Description The production, reproduction and production efficiency performances of Friesian crosses was predicted by muzzle measurement technique. Various linear muzzle measurements (basal length" upper length, central length, muzzle span, . muzzle length and muzzle area) were taken. There was a significantly high association oflinear muzzle measurements with various important production, reproduction and production efficiency traits under study. The simple/multiple regression equation of the best R2 value (more than 75%) along with exclusion of multicollinearly related independent variables were developed for total lactational yield in fourth lactation (kg), average oflactation yield up to 4 lactations (kg), average lactation length up to 4 lactations (days), fourth dry period (days), milk yield per day of fourth lactation (kg/day), milk yield per day of fourth calving interval (kg/day) and average milk yield per day of average of 4 calving intervals (kg/day) having R2 value 82.79,90.81,91.02,82.73,99.91,99.47, 99.55% respectively.
