Humoral immunity factors (IgG) and their role in calf immunity: a review
https://doi.org/10.25687/3034-493X.2025.3.2.002
Abstract
Passive immunity obtained with colostrum is of critical importance for the health and well-being of newborn calves. There are a large number of factors that can influence the absorption of immunoglobulins (IgG) by calves, which are important to consider from the preparation of pregnant animals for calving to the technology of preparation, collection and feeding of colostrum itself. Direct and indirect methods allow us to evaluate the quality and quantity of IgG, as well as the quality of the procedure for transferring passive immunity to the calf. Thus, the technology of working with colostrum is a key part of the prevention of diseases and mortality in young dairy calves.
