[The hemoglobin concentration in the blood of dairy cattle of different breeds and their offspring during the peripartum period].
Blood samples taken repeatedly from dairy cows on pasture (50 Holstein-Friesian) and then from 181 cows and their newborn calves within 5 to 10 min after birth were used for measurement of haemoglobin content (Hb). Hb decreased with ongoing lactation and pregnancy, increased several weeks before parturition and reached its highest value shortly after birth. There was some individual, breed and age specificity of Hb in dairy cows. Assisted calvings using marked traction resulted in no difference in Hb values of the cows when compared to other calvings; whereas the calves' Hb values were smaller and the difference between calf Hb and cow Hb was greater. A strong correlation between Hb of the cow and Hb of the newborn calf and the difference Hb calf-Hb cow could be found.
