Blood metabolite concentrations and body condition score in relation to postpartum resumption of ovarian cyclicity in crossbred cows

Abstract

Apparently healthy crossbred cows (20) of first to fourth parity with normal calving history and free from any immediate post-parturient complications were selected to study the body condition score (BCS) and certain blood metabolite for establishment of cyclicity during postpartum periods. The cows were divided equally into 2 groups– Gr A (cows exhibited oestrus within 60 days postpartum (cyclic)) and Gr B (cows did not exhibit oestrus within 60 days postpartum (non-cyclic)). The study revealed that the BCS, level of serum total protein, cholesterol, BUN, calcium, phosphorus and magnesium differed significantly at different days of postpartum, i.e. day 0, 15, 30, 45, 60 and between the groups. The BCS, level of serum glucose, total protein, cholesterol, BUN, calcium, phosphorus and magnesium had a positive relation with respect to the postpartum cyclicity of the crossbred cows.
