The main goal of this research was to thoroughly assess how replacing part of the milk with Soymilk affects the haematological and biochemical parameters, as well as faecal consistency, in Murrah buffalo calves. The calves were randomly divided into three treatment groups: Treatment 1 received only whole milk, Treatment 2 received a 75:25 ratio of whole milk to Soymilk, and Treatment 3 received a 50:50 ratio of whole milk to Soymilk. During the duration of the experiment, all calves were kept within strict feeding protocols and consistent management practices. Monthly blood samples were aseptically collected to thoroughly evaluate the effectiveness of Soymilk as a partial milk replacer through detailed haematological and serum biochemical analysis. Faecal consistency was observed every 15 days for 90 days to systematically assign faecal scores. The results from the experiment showed no significant variations in a wide range of haematological and serum biochemical parameters in the different treatment groups. Also, the dietary interventions had no considerable impact on the faecal ratings of the young calves, suggesting that incorporating Soymilk did not cause any digestive issues. To sum up, this research strongly proves that Murrah buffalo calves can safely replace up to 50% of whole milk with Soymilk without any negative impact on their health or physical abilities. This discovery highlights the possibility of using Soymilk as a practical and efficient substitute in buffalo calf feeding
