Interestingly, until the development of penicillin and other artificial antibiotics in the 20th century, colostrum was commonly used for fighting bacterial infections. In the early 20th century it was noted that antibody levels in the first milk produced after birth were much higher than levels found in the milk that was produced 72 hours later.There are now over 2000 published scientific articles that document the safety and efficacy of using colostrum. This seemingly perfect food has been shown to be non-species specific.⁵  In 2005, it was reported that is safe and effective in repair of tissues as well as for enhancing immunity.⁶

Bovine colostrum (BC), which can be obtained in large quantities, has been found to be almost identical to human colostrum in terms of its beneficial components. It has also been found to be equally useful for many mammal species, and produces no side-effects. The use of bovine colostrum as dietary supplement has increased substantially over the past decades.Bovine colostrum is harvested within first few hours of calving from dairy animals. The herds of cows are kept under close supervision in good state of hygiene without exposure to antibodies, pesticides and anthelmintic. They are monitored according to FDA criteria. The colostrum collected within 24 hours contains maximum substances but less in amounts, colostrum collected later will be more but contain less immunoglobins
