We propose mo deIs to analyze animal growlh data wilh lhe aim of eslimating and predicting quanlities of Liological and economical interest such as the maturing rate and asymptotic weight. lt is also studied lhe effect of environmenlal facLors of relevant influence in the growlh processo The models considered in this paper are based on an extension and specialization of the dynamic hierarchical model (Gamerman ' Migon, 1993) lo a non-Iinear growlh curve sdLillg, where some of the growth curve parameters are considered cxchangeable among lhe unils. The inferencc for thcse models are appruximale conjugale analysis Lascd on Taylor series cxpallsiulIs aliei linear Bayes procedures.
