Absorption efficiency of IgG1 from cow colostrum to calf serum for the first 12, 24, and 48 h was not significantly different 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 g Se/ha (High-Se cows) for 10 wk ± 16 d before their expected calving date. There was a time effect (P = 0.006). The absorption efficiency of IgG1 decreased from 12 h to 24 h (P = 0.04) and then from 24 h to 48 h (P = 0.001). There was no effect of Se treatment (P = 0.40) nor Se treatment × time interaction (P = 0.89).
