Popis: Natural autoantibodies (NAAb) have been found in plasma and milk of dairy cows. Natural autoantibodies maintain homeostasis and may prevent infections. The objective of this study was to evaluate the relationship between concentration of plasma free fatty acid (FFA) and the levels of NAAb in plasma binding glutamate dehydrogenase (GD) and carbonic anhydrase (CA) in cows 2 weeks after calving. In total, 55 Holstein-Friesian dairy with 60-d dry period lengths and fed 2 early lactation diets (glucogenic or lipogenic). Blood was sampled at week 1 and 2 after calving. Result showed that from week 1 and 2 relative to calving, levels of IgG and IgM binding CA were positively related with concentration of FFA in plasma. Levels of IgM binding GD were negatively related with concentration of FFA in plasma. It is concluded that IgG and IgM binding CA in plasma might be an indicator for energy status and reflect metabolic status in dairy cows 2 weeks after calving.
