Occurrence of anemia in suckling dairy calves up to 4 months old with regard to age and sex susceptibility was investigated in Urmia, Iran. From 25 dairy herds, 164 calves including 97 females and 67 males were selected. Five ml jugular vein blood was collected from calves into 2 ml with EDTA and 3 ml without EDTA tubes. Blood parameters were evaluated for hematocrit (PCV), hemoglobin (Hb), erythrocytes (RBC), leucocytes (WBC), total plasma protein, iron (Fe), total iron banding capacity (TIBC), neutrophils, lymphocytes, MCV, MCH, and MCHC. Anemia was classified according to the PCV values, over 24%, 20-23.99%, 12-19.99% and less than 12% as normal, mild, moderate and severe anemia. The percentage of anemia in calves was 17.7% including 14% mild and 3.7% was moderate anemia (P<0.05). The percentage of moderate and mild anemia in female calves was greater than in male calves but the differences was not significant. Significant age differences (P<0.05) were observed at 3 months of age for moderate and up to 2 months old for mild anemia. Mean Hb, RBC, Fe, lymphocytes, TIBC and MCV decrease by increasing the anemia symptom. Mean WBC, neutrophils, MCHC and protein increase by increasing the anemia sign. The differences were significant (P<0.05) only for PCV, Hb, RBC and MCHC. In conclusion, calves reveal a mild anemia, which is not related to Fe deficiency. Gender difference was not obvious in anemia while the age of 3 months is the critical age for moderate anemia occurrence in Urmia dairy calves that prevention procedures must be considered.

DÖRT AYLIK SİYAH ALACA IRKI BUZAĞILARDA ANEMİNİN İNCELENMESİ

Öz

Emme döneminde olan 4 aylık buzağılardaki anemi oluşumundaki yaş ve cinsiyet yatkınlığı Urmia, İran’da incelendi. 25 sürü içerisinden, 97’si dişi ve 67’si erkek olmak üzere 164 buzağı seçildi. Jugular venadan 2 ml’si EDTA’lı ve 3 ml’si EDTA’sız tüplere konulmak üzere 5 ml kan alınmıştır. Kan parametrelerinden; hematokrit (PCV), hemoglobin (Hb), eritrositler (RBC), lökositler (WBC), total plazma protein, demir (Fe), total demir bağlama kapasitesi (TIBC), nötrofiller, lenfositler, MCV, MCH ve MCHC incelendi. Anemi PCV değerleri %24’ün üstünde normal, %20-23,99 arasında az, %12-19,99 orta, %12’den düşük şiddetli anemiye göre sınıflandırılmıştır. Buzağılardaki aneminin oranı %14’ü az ve %3,7’si orta dereceli anemi olacak şekilde %17,7 olarak belirlendi (P < 0,05). Orta ve az dereceli aneminin oranı dişi buzağılarda daha yüksek olmasına rağmen bu fark istatistiki açıdan önemli değildir. Yaşa bağlı belirgin değişimler (P < 0,05) orta dereceli anemilerde 3 aylıklarda ve az dereceli için ise 2 aylık buzağılarda gözlenmiştir. Aneminin semptomlarının artması sayesinde ortalama Hb, RBC, Fe, lenfosit, TIBC ve MCV azalır. Değişimler sadece PCV, Hb, RBC ve MCHC için belirgindi (P < 0,05). Sonuç olarak buzağılarda Fe yetmezliği ile bağlantılı olmayan az dereceli anemi açığa çıkmaktadır. Urmia’daki buzağılarda cinsiyetin anemi oluşumu üzerine etkisinin belirgin olmadığı; orta dereceli anemi için 3 aylık yaşın kritik olduğu ve buna ilişkin önlemlerin alınması gerektiği sonucuna ulaşılmıştır
