Effect of multiple i.v. injections of cyanocobalamin and butaphosphan administered between 1 and 2 wk antepartum (a.p.) on the serum total bilirubin and calcium concentrations of dairy cows. Forty-five late-gestation Holstein-Friesian cows were allocated randomly to 1 of 3 groups (15 cows/group): group C6 (6 i.v. injections of cyanocobalamin and butaphosphan in the last 2 wk of gestation); group C3 (3 i.v. injections of cyanocobalamin and butaphosphan in the last week of gestation); group C0 (equivolume i.v. injections of 0.9% NaCl solution). Data are mean ± SD *P < 0.025 (Bonferroni adjusted) from group C0 at the same time. †P < 0.0167 (Bonferroni adjusted) from time = −14 d value.
