The objective of this work is to study the morphometric profile and determine the mathematical models that will be used for the estimation of live weight of adult dromedaries based on body measurements using multiple regression models. We took thirteen body measurements and live weight of 150 adult dromedaries (27 males and 123 females) selected in three different geographical regions of South-East Algeria. Multiple linear regression models were proposed using some body measurements to predict the live weight of dromedaries. The results show that in the separate male model the R² and CCC of Lin increased compared to the general model. The R² values were 95% for males against 84.1% in the general model
