The aim of this investigation was to study the effect of parity of Murrah buffaloes on immune, growth and health status in their calves. For this study 14 Murrah buffaloes newly born calves were selected from the Livestock Research Centre of National Dairy Research Institute, Karnal, (Haryana) and were divided in to 2 groups (7 in each) based on the parity of their dams (primiparous and multiparous). Their blood samples were collected after calving on day 2^nd, 7^th, 28^th, 42^nd and 56^th for estimation of total immunoglobulin concentration by Zinc sulphate turbidity test. The Mean±SE of total immunoglobulin concentration on day 2^nd, 7^th, 42^nd and 56^th after birth in calves borne to primiparous and multiparous Murrah buffaloes were 29.65±1.28 vs 33.93±1.47, 23.10±0.61 vs 29.98±0.96, 25.29±1.20 vs 27.21±1.45 and 28.39±0.75 vs 31.28±1.09 respectively. The total immunoglobulin concentration was significantly (P<0.05) higher in multiparous group as compare to primiparous. The final body weigh on 90^th day was 70.7±4.89 and 75.98±3.01 for primiparous and multiparous buffaloes born calves, respectively which was significantly higher in later group. Comparatively lower number of total affections were observed in calves born to multiparous buffaloes. It was concluded that in the present study calves borne to multiparous Murrah buffaloes were having better health, immune status and consequently better growth performance as compared to the calves borne to primiparous Murrah buffaloes.
