The data of 655 Hariana cattle on first lactation and lifetime production and reproduction reared during 1965-2020 at State Livestock and Agriculture Farm, Babugarh, Hapur, India was used for prediction analysis. The accuracies obtained in predictive models for predicting various lifetime production traits (dependent variable) from first lactation traits (explanatory variables) had ranged from 12.2 – 57.9%. The lifetime traits BET and TLMYP/PD can be predicted from first lactation traits with 57.9 and 51.6% accuracies using equations. Accuracies for the rest of the prediction models for lifetime traits from first lactation traits were less than 50%.
