Abstract: Dairy cow fertility control depends heavily on nutrients, which are necessary for the growth and development of reproductive organs. Any deficiency may impair the reproductive organ's cellular metabolism and enzymatic function, perhaps leading to concurrent reproductive issues. The goal of the current study was to evaluate the correlation between the blood biochemical and hormonal profiles of indigenous non-descript female cattle in Manipur at various stages of their reproductive cycles. From ten experimental animals, a total of thirty blood samples were collected at days 0, 10, and 18 of the oestrous cycle. Several biochemical indicators, including glucose, cholesterol, calcium (Ca), phosphorous (P), zinc (Zn), estrogen, and progesterone were measured from the serum. Blood glucose, zinc, estrogen, and progesterone levels varied significantly (p<0.01) between the various oestrous cycle days, according to the current study. Blood cholesterol, calcium and phosphorus levels at various oestrous cycle days did not significantly differed according to analysis of variance.
