Colostrum
Colostrum is the antibody-rich fluid produced from the mother during the first day or two after birth. It contains a number of antibodies and growth factors. Most commercial colostrum preparations come from cows. Ideally, colostrum should come from a dairy that does not use hormones, pesticides, or medications in the cows that might concentrate in the colostrum.
Whether cow antibodies are good for humans or pets is unclear, although many holistic veterinarians anecdotally report positive results with both colostrum and the more concentrated form called lactoferrin. Lactoferrin is a component of colostrum. By concentrating the intended nutrient, instead of having a tiny amount of it, as found in colostrum, the effect may be maximized in the body. Transfer Factor is a patented antibody rich fragment of colostrums.
