The present study was conducted on correlation between reproductive traits (calving interval) with productive traits (dry period) in Gangatiri breeds. The data for study were collected from history sheet maintained at livestock cum agricultural farm, Arajiline, Varanasi -221305 (Uttar Pradesh) for period 2000-2017. The reproductive trait selected from history was first, second and third lactation calving intervals with the productive traits were second, third and fourth lactation dry period. The mean for first, second and third calving interval were 468.2, 404.175 and 397.625 days respectively. The mean value of productive traits such as second, third and fourth lactation dry period is 174.15, 148.63 and 157.67 respectively. Data were respectively were analyzed statistically to determine the correlation between reproductive with productive traits. The correlation between first calving interval with second dry period were positively significant (0.057), second calving interval with third dry period were negatively non-significant (-0.057) and third calving interval with fourth dry period were positively significant (0.366).
