Table 3.
Concentrations of fatty acids (FA) and immunoglobulin G (IgG) in cows and their calves upon calving. Cows were supplemented with Ca soaps of soybean oil (CSSO; n = 52) or prilled saturated fat (CON+; n = 52) during the last trimester of gestation. Values reported are least square means ± standard error. Adapted from Brandão et al. [42].
