maltodextrin and silicium dioxide
Handling
Inhalation of dust should be avoided. Gloves and goggles should be worn to reduce contact with dust.
