TL;DRAbstract

The fattening efficiency evaluation in broilers, expressed in the European Efficiency Factor (EEF index) requires the information on mortality rate, body mass and feed conversion ratio reached at the age of their delivery to slaughter. This requirement is met by the use of the deterministic simulation model BIOM N 2001. In contrast to the contemporary widely used models of growth that describe the body mass growth as a function of time, the BIOM N 2001 model is based on the conversion of metabolizable feed energy into the gross energy deposited in the tissues of a growing warm-blooded animal. The results, obtained in an experiment with broiler chickens ROSS 208, demonstrate the formal compatibility of this new methodical approach with the classical growth function of Gompertz. The advantage of this new method is its compatibility with variables, generally used at well performing farms in the course of the fattening period, i.e. good agreement between the calculated values and those mea
