| Outline of Final Research Achievements |
We evaluated the cultivation and feeding methods of high chlorine (Cl) forage for prevention of hypocalcemia. We evaluated fertilizer application method to reduce DCAD value in forage crop efficiently. We found DCAD value was reduced by chloride fertilizer, and the amount of chloride fertilizer significantly affects DCAD value rather than the timing of chloride fertilization. The Cl content did not have an apparent effect on the palatability of forage. It is showed that feeding of high Cl forage in dairy cow increased Cl absorption in the intestine and might improve Ca metabolism around parturition.
