Özet
Bu araştırmada Kars bölgesinde yetiştirilen Tuj ırkı koyunlarda normal hematolojik parametreler ve bu değerler üzerine yaş, cinsiyet ve gebeliğin etkileri saptanmıştır. Intravenöz olarak alınan kanda eritrosit ve lökosit sayıları, hemoglobin, hematokrit değer ve lökosit tiplerinin yüzde oranları saptanmıştır. Merada otlayan 5-7 aylık dişi Tujlarda hemoglobin değeri ve eritrosit sayısı kapalı ortamda beslenen 2-3 aylık erkek tujlara göre belirgin bir şekilde yüksek (P< 0,01) azalmıştır. Lökosit sayısı gebelik döneminde her iki döneme göre daha az bulunmuştur, gebelik döneminde mm3 kanda 7,7 ± 1,9 x 103 , östrus öncesi 9,3 ± 1,9 x 103 , doğum sonrası 9,7 ± 2,5 x 103 . Lenfosit yüzdesi de gebelik döneminde ve doğum sonrası dönemde, östrus öncesi döneme göre belirgin bir şekilde artış göstermifltir (p< 0,001).
In this study some blood parameters and the effects of age, sex, housing system and pregnancy of Tuj sheep that have been bred in the Kars region of Turkey were researched and compared. The various blood parameters including the amount of haemoglobin, haematocrit value, erythrocyte and leukocyte count, and the differential percentage of white blood cells were determined from blood taken intravenously. The haemoglobin and erythrocyte values were found to be significantly (p < 0.05) higher in 5-7-month-old Tuj sheep grazing in an open field than in 2-3-month-old male Tuj sheep feeding in a closed system. The erythrocyte count was found to be higher in 2-3-month-old female Tuj sheep in comparison to males. The haemoglobin, leukocyte and haematocrit values were also higher in this group of animals, though this was not statistically significant. The erythrocyte, leukocyte, haemoglobin, haematocrit values and differential percentage of white blood cells were not different in 5-7-month-old male and female Tuj sheep grazing in an open area. The erythrocyte number decreased after parturition in respect to the oestrus and pregnancy period. This decrease was statistically significant. The erythrocyte values were 10.2 x 106 /mm3 before oestrus, 9.5 x 106 /mm3 during pregnancy and 8.2 x 106 /mm3 after parturition. The haemoglobin value decreased significantly (p < 0.05) during pregnancy. The leukocyte number was found to be less during pregnancy in comparison to other periods; it was 7.7 ± 1.9 x 103 /mm3 during pregnancy, 9.3 ± 1.9 x 103 /mm3 before oestrus, and 9.7 ± 2.5 x 103 /mm3 after parturation. The lymphocyte percentage increased significantly (p < 0.05) during the pregnancy period.
