We investigated if andto which extent the sera profiles were correlated with antibody levels in thecolostral milk administered, with GGT activity and with total plasma proteincontent. Due to the assays’ high sensitivity, traces of IgG and IgM in calf seracould be determined prior to the first uptake of the foremilk. Throughout thecolostrum administration period until the 12th living hour, IgG and IgM levelsremarkably increased (P}, year = {2009}, journal = {Berliner und Münchener Tierärztliche Wochenschrift}, volume = {116}, pages = {44-52}, month = {02/2009}, publisher = {M. & H.
