چکیده
1 Interpretative Summary: Effect of oral calcium supplementation on early lactation health 1 and milk yield in commercial dairy herds. By Oetzel and Miller, page 000. Low blood 2 calcium often occurs in older cows around calving and impairs subsequent health and milk yield. 3 Second lactation or greater cows in 2 commercial dairies with effective milk fever prevention 4 were divided into control (no oral calcium boluses) and supplemented groups (cows given 2 oral 5 calcium boluses after calving). Lame cows supplemented with oral calcium had improved early 6 lactation health, and cows with higher milk yield in the previous lactation had improved early 7 lactation milk yield when given oral calcium boluses. Targeted groups of cows can benefit from 8 oral calcium bolus supplementation, even in herds with very little hypocalcemia. 9

Gild, C. 16 INTRODUCTION Parturient paresis is a metabolic disorder occurring close to parturition especially in high producing dairy cows. The disease is characterized by a rapid decline in blood calcium (Ca) concentrations. Nearly all mature cows experience some degree of hypocalcemia during the first day after calving as the intestine and bone adapt to the Ca demands of lactation (1). In som...
