abstract = "The aim of this study was to determine the influence of an energy supplement on the basis of propylene glycol on the values of metabolic profile parameters in periparturient cows. Fifteen days before calving, 40 cows were selected and divided into two groups: control (n=20) and experimental (n=20). From day 15 before to day 30 after calving, the experimental group of cows received an energy supplement based on propyleneglycol added in food ('OSIMOL', Veyx-Pharma GmbH, Germany). Blood samples were taken 15 days before and 10 days after calving. Concentrations of glucose and betahydroxybutyric acid (BHBA) were determined immediately after blood was taken. Concentrations of total protein, albumin, urea and total bilirubin were determined in the blood serum. There was no significant difference in the average values of the measured parameters between the control and the experimental group of cows. After parturition glycemia in cows of the control group was lower than physiologically acceptable (x=1.93±0.43 mmol/L), and glucose in cows of the experimental group was at the upper physiological limit (x=3.13±0.33 mmol/L) and signicantly higher (p lt 0.001) than in the control group. The concentration of BHBA in cows that received the energy supplement ('OSIMOL') was 0.40±0.12 mmol/L, while in the control group of cows it was significantly higher (p lt 0.001) and stood at 0.88 ±0.39 mmol/L. Furthermore, the concentration of total bilirubin in the cows of the experimental group was within the physiological range (x = 4.09± 1.42 μmol/L), while in the cows of the control group it was significantly higher (p lt 0.05) and stood at 10.19±5.16 μmol/l., Cilj istraživanja izloženog u ovom radu je bio da se utvrdi uticaj energetskog dodatka na bazi propilen-glikola na vrednosti parametara metaboličkog profila krava u peripartalnom periodu. Petnaest dana pre očekivanog teljenja odabrano je 40 krava, koje su podeljene u dve grupe: kontrolnu (n=20) i oglednu (n=20). Kravama u oglednoj grupi u periodu od 15 dana pre do 30 dana posle teljenja u hranu je dodavan preparat na bazi propilen-glikola ('OSIMOL', Veyx-Pharma GmbH, Nemačka) u dnevnoj količini od 200 grama. Uzorci krvi su uzeti 15 dana pre i 10 dana nakon teljenja. Neposredno nakon vađenja krvi, u uzorcima pune krvi, određivana je koncentracija glukoze i betahidroksibuterne kiseline (BHBA). U uzorcima krvnog seruma određivana je koncentracija ukupnih proteina, albumina, ureje i ukupnog bilirubina. U antepartalnom periodu, kod krava kontrolne i ogledne grupe, nisu ustanovljene značajne razlike između prosečnih vrednosti ispitivanih parametara metaboličkog profila. Posle partusa kod krava kontrolne grupe koncentracija glukoze je bila niža od fiziološki prihvatljive (x=1,93±0,43 mmol/l), dok je kod krava ogledne grupe glikemija bila na gornjoj fiziološkoj granici (x=3,13±0,33 mmol/l) i statistički značajno viša nego kod kontrolne grupe (p lt 0,001). Koncentracija BHBA kod krava koje su dobijale energetski dodatak ('OSIMOL') iznosila je 0,40±0,12 mmol/l, dok je kod krava kontrolne grupe bila značajno veća (p lt 0,001) i prosečno iznosila 0,88±0,39 mmol/l. Osim toga, kod krava ogledne grupe koncentracija ukupnog bilirubina je bila u granicama fizioloških vrednosti (x= 4,09 ± 1,42 μmol/l), dok je kod krava kontrolne grupe ta vrednost bila značajno veća (p lt 0,05) i iznosila je 10,19±5,16 μmol/l.",
