Serum IgG1 concentrations in calves born to mothers consuming 2.5% BW/d alfalfa hay grown in a field not fertilized with Se (0 g Se/ha; Control cows) or harvested from fields fertilized with sodium selenate at application rates of 45.0 (Med-Se cows) or 89.9 (High-Se cows) g Se/ha for 10 wk ± 16 d before their expected calving date. Blood was collected at birth and at 12, 24, 36, and 48 h. There was a time effect (P = 0.01). Immunoglobulin G1 concentrations were not detectable at birth and increased from 12 h to 24 h (P < 0.001) and remained similar at 36 (P = 0.99) and 48 h (P = 0.13). There was no effect of Se treatment (P = 0.43) nor Se treatment × time interaction (P = 0.55).
