Data analyzed on productive and reproductive performances under present investigation in Deoni cattle depicted that the mean birth weight and weight at AFC were 20.81±0.21 (n, 140) and 223.64±3.59 (n, 101) kg,respectively. The AFC calculated in this study was 38.73±0.73 months. The overall mean lactation milk yield based on first 5 lactations was 779.27±18.31 kg with an average lactation length of 186.31±3.02 days. The present study also revealed that there was a significant increase in milk yield in second lactation than first lactation. The overall dry period and calving interval were 256.87±7.34 and 447.22±6.64 days, respectively. The overall mortality rate in Deoni cattle recorded was 2.17%. In view of reasonably better productive and reproductive performances in the present investigation than earlier studies there is a scope for further genetic improvement of the present Deoni herd.
