A study was carried out to assess the influence of pregnancy and postpartum period on various haematological parameters in NARI Suwarna ewes. A total of 30 NARI Suwarna ewes, aged two to three years, were selected for the present study and were divided into five groups, with six animals in each group, based on the presence or absence of pregnancy and also based on the presence of single and multiple foetuses.

The pregnant group animals showed significantly (P<0.05) lower haemoglobin concentration compared to nonpregnant group. Postpartum group animals showed significantly (P
