The immune system is complex and constantly changing.  In this episode, Alex chats with Hanna on how the immune system is like an elite military force with specialist snipers, foot soldiers and communications and strategy personelle all working off databases of information collected in the field to keep us alive and healthy.  

We apply this knowledge to how we can best bolster the immune response of the production animals that we care for.  Minerals, Selenium, Zinc, Manganese and copper are all critical.  Glucose partitioning in the body can make or break profits.  The exciting field of phytonutrients also holds great opportunity to move away from a dependence on antibiotics to a more natural way of supporting our animals.
