ABSTRACT
Blood profile changes during various reproductive states, it is imperative to study hematological constituents during these states. The present project was therefore designed to investigate various haematological values of Sahiwal cows during synchronization programme by using Heatsynch protocol. 5 ml blood with anticoagulant was collected from six cows aseptically by jugular vein puncture on day 0,7,10 & 20. Among haematological parameters TLC (thousands/ µl), TEC (millions /µl), Hb (g %), HCT (%), MCV (fl), MCH (pg) and MCHC (g/dl) were evaluated by using an automatic blood analyzer. The study indicated significant decrease in the TEC, Hb and HCT at the time of induced estrus from the day before start of treatment. The mean platelet counts vary non- significantly during the experiment. The mean values of erythrocytic indices (MCV & MCHC) highly significant (p<0.01) at day of induced estrus. Hematological parameters can be an important tool for the assessment of reproductive behavior in Sahiwal cows.
