Background: The aim of this study was to estimate the serum biochemical (glucose, cholesterol, total protein, calcium, phosphorus and magnesium) and hormonal constituents (estrogen and progesterone) in female Manipuri pony mares during the different days of oestrous cycle. Methods: A total of 50 numbers of blood samples were collected from 10 numbers of apparently healthy, non-pregnant on the different days of oestrous cycle i.e. day 0, 4, 8, 14 and 18 by using commercial diagnostic kits. Result: The mean serum levels of glucose, cholesterol and phosphorus were found to be non-significant on the different days of oestrous cycle whereas the mean serum level of total protein and calcium was found significantly different (P less than 0.01). The serum magnesium level differed significantly (P less than 0.05) amongst the different days of oestrous cycle. Both estrogen and progesterone were also found to be significant (P less than 0.01) between the different days of oestrous cycle. The results showed significant influence on serum biochemical and hormonal assay during different days of oestrous cycle in female Manipuri pony.
