产后灌服丙二醇防控奶牛产后能量负平衡在一些规模化奶牛场已得到了应用。为了进一步研究奶牛产后灌服保健技术，本试验研究了产后灌服丙二醇与钙磷镁合剂+复方口服补液盐对奶牛四项血液生化指标的影响。分娩后第18天的测定结果表明，试验Ⅰ组（灌服丙二醇）和试验Ⅱ组（灌服钙磷镁合剂+复方口服补液盐）的血酮（β-羟丁酸）含量差异显著（P＜0.05）。与灌服丙二醇相比，灌服钙磷镁合剂+复方口服补液盐不仅在预防奶牛隐性酮病方面效果显著，在预防产后低血钙症方面也有一定的实际意义。

Feeding propylene glycol to postpartum dairy cows is the effective measure to control negative energy balance, and has been taken by some large-scale dairy farms. The purposes of the paper are to study and compare the inlfuence of feeding propylene glycol and the mixtures of calcium, phosphate and magnesium with oral rehydration salts on four biochemical indexes of postpartum dairy cows. The results indicated that the difference in the content of blood ketone (β-hydroxybutyrate)between group 1 (feeding propylene glycol) and group 2(feeding calcium, phosphate and magnesium with oral rehydration salts) was striking(P<0.05), and illustrated that the preventative effect of feeding calcium, phosphate and magnesium with oral rehydration salts was very superior to feeding propylene glycol. What’s more, feeding calcium, phosphate and magnesium with oral rehydration salts can also play a role in the prevention of postpartum hypocalcemia.
