Product storage stability Three batches of the product was stored at 25°C/60% RH or 40°C/75% RH for 24 or 6 months, respectively. At the low temperature the residual activity of the bacteria was unaffected whereas 10% of the protease activity was lost. When stored at the highest temperature, 30% of the protease activity was lost after four months but bacterial counts remained unaffected.
Storage stability in feed and premix Bacterial count and protease activity were measured in a premix stored for a period of six months at 25°C/60% RH. After six months no loss of bacteria could be detected whereas the protease active dropped by 23%. A similar set-up with the same temperature and RH was used to test the stability of the product when added to a mash feed. The residual bacterial and protease activity was hardly affected by six months of storage.
Heat stability Pelleting at 65°C reduced the protease activity by approximately 50% and a reduction in the bacterial count by 35%
Handling The product should be considered as a skin sensitiser and has also the potential of being a respiratory sensitiser
