Performance of jersey crossbred cattle in the North-Western Zone of Tamil Nadu under semi-arid climatic conditions

Abstract

Data on the production and reproductive performance of 50 Jersey crossbred cows, raised at the Livestock Farm Complex of the Veterinary College and Research Institute in Namakkal, Tamil Nadu, over a period of 10 years (2014-2024), were collected from existing farm records. This data was analyzed to evaluate the production and reproductive metrics of Jersey crossbred cattle. The means±S.E for 305 days milk yield and lactation milk yield were 2463.26±56.27 and 2585.21±72.13 respectively. The means ± S.E for lactation length, service period, calving interval, dry period, Gestation period and age at first calving were 324.11±20.14, 150.87±22.45, 462.65±12.07, 137.06±15.45, 283.75±7.34 and 910.09±20.15 days respectively. The number of services required per conception were 2.87±0.37. The findings from this study indicate that Jersey crossbred cattle perform well in the northwestern zone of Tamil Nadu, even under semi-arid climatic conditions.
