Assessment of triacylglycerole level of hepatic cells and total bilirubin and glucose of serum in hybrid dairy cows slaughtered in Ahwaz abattoir

Fatty liver is a major metabolic disorder that affects approximately half of multiparous dairy cows mildly or severely in early lactation. The purpose of this study was to compare the hepatic triacylglycerols (TAG) with total bilirubin and glucose of serum. For this purpose, 203 blood and liver samples were collected from the indigenous hybrid cows immediately after slaughtered. The sampled cows were divided into four groups according to their pregnancy status: 1-8 months pregnant, 8-9 months pregnant, less than a month after parturition and more than a month after parturition. The percentage of TAG in liver samples and the amounts of total bilirubin and glucose in blood were measured. All liver samples collected in this study showed percentage of fatty infiltration. The accumulation of fat in the liver of cows that had recently given birth was significantly (p
