Reproductive performance of dairy cows is greatly affected by energy, protein and mineral profiles, which is also connected to postpartum anestrus. The present study was conducted during the period from December 2018 to May 2019 on 30 local x Holstein-Friesian crossbred lactating cows with parity 1-5 and body condition score of 2.0-3.5. This study aimed to compare serum glucose, cholesterol, triglycerides, total proteins, urea nitrogen, calcium, phosphorus and magnesium concentrations between anestrus and normal cyclic crossbred cows during 45 to 60 days postpartum. Automated biochemical analyzer was employed to measure these concentrations, using 15 cows in each group. The serum of postpartum anestrus cows contained significantly lower (P<0.05) concentrations of glucose, total proteins, calcium and magnesium compared to normal cyclic cows, while urea nitrogen concentration was significantly increased (P<0.05) in the postpartum anestrus cows. However, concentrations of other serum biochemical metabolites did not differ between cows of the two groups. These results suggest that blood glucose, total proteins, calcium, magnesium and urea nitrogen might have an effect on the cyclicity of Holstein-Friesian crossbred cows during 45 to 60 days postpartum. However, further studies are recommended to explore the underlying mechanism for the role of these metabolites in the cyclicity of postpartum cows.
