Introduction. Genetic companies that work with the different ovipositor lines have achieved advances in the quantitative parameters and provide management guides that suggest techniques and systems of breeding and management to producers, according to the needs of the animals. Objective. Characterize the production parameters of the different ovipositors lines from Hacienda la Montaña, which belongs to Universidad de Antioquia, comparing them with those from the genetic companies. Methodology. The data were collected from poultry flocks in a period between 2002 and 2008, keeping into account, during the breeding and raising stages, the following variables: weight of the hen, quantity of food accumulated, feasibility percentage and duration of the period. For the production stage, the following variables were considered: quantity of food accumulated, average production percentage, eggs per housed hen, age according to sexual maturity, feasibility percentage and persistence in the production. Unidimensional descriptive exploratory analyses were performed to the data collected and the variables evaluated, plus a correlation analysis and a multivariate analysis of variance -MANOVA-. Results. For the breeding and raising stage, the lines that achieved the weight desired were ISA Brown, Hisex Brown and Lohmann LSL. For the oviposi tion, the ISA Brown and Hisex Brown lines achieved better results for the main performance parameters. Conclusion. A good ovipositor is the result of a high quality chicken, and this is why the chickens with the right weight and body composition at the end of the raising and the beginning of the oviposition stage will be more able to maximize the genetic potential.
