The obtained data in this study were analyzed by the analysis of variance and to know how old the ducks will reached the inflection point and the adult age, theBNT test is being done. The results of the experiment showed that on fast grow phase the real increased dimensions of length was occured (P 0.05). Results of sigmoid regression models showed that the length of dimension of the body reach the point of inflection in the lifespan of less than one week and the fastest growing length dimension is the length of the beak at age of 24.176 weeks of age, followed by the length of the head at the age of 24.444 weeks, then the length of the neck at the age of 28.977 weeks and the last is the length of the body at the age of 29.961 weeks.
