Comparison of Serum IgG and Biochemical Parameters at the Postpartum Period in Dairy Cows and Heifers

Sütçü İnek ve Düvelerde Postpartum Dönem Serum IgG ve Biyokimyasal Parametrelerin Karşılaştırılması

Abstract

The aim of this study was to compare the levels of serum IgG and biochemical parameters at the postpartumperiod in dairy cows and heifers. Blood samples were taken immediately after birth from 48 cows, includingtwenty-four heifers and 24 cows which experienced two or more deliveries. Serum IgG level was determined by ELISAmethod and macromineral and biochemical parameters by using autoanalyzer. When serum biochemical parametersand IgG levels of heifers and cows were compared; in heifers, serum ALP, LDH and phosphorus levels were significantlyhigher (P<0.05) and IgG and Mg levels were significantly lower (P<0.05). In conclusion, it is determined thatthere are significant differences in serum immunoglobulin G, macromineral and some biochemical parameters betweenheifer and cows at the postpartum period and that it would be useful to consider these changes in postpartum period indairy cows.
