Blood concentration of proteins, bilirubin and glucose in cows with left displaced abomasum

Abstract

The concentration of total proteins, albumin, total bilirubin, and glucose were examined in the blood of healthy cows and those with left displaced abomasum. Significant digressions from physiological values in cows with left displaced abomasum were established in proteinemia (x = 87.92 g/l) and in bilirubinemia (x = 10.29 μmol/l). Hyperproteinemia indicates chemoconcentration in the diseased animals, which is also indicated in significantly higher concentrations of albumin in the diseased in comparison with the healthy animals (x = 41.94 - 3.5 : 36.89 - 3.95 g/l). The higher values for glucemia in the diseased against the healthy animals (x = 2.628 : 2.203 mmol/l) could indicate disrupted function of B-cells of the endocrine pancreas. This data can come in useful in setting the diagnosis, but it also has no less importance in the determination of the prognosis for the disease. Determining the liver function during the disease should contribute to the better knowledge of its role in the degree of the occurrence of this health disorder, as well as the outcome of the disease itself. This is of particular importance having in mind that displaced abomasum most frequently occurs in the early stage of lactation, when a negative energy balance is already present. This state is conducive to the occurrence of fatty liver, and that is why displaced abomasum can contribute even further to the process of fat accumulation, having in mind that diseased animals consume significantly smaller quantities of feed.

U krvi zdravih krava i onih obolelih od dislokacije sirišta na levo, ispitivana je koncentracija ukupnih proteina, albumina, ukupnog bilirubina i glukoze. Značajna odstupanja od fizioloških vrednosti kod krava sa dislokacijom sirišta ustanovljena su u proteinemiji (x = 87,92 g/l) i bilirubinemiji (x = 10,29 _mol/l). Hiperproteinemija ukazuje na hemokoncentraciju u obolelih životinja, o čemu svedoči i značajno veća koncentracija albumina kod obolelih u odnosu na zdrave životinje (x = 41,94±3,5:36,89±3,95 g/L). Veće vrednosti glikemije u obolelih u odnosu na zdrave životinje (x = 2,628:2,203 mmol/l) mogu da ukažu na poremećenu funkciju B-ćelija endokrinog pankreasa. Ovaj podatak može biti koristan pri postavljanju dijagnoze, ali ne manji značaj ima i pri proceni prognoze bolesti. Utvrđivanje funkcije jetre tokom bolesti treba da doprinese boljem poznavanju njene uloge u stepenu nastanka poremećaja zdravstvenog stanja kao i samom ishodu bolesti. Ovo je posebno značajno ako se ima u vidu da se dislokacija sirišta najčešće pojavljuje u ranoj fazi laktacije, kada inače postoji negativan bilans energije. Ovo stanje predisponira nastajanje zamašćenja jetre pa zbog toga dislokacija sirišta može još više da doprinese procesu zamašćenja jer bolesne životinje konzumiraju značajno manje količine hrane.
