*ARAP VE YERLİ MELEZ ATLARDA BAZI KAN PARAMETRELERİ ÜZERİNE IRK, YAŞ VE CİNSİYETİN ETKİSİ

Bu çalışma, Yerli melez at ırkı ile safkan Arap atlarında organ fonksiyonları için spesifik olan bazı kan parametrelerinin belirlemesi ile ırk, yaş ve cinsiyet faktörlerinin bu parametreler üzerine etkisinin olup olmadığını ortaya koymak amacıyla yapılmıştır. Çalışmada hayvan materyalini, yaşları 1 - 12 (1-5 ve 6-12 yaş grubu) arasında değişen, 52 baş safkan Arap atı ve 50 baş Yerli Melez atı olmak üzere toplam 102 baş at oluşturmuştur. Hayvanlardan alınan kan örneklerinden sağlanan serumlarda AST, ALT, GGT, ALP, CK ve LDH enzim aktiviteleri ile glikoz, toplam kolesterol, trigliserid, toplam protein, albumin, globulin, üre, kreatinin, Ca, iP ve Mg düzeyleri belirlenmiştir. Bu çalışmada; Yerli Melez ve safkan Arap atlarında ırk faktörünün serum AST, ALT, CK ve LDH enzim aktiviteleri ile glikoz, üre, kreatinin, toplam kolesterol, trigliserid, toplam protein, albumin, globulin, Ca ve Mg düzeyleri üzerine etkili olduğu, ALP ve GGT enzim aktiviteleriyle iP düzeylerini etkilemediği saptanmıştır. Yerli melez atlarda incelenen biyokimyasal parametreler cinsiyet ve yaş faktöründen etkilenmemiştir. Arap atlarında serum CK, LDH, kreatinin, globulin, üre ve trigliserid düzeylerinin cinsiyet faktöründen, glikoz, toplam protein, Ca, iP ve Mg düzeylerinin hem cinsiyet hem de yaş faktöründen etkilendiği belirlenmiştir. Sonuç olarak, Yerli Melez ve Safkan Arap atlarına ait belirlenen bu serum biyokimyasal parametrelerinin referans değerler arasında olduğu, bu çalışma ile elde edilen verilerin hem klinisyenlere, hem de atlar üzerinde yapılacak araştırmalara katkı sağlayabileceği kanısına varılmıştır.

THE EFFECTS OF BREED, AGE AND SEX ON SOME BLOOD PARAMETERS IN ARABIAN AND LOCAL CROSS BREED HORSES

The aim of this study was to determine some blood parameters which are specific for some organ functions in local cross breed and Arabian horses as well as to determine whether breed, age and sex factors had effects on these parameters. Total 102 horses (1 to 12 years old: 1-5 and 6-12 years old); 52 Arabian and 50 local cross breed horses were used in this study. Serum AST, ALT, GGT, ALP, CK and LDH activities, glucose, total cholesterol, triglycerides, total protein, albumin, globulin, urea, creatinine, Ca, Pi and Mg levels were determined. In this study, serum AST, ALT, CK, LDH activities glucose, urea, creatinine, total cholesterol, triglycerides, total protein, albumin, globulin, Ca and Mg levels were influenced by breed, but not ALP, GGT activities and Pi levels in Arabian and local cross breeds. In local cross breed horses, the investigated biochemical parameters were not affected by sex and age. In Arabian horses, serum CK, LDH, creatinine, globulin, urea and triglyceride levels were affected by sex, and glucose, total protein, Ca, Pi and Mg levels were influenced by both sex and age. In conclusion, the analysed serum biochemical parameters of local cross breed and Arabian horses ranged within reference values. It is thought that the data obtained in this study may be useful for both clinicians and further researches that will be conducted on horses.
