Abstract
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 oviposition, 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.
