The dose of IgG1 ingested by calves over the 48-h time period from dams fed their respective alfalfa hay treatments did not significantly differ among treatment groups. Calves were 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. There was a time effect (P = 0.005). The dose of IgG1 ingested increased from 12 h to 24 h (P = 0.002) and then from 24 h to 48 h (P = 0.007). There was no effect of Se treatment (P = 0.39) nor Se treatment × time interaction (P = 0.42).
