    Effect of energy deficiency during late pregnancy in chios ewes on free fatty acids, ß-hydroxybutyrate and urea metabolites
    (2006) Durak M.H.; Altiner A.
    Pregnant Chios ewes with high twin-lambing rates fed a low energy ration during the final periods of pregnancy were studied. The aim of this study was to determine whether pregnancy toxemia occurred in these ewes by monitoring the changes in the concentrations of serum free fatty acids (FFAs), plasma ?-hydroxybutyrate (?-HB) and urea. Thirty-eight Chios ewes were used. The animals were divided into 3 groups: pregnant normal energy (PNE), pregnant low energy (PLE), and non-pregnant normal energy (N-PNE). On day 105 of gestation, the animals were begun to be fed with the treatment rations. The feeding regime was continued until lambing. Blood samples were taken into tubes with and without anticoagulant from the jugular vein on days 120, 127, 134, 141, and 148 during gestation. The ewes in PLE had higher concentrations of FFAs on days 134 and 148 compared to those in PNE. ß-HB concentrations in PLE animals were always higher than those in PNE. No difference was found between PNE animals and N-PNE animals. Plasma urea concentration in PNE decreased on day 127, and then continuously increased to a significant level on day 148. It is concluded that an energy intake of greater than 10 MJ/kg ME should be ensured for pregnant ewes in late pregnancy, although an energy level of 8.0 MJ/kg ME does not cause a serious energy deficiency and does not cause pregnancy toxemia. © TÜBİTAK.

    The effects of age and gender on some biochemical serum parameters in Zom sheep raised in the vicinity of Karacadağ
    (Israel Veterinary Medical Association, 2015) Durak M.H.; Erkan R.E.C.; Çelik R.; Yokuş B.; Kurt D.; Gürgöze S.
    A hundred and seventy three clinically healthy Zom sheep aged 1-6 years and grazed on grassland under similar conditions in six villages of the Karacadağ and Ovabağ towns of the central, Bismil and Çınar districts of Diyarbakır province. The effect of gender in the evaluation for serum glucose, ?~glutamyltransferase, and alkaline phosphatase were observed for Zom sheep. The effect of age on the assessment made by taking into consideration the serum cholesterol, direct bilirubin, very low-density lipoprotein, alkaline phosphatase, ?~glutamyltransferase and direct bilirubin and high-density lipoprotein were also observed. In conclusion the age and gender of the Zom sheep needs to be taken into consideration in order to ensure an accurate clinical diagnosis and prognosis. © 2015, Israel Veterinary Medical Association.
