    Changes in Serum Mineral Concentrations, Biochemical and Hematological Parameters in Horses with Pica
    (Humana Press Inc, 2011) Aytekin, Ismail; Onmaz, Ali Cesur; Aypak, Serap Unubol; Gunes, Vehbi; Kucuk, Osman
    The aim of this study was to compare hematological, some biochemical parameters, and serum trace element concentrations in horses with or without pica. Fifteen horses with pica (group I) and another 15 healthy horses without pica (group II) were used. The hematological parameters were not changed between the two groups. In group I, hemoglobin values were lower than those of group II. However, the difference in hemoglobin values between the two groups was not significant (P > 0.05). Serum iron and copper concentrations and the copper/zinc ratio were lower in group I than those of group II (P < 0.05). The other biochemical parameters were not found to be statistically different between the two groups (P > 0.05). It was concluded that serum iron and copper deficiency may play an important role for the etiology of pica in horses. Prophylactic use of iron and copper supplements in horses may be beneficial to prevent pica.

    Levels of selected minerals, nitric oxide, and vitamins in aborted Sakis sheep raised under semitropical conditions
    (Springer, 2011) Aytekin, Ismail; Aypak, Serap Unubol
    The serum levels of calcium, phosphorus, magnesium, copper, zinc and iron and of nitric oxide, retinol, and beta-carotene were determined in Sakiz ewes that had experienced an abortion and in healthy controls. Ten healthy and 25 aborted Sakiz sheep were selected from Afyon zone in western Turkey. Their ages ranged between 2 and 4 years weighing between 40 and 60 kg at the time of experiment. All of the abortions occurred in October. The concentrations of retinol, beta-carotene, phosphorus, and zinc were significantly lower and those of calcium and nitric oxide were increased in aborted ewes relative to healthy controls. The serum levels of iron, copper, and magnesium were not significantly different among the two groups. In conclusion, abortion is an important problem in commercially important species of ruminants in many regions in the tropics including of western Turkey. Deficiencies of retinol, beta-carotene, phosphorus and zinc, and the increase of calcium and nitric oxide concentration may play an important role in the etiology of abortion in ewes. Prophylactic measures such as vitamin and mineral supplementation may be of help to prevent or reduce the incidence of abortion in sheep.

    TRACE ELEMENTS AND BIOCHEMICAL AND HAEMATOLOGICAL PARAMETERS IN COWS WITH DOWNER SYNDROME
    (Natl Veterinary Research Inst, 2011) Onmaz, Ali Cesur; Aytekin, Ismail; Aypak, Serap Unubol; Gunes, Vehbi; Kucuk, Osman; Ozturk, Aliye Sagkan
    The objective of this study was to investigate the serum concentrations of iron, manganese, cobalt, copper, zinc, and copper/zinc ratio in Downer cows. The study was performed on 20 recumbent Downer cows and 20 healthy cows. The serum concentrations of iron (P=0.002) and copper (P=0.035) were lower in Downer cows compared with the healthy cows. Serum zinc concentrations, although not significantly (P=0.162), were also lower in Downer cows compared with the healthy cows. Cows with Downer syndrome had greater concentrations of serum AST (P<0.001), LDH (P=0.003), and CK (P<0.001). Other biochemical parameters remained unchanged. RBC (P=0.026), Hb (P=0.029), and MCV (P<0.001) in cows with Downer syndrome had lower values compared with those of healthy ones. However, WBC in cows with Downer syndrome had greater values (P<0.001) compared with those of healthy ones. Other haematological parameters remained similar between Downer cows and healthy cows. It was concluded that serum iron and copper concentrations may play an important role for the aetiology and/or pathogenesis of Downer cows. These elements may be supplemented for the prevention and therapy of recumbency in cows.
