ABSTRACT
The goal of this study was to characterize, by mathematic models, the growth pattern of Anglonubian goats raised under semi-intensive system. Data from 43 males and 33 females were used to estimate the growth of animals based on non-linear models. The effects from sex, birth month and birth type on living weight and on average daily weight gain (DWG) at different ages were analyzed. The logistic model has proved to be the most adequate one to estimate the growth curves of males and females. The birth type influenced the living weight up to 60 days of age (P
