Abstract
As we know Immunoglobulin or antibodies are kind of protein which is produced by the immune system and fight against microbes or germs. Immunoglobulins are: IgM, IgG and IgA which supply long-term and short-term defense against contamination or infection. Several studies had found that the milk immunoglobulins are able to improve immune defense system response against germs and make available passive immunity, specially, in infants and young animals. The existence of immunologic agents in milk, like lactoferrin and lysozyme, can assist more to its protective effects. And also by incorporation of immunoglobulins and other immune improving materials to the formula milk, we can supply or make ready for the infants the same immunologic benefits like those which got from breastfeeding. We can say that this approach is beneficial for all infants specially it is beneficial for babies that are not able to feed from breast or have compromised Immune Systems.
