Bu çalışmada, klinik muayeneler sonucunda sağlıklı olduğu tesbit edilen 31 adcı Kangal Köpeği ile 40 adet Alman Çoban Köpeği'ne ait kan örneklerinde serum Alaninanıinotraiıs-feraz (ALT), Aspartataminotransferaz (AST), Ganıa-glutamiltransferaz (GGT) aktivileleri ile Total Protein, Albümin ve Glukoz düzeyleri belirlenmiştir. Ayrıca.bu biyokimyasal parametreler üzer inde ırkın ve cinsiyetin etkisi incelenmiştir. Araştırmada Kangal Köpeklerinin ortalama serum ALT, AST, GGT. T. Protein, Albümin ve Glukoz düzeyleri sırasıyla 35.64 UJ/L, 24.00 U/L, 5.23 IU/L. 5.63 g/dl, 3.99 g/dl ve 91.64 nıg/dl olarak tesbit edilmiştir. Alman Çoban Köpeklerinde ise aynı değerler sırasıyla 43.40 H I/l . 31.10 IU/L , 4.27 I U/L, 5.54 g/dl, 3.95 g/dl ve 93.97 mg/dl olarak saptanmıştır.

In this study, blood samples were taken (rom 31 Kangal Dogs and 40 German Sheepherd Dogs that were clinically diagnosed as healthy. These samples were measured tor sc¬rum ALT, AST and GGT activity as well as T. Protein, Albumin and Glucose levels. Furthermore, the effect of species and sex on these biochemical parameters were investigated. In this study, the avarages values of serum ALT, AST, GGT, T.Protcin, Albumin and Glu¬cose in Kangal Dogs were 35.64 IU/L, 24.00 IU/L, 5.23 IU/L, 5.63 g/dl, 3.99 g/dl and 91.64 ing/cll respectively. The avarage values'of serum parameters of German Sheepherd Dogs were 43.40 IU/L, 31.10 IU/L , 4.27 IU/L, 5.54 g/dl, 3.95 g/dl and 93.97 mg/dl respectively. The effects of sex on these blood parameters were found statistically unimportant except ALT in German Sheepherd Dogs and GGT in Kangal Dogs. When the serum enzyme levels of ALT, AST and GGT were compared in both dog groups, a statistically significant dillenince was found between species. It was also seen that species had no effects on serum glucose, T.Protein or Albumin levels.
