Summary: A dairy goat model was built to study the impacts of puberty and lactation order in a herd over time. A system dynamics approach was used to develop the feedback structure of the model, which was programmed into Vensim® . The model was developed to simulate a semi-intensive system where all parameters assumed average values reported in the production system at the Brazilian Agricultural Research Corporations (Embrapa-Goats). Although being a preliminary study, it gives very important insights of better management policies to improve the efficiency of the system by changing the profile of animals in the herd and the age of puberty by changing nutritional conditions.
