Quality Technology International's (QTI) Q-Biotic was designed using the company's research and testing lab. The new line of products consist of direct-fed microbial strains alone or in combination. Bacteria strains were selected for their ability to improve animal health, performance and food safety, according to the company. QTI says it also offers combinations of the prebiotic product with the Q-Biotic bacteria strains: BacPack Q1+1 and BacPack Q3+1.
