Abstract
Body weight and heart girth are genetic parameters ahich have close leading to strong correlation between them. A strong correlation between age at first breed and age at first calving were also observed. Strong relationship between dairy heifer general apperance could be used by farmer to improve productivity through management improvement. From the correlation between those body traits, model of quadratic regression equation can be developed to predict spesific traits, model of quadratic regression equation can be developed to predict spesific traits that could keep farmera in managing or selecting heifer.
