The present study was conducted to estimate the factors affecting the growth and mortality pattern in Tharparkar calves at organised dairy farm. The 8 year 6 month data set was analysed for the effect of season of birth, sex and period of birth on body weight at 0, 90, 180 and 360 days as well as mortality pattern of calves in different seasons. The seasons of birth had significant effect (P<0.05) on body weight at 180 and 360 days. The body weight was significantly higher (P<0.05) during winter and rainy season as compared to autumn at six month of age. The effect of sex was also significant (P<0.05) on body weight, where male calves were significantly (P<0.05) heavier as compared to females at 180 and 360 days. The birth weight was significantly (P<0.01) affected across the period of study. The calves with lesser birth weight led to higher mortality in rainy season (44.44%) as compared summer (19.23 %). The study revealed that winter and summer born calves has better growth and survivability under organised farming conditions.
