    Incidence, early diagnosis of subclinical ketosis and determination of liver dysfunctions in cows in Bursa region
    (Uludağ Üniversitesi, 1999) Kennerman, Engin; Uludağ Üniversitesi/Veteriner Fakültesi/İç Hastalıkları Anabilim Dalı.
    Two hundred forty four cows and heifers in Bursa Region were divided into four groups in prepartum and postpartum periods in this study. Total leucocyte counts, haematocrit values, senım Hydroxybutyrate concentrations and level of ketone bodies in milk and/or urine were determined in all groups. Incidence of subclinical ketosis was found as 16.39 % and the highest incidence was observed within the first month of lactation (28.81 %). Alsa, the incidence in prepartum period was found as 16.21%. Serum glucose, GLDH, AST, ALT, ALP, GGT, LDH, total bilirubin, direct bilirubin, indirect bilirubin, total protein, albumin and globulin levels were estimated in 20 cows with Hydroxybutyrate concentrations less than 1.00 m·mol/I and 45 cows with Hydroxybutyrate concentrations higher than 1.00 mmol/I. Serum Hydroxybutyrate concentrations, GLDH, LDH, total bilirubin, indirect bilirubin (p<0.001), direct bilirubin and albumin !evels (p<0. 05) were found statistically different in cows with clinical ketosis compared with controls. Serum Hydroxybutyrate concentrations in ketosis group were positively correlated with serum GLDH, AST, (p<0.001), total bilirubin and indirect bilirubin (p<0.01) !evels. Asa result it was concluded that economic losses can be minimized by early diagnosis of ketosis by estimating serum Hydroxybutyrate concentrations periodically during the last month of gestation and within three months after calving in large farms with high yielding dairy cows.
