Preferably Use Colostrum from the Calf’s Own Mother

“Since a calf is born without any resistance, it is completely dependent on the antibodies from the colostrum, known as passive immunity. Fortunately, the calf develops its own active immunity. Building an active immune system can only be successful if the animal remains healthy during this development phase. Illness not only hampers growth but also delays the development of the calf’s own immune system. Additionally, a pathogen or bacteria can be much more detrimental to the calf during this phase than when its immune system is fully developed. Therefore, a good colostrum supply on day one has a significant impact on preventing lung problems in the second month.”
