The present study was carried out from the data obtained on the production performance of 95 Tharparkar cattle. The overall least squares mean of days to reach peak yield, peak yield, lactation milk yield, lactation length and milk yield per day of lactation length were as 43.38± 0.66 days, 12.71± 0.13 kg, 2261.28 ± 37.26 kg, 294.93 ± 2.58 days and 7.62 ± 0.10 kg. The Least Squares Analysis of Variance has revealed highly significant (P<0.01) effect of sire, parity and season whereas significant (P<0.05) effect of period on peak yield, highly significant effect of sire, parity, period and season on lactation milk yield, highly significant effect of sire, period and season on lactation length, highly significant effect of period, parity and season whereas significant effect of sire on milk yield per day of lactation length. The correlation coefficients were significant to highly significant correlated whereas low to moderate heritability was observed in most of the production traits. The significant to highly significant effect of non-genetic factors play important role in performance of animal so higher emphasis on management practices, nutrition and health cover will help in improving the production of animal. The significant effect of sires on almost all production traits under study is indicating that selection of sires can bring improvement in production traits of Tharparkar cattle. The low to moderate heritability observed in most of the traits under study indicated that improvement in management practices can further enhance the better expressibility of these production traits.
