Impact contains dried bovine colostrum with added lactoferrin and lactoperoxidase. Feed to newborn mammals as a colostrum replacer or to marsupial joeys as a milk supplement. Colostrum is the first milk produced after birth and contains high levels of immunoglobulins. These are proteins that protect against harmful micro-organisms such as bacteria and viruses. Newborns that don't receive adequate colostrum have a weakened immune system and increased risk of disease and mortality. Colostrum also contains antibacterial proteins such as lactoferrin and lactoperoxidase which help protect the gut by inhibiting the growth of intestinal pathogens. Comes in 100g tub.
