The importance of umbilical chord blood (UCB) study has been verified by the presence of hematopoietic stem cells in human UCB. The use of dogs as experimental model has provided usefull information for transplants in humans. However, despite the importance of UCB and dogs as experimental model, there are no studies concerning to the serum protein electrophoresis of the canine UCB. In this assay, UCB from 20 newborn dogs were collected, which was used for protein electrophoretic fractioning. The serum protein absolute medium values found for total proteins, albumine, alpha, beta and gamaglobulines in the UCB of newborn dogs where 3.09±0.59; 1.51±0.38; 0.87±0.17; 0.68±0.12 and 0.03±0.01, respectively. All values were presented bellow reported levels for adult animals, due to protein and its fractions passage mainly through the colostrum and due to hepatic immaturity. In all electrophoretic bandshifts from the canine UCB was observed a small curve between alphaglobulin 2 and betaglobulin 1, not reported in adult dogs. Therefore, in this assay quantitative differences were observed in the electrophoretic bandshift of serum proteins from dog’s UCB at birth, differing them, in this particularly, from dogs in others post-colostral life stages.
