Haematological profles of Indonesian fat‑tailed sheep under diferent physiological conditions

The aim of this research was to evaluate the efect of sex, age, feed and physiological conditions on the haematological
profles of Indonesian fat-tailed sheep. A total of 32 healthy Indonesian fat-tailed sheep in diferent physiological states (i.e. suckling lambs/weaners aged 1–5 months, postweaning lambs aged 6–8 months, lactating ewes, rams, and pregnant ewes) were used in this study. Blood samples were collected from the jugular vein and then transferred into tubes for haematological analysis. The results revealed the following: RBCs, 7.09±0.52 million µL−1; HCT, 46.76±4.30%; Hb, 9.83±0.57 g dL−1;
MCV, 69.88±5.48 fL; MCH, 14.94±0.71 pg; MCHC, 24.29±1.36 g dL−1; WBCs, 5.60±1.24 thousand µL−1; percentage
of neutrophils, 58.30±7.31%; percentage of lymphocytes, 41.63±7.31%; and N/L ratio, 0.18±0.05. The physiological
status of the sheep afected RBCs, Hb, HCT and MCH (P<0.05). The sex, age, feed and physiological status of the animals
should be considered in the interpretation of haematological profles in Indonesian fat-tailed sheep.
