Abstract: The observation on relationship between some productive and reproductive traits of Jersey (J) x Red Sindhi (RS) cows. The data for the study were collected from 50 history sheets records maintained in the department of animal husbandry, Sam Higginbottom Institute–Deemed-to-be-Allahabad University, dairy farm Allahabad for the period from 1944 to 1960 Animals were managed by skilled persons under similar management condition. The mean of first second and third lactation length, lactation yield were 370.200 days, 474.320 days, 368.320 days, 1887.273 kg, 1975. 961 kg, and 1731.426 kg respectively. The mean of age at calving, first and second calving interval were 983.86 days, 436.44 days and 454.68 days respectively. There was high degree correlation between productive and reproductive traits. A total of 18 correlation coefficients were collected for determining the correlation between lactation length, lactation yield and age at calving, first and second calving interval. From 18 correlation, 10 values were found significant and 8 values were found non-significant.
