Colostrum silage is an anaerobic fermentation methodology of excess farm colostrum used to conserve and provide as milk replacement for calves. The present study aimed to evaluate the levels of immunoglobulins present in bovine colostrum silage and its absorption by newborn calves. The concentration of immunoglobulins was determined in fresh colostrum and colostrum silage stored for 12 months. The absorption of immunoglobulins by calves was assessed immediately after birth and 24 h after colostrum silage intake. The immunoglobulin levels were evaluated by ELISA . The results highlighted that colostrum silage kept similar levels of immunoglobulins as the ones in colostrum in natura , and can be transferred to newborn calves with similar amounts to calves fed with colostrum in natura . It is concluded that colostrum silage keeps viable immunoglobulins, and is able to transfer passive immunity to newborn calves.
