Calcium metabolism in cows receiving an intramuscular injection of 1,25-dihydroxyvitamin D₃ combined with prostaglandin F₂α closely before parturition

Calcium metabolism in cows receiving an intramuscular injection of 1,25-dihydroxyvitamin D₃ combined with prostaglandin F₂α closely before parturition

To determine the effect of exogenous 1,25-dihydroxyvitamin D₃ [1,25(OH)₂D₃] combined with induced parturition on calcium (Ca) metabolism, cows received a single intramuscular injection of 1,25(OH)₂D₃ and prostaglandin F₂α (PGF₂α) closely before calving. Ten late-pregnant, multiparous Holstein cows w...

Zusammenfassung:To determine the effect of exogenous 1,25-dihydroxyvitamin D₃ [1,25(OH)₂D₃] combined with induced parturition on calcium (Ca) metabolism, cows received a single intramuscular injection of 1,25(OH)₂D₃ and prostaglandin F₂α (PGF₂α) closely before calving. Ten late-pregnant, multiparous Holstein cows were assigned to 1,25(OH)₂D₃ group (five treated with both 1,25(OH)₂D₃ and PGF₂α) and control group (five treated with PGF₂α). 1,25(OH)₂D₃ group showed an increase in plasma Ca concentration around parturition, whereas control group revealed a decrease in plasma Ca level. Plasma Ca concentration in 1,25(OH)₂D₃ group were significantly higher than that in control group during -0.5 to 3 days after parturition.
