Assessment of Haematological and Biochemical Changes in Postpartum Anoestrous Ongole Cattle of Andhra Pradesh

The present study was aimed to assess the hemato-biochemical changes in postpartum anoestrous Ongole cattle. A total of 12 animals of same age and body weight were randomly selected and divided in to two groups, G I: postpartum anoestrous (PPA, n=6) and G II: cyclic animals (n=6). Blood samples were collected by jugular vein puncture and analyzed for hematological parameters. Further, the serum was separated from another aliquot of blood sample and utilized for biochemical parameters. The mean RBC, Hb, PCV, glucose, total protein and cholesterol values were significantly (p<0.05) lower in PPA compared to cyclic animals. In contrast, no significant (p>0.05) difference was observed in MCV, MCH, MCHC, WBC, lymphocyte and monocytes between groups. From the present study, it was concluded that hematological and biochemical parameters are reliable indicators of postpartum anestrus.
