Limited literature is available on the consequences of postpartum low blood calcium (Ca) concentration in crossbred cows. The research aimed to investigate the correlation between postpartum serum Ca levels and various parameters, including milk yield, serum energy metabolites, milk somatic cell count, and reproductive factors in crossbred cows. Following parturition, a total of 45 potential high‐yielding F2 (HF × Sahiwal; Genotype: 75:25) dairy cows were enrolled . These cows were categorized based on plasma calcium concentrations into three groups: a low calcium group (Ca‐L) with a calcium concentration of <5 mg/dL, a medium calcium group (Ca‐M) with a calcium concentration ranging from 5 to 8.5 mg/dL, and a high calcium group (Ca‐H) with a calcium concentration exceeding 8.5 mg/dL. The study parameters were measured over an 8‐week period. The results indicated that overall milk yield and blood glucose were significantly higher in the Ca‐H group compared to Ca‐M and Ca‐L (p < .01). Blood cholesterol was significantly higher in Ca‐M (p < .01), while blood triglyceride was significantly lower in both Ca‐M and Ca‐H. Overall, blood cortisol did not show a significant change between these groups (p < .01); however, progesterone levels were higher (p < .01) in Ca‐M and Ca‐H cows. Furthermore, somatic cell count (SCC) significantly (p < .01) decreased in cows with Ca‐H compared to Ca‐L. Additionally, postpartum oestrous interval and interestrus interval decreased significantly (p < .01) in Ca‐M and Ca‐H compared to Ca‐L. These findings suggest that cows with blood calcium levels exceeding 8.5 mg/dL exhibited significantly higher milk yield, blood metabolite levels, a lower likelihood of subclinical mastitis, and earlier reproductive activity after calving.
