Why is colostrum important: transfer of antibodies across the placenta to fetus does not occur during pregnancy, colostrum provides calf with passive immunity until immune system is developed, main classes of antibodies in colostrum, igg, igm. Identifies and demolishes pathogens found in the bloodstream: recognizes and destroys bacteria solely entering the blood, iga. Fastens to membranes that line organs prevents pathogens from attaching and causing disease: a superior source of energy, protein, vitamins, and minerals, also aid metabolism and development of digestive system. Alternative sources of colostrum for the beef calf: best to have colostrum from herd on hand, from other herds raises biosecurity concerns, colostrum replacements available when it cannot be obtained naturally.
