Description Information collected from 145 Nagori animals maintained at the Govemment Cattle Breeding Farm, Nagaur (from 1975 to 1992) was analysed by least-squares maximum likelihood technique. The least-squares means for production traits, viz. milk yield, lactation length, milk yield/day of lactation, milk yield/day of calving interval and dry period were 535.3± 18.13 kg, 267.7±7.77 days, 2.1±0,07 kg, 1.3±0.04 kg and 154.7±10,35 days, respectively, and for reproduction trailS, viz. service period, gestation period and calving interval, were 120.6±5.94, 283.6±0.85 and 423.2±11.22 days respectively. Average age at first calving was 1503.2±26.92 days and birth weight of calf was 16.9±0.16 kg. Parity had significant influence on all the traits except lactation length, gestation period and birth weight. Month of calving affected significantly aU the production traits except dry period and only service period among the reproduction traits. Period of calving had significant influence on milk yield traits, gestation period and calving interval. Male calves had significantly higher birthweight than the female calves. Repeatability and phenotypic correlations among different traits were also estimated.
